2011-12-06  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* EventRecord/ColourLine.cc, EventRecord/ColourLine.h,
	EventRecord/MultiColour.cc, EventRecord/Particle.h,
	EventRecord/MultiColour.h, PDT/ParticleData.cc, PDT/PDT.h,
	PDT/ParticleData.h, LesHouches/LesHouchesFileReader.cc,
	LesHouches/LesHouchesReader.cc, MatrixElement/ColourLines.h,
	MatrixElement/ColourLines.xh, MatrixElement/ColourLines.cc:
	Merged sextet branch from hg up to 728953b6f091.

	* Utilities/Exception.h (ThePEG): Fixed out-of-scope error in what().

2011-08-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/MaxCmp.h (ThePEG): Put explicit std:: on greater function.

2011-07-15  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Helicity/Vertex/VertexBase.cc: Explicit checking for charge
	consistency in addToList(). For now, electric charge only.

2011-07-08  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/EventGenerator.*, Persistency/PersistentIStream.* : A
	persistent input stream now remembers the globally loaded
	libraries in the initilalization. This is used by The
	EventGenerator to ensure that a dumped generator state gets the
	right libraries. In response to herwig:ticket:355

2011-06-28  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Analysis/HepMCFile.cc, m4/hepmc.m4 : Clarified HepMC version
	support in configure step. Removed superfluous dynamic_cast.

2011-06-20  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Analysis/HepMCFile.cc: Added Interface for HepMC precision
	setting.

	* Repository/Repository.{h,cc}, src/setupThePEG.cc: Instead of
	printing an error message to cerr, the Repository::load() and
	Repository::read(filename) commands now behave like the other repo
	commands and return an error string.  This allows --exitonerror to
	work correctly for load() and read().

2011-06-03  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/StringUtils.h: Added function to write out class names
	from type_info in a readable form. Used in EventGenerator for the
	exception classes.

2011-05-12  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/SimplePhaseSpace.cc (getMagnitude): Made the function
	safer against throwing exceptions due to rounding errors.

2011-04-14  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/CurrentGenerator.h: Slight functionality enhancement
	to be more similar to Current<>.

2011-04-13  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Repository/EventGenerator.cc: Allow MaxErrors to be negative in
	the interface definition. The handling already allows it.

2011-04-09  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/MaxCmp.h: Fixed ininitialized index value in
	constructor.

2011-03-30  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/DebugItem.*: Introduced new class to enable selective
	debugging. It is activated for runThePEG, but should be considered
	experimental.

2011-03-27  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Vectors/LorentzVector.h: Fixed bug where dirPlus, dirMinus and
	dirZ returned double rather than templated value type.

2011-03-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/runThePEG.cc, Repository/EventGenerator.h: Aded possibility
	to add a tag when running so that one .run file can be run
	eg. with different seeds which then also can result in different
	output files.

2011-03-25  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/MaxCmp.h: Added value() function for situations where
	implicit cast does not work.

	* Repository/CurrentGenerator.h: CurrentGenerator::Redirect now
	does not redirect to to the internal stream in EventGenerator if
	the useStdout flag has been set.

2011-03-08  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Utilities/DynamicLoader.cc, PDF/LHAPDF.cc: Workaround for
	correct FPE handling when Fortran libraries are
	present (herwig:ticket:338).

2011-03-06  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/ParticleData.h (cTau): Fixed problem where cTau() reported
	infinite lifetime in case both width and lifetime were set to
	zero.  This is normally the case for stable particles, but it was
	also the case for some default ThePEG default particles such as
	D*0. The result was that these were not decayed if
	Decayer:maxLifeTime was non-zero. The new behavior is that if both
	width and lifetime are zero, cTau() returns zero for unstable
	particles and MaxLength for stable ones.

2011-03-05  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Config/std.h (inserter): Specialized the inserter function for
	vector and deque as the normal inserter function was not safe for
	such containters.

2011-01-21  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/BaseRepository.cc: "." can now be used as a directory
	in 'mset' and friends.

2011-01-20  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/MaxCmp.h: Extended the functionality to include index
	caching and a comparison class. Also added a MinCmp class as a
	specialization.

2011-01-17  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/*EventGenerator.* (flushOutputFile): The .out file is
	now only opened and written in finish(), before that any output is
	cached in a ostringstream. In response to herwig:ticket:329

2011-01-17  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* m4/thepeg.m4: Fixed test for fenv.h to check for
	feenableexcept(), which doesn't exist on OS X.
	Fixes herwig:ticket:328

2011-01-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/EventGenerator.* Repository/BaseRepository.*
	Interface/InterfacedBase.* Interface/InterfaceBase.* (and several
	sub-classes): Added option LogNonDefault in EventGenerator to
	print out all interfaces which are not at their default
	value. Also added possibility in InterfaceBase to flag an
	interface as having no default value (and will therefore not be
	checked in LogNonDefault). Furthermore, added possibility to
	specify a default value on a per-object basis in
	BaseRepository (the 'newdef' command).

2010-12-16  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Repository.h: Added member to return version number
	and a banner.

2010-12-15  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* m4/rivet.m4: Fixed check if Rivet is in system libraries.

2010-11-18  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Analysis/RivetAnalysis.cc: Runerror if not all analyses are found.

2010-11-01  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/Debug.cc: For some reason, the old procedure for
	enabling the signalling of floating-point exceptions, does not
	work anymore. I have included an alternative based on the fenv.h
	system header which seems to work.

2010-10-22  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/Debug.h: There was an inconsistency before where
	whatever you say about debugging at the command-line of runThePEG
	and setupThePEG was ignored in favour of the debug level set in
	the EventGenerator. Now the EventGenerator will only set its own
	debug level if none has been set before by Debug::setDebug().

2010-10-21  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/Exception.h: Added noabort flag. When set, all
	abortnow and maybeabort severities are converted to runerror. The
	flag is set by the EventGenerator after the initrun phase if
	Debug::level is zero. In response to herwig:ticket:325.

2010-10-19  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* PDF/PolarizedBeamParticleData.h: Added default initializers in
	constructor.

	* m4/rivet.m4: Require Rivet >= 1.3

2010-10-17  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/DescribeClass.h: Added a simplified interface to the
	type information system in ThePEG. For simle classes there is no
	need to specialize the ClassTraits and BaseClassTrait classes and
	to have a static member variable of ClassDescription in the
	class (as in the full ThePEG type info system). Instead it is
	enough to have one statically initialized variable of one of the
	DescraibeClass classes for each class. The Abstract and NoPIO
	versions of this class should be used for abstract classes and
	classes without persistent I/O functions respectively.

2010-10-15  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/LastXCombInfo.h (and friends): Included implementation
	of pdf<> function again in the headerfile and removed it from
	PartonExtractor.h. Now uses a new access function has been
	included in XComb to avoid incomplete type.

2010-10-14  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* configure.ac, m4/ax_compiler_vendor.m4: Initial support for
	Intel warning flags. Adjust the ignore set over time.

	* various: Fixes for intel compiler warnings

	* Config/PhysicalQtyOps.h, PDT/PID.h: Simplified template
	overloading

2010-10-06  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Repository/EventGenerator.cc (persistentInput): After reading
	the misc stream from persistent input, we need to seek to the end
	of the stream explicitly. Otherwise, new content will overwrite
	existing lines.

2010-10-05  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/Histogram2D.h (LWH): Added two-dimensional histograms
	in LWH.

	* Handlers/AnalysisHandler.*: Changed default virtual functions so
	that analyze(vector<tPPtr>,double) and analyze(tPPtr,double) takes
	an event weight as argument. The old functions are still there but
	are deprecated. Also the transform functions was flawed. It could
	in principle transform the whole event and then the final-state
	particles would br transformed again. Added transform(tcEventPtr)
	which is used insted of transform(tEventPtr) which is now
	deprecated. This could break some code, but since that code woud
	be flawed anyway, it is not a big deal.

2010-10-05  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Repository/EventGenerator.cc: tic prints out 'init' message

2010-10-01  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* EventRecord/Event.cc: Added energy non-conservation indicators to
	Graphviz output.

2010-09-29  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Utilities/CFile.*: Early throw of exception in case of
	fopen() error. Avoid fclose() on NULL files.

2010-09-28  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* EventRecord/*, Helicity/*: Merged SpinBase and SpinInfo. Base
	classes SpinInfo, HelicityVertex and RhoDMatrix now live in
	EventRecord. This removes the need for frequent dynamic_casts from
	the base to the derived class.

2010-09-09  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Vectors/HepMCConverter.tcc: Converted David fix for
	herwig:ticket:323 to properly use the traits class.

2010-09-09  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Vectors/HepMCConverter.tcc: Bugfix for herwig:ticket:323:
	HepMC converter ignores event weight when using pre-existing event
	objects.

	* PDF/*: Added support for diffractive physics:
	WeizsackerWilliamsPDF extended; LeptonLeptonRemnant renamed to
	UnResolvedRemnant; PDF override options added to PartonExtractor;
	BudnevPDF added.

2010-08-12  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/ParticleData.*: Added interface to switch on a given set of
	decay modes, while switching off all others. In response to
	herwig:ticket:319

2010-07-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Cuts/TwoCutBase.cc (passCuts): Fixed bug noticed by Simon where
	t instead of -t was checked against

2010-06-09  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Helicity/Vertex/{AbstractSSSSVertex.*,Scalar/SSSSVertex.*}:
	Fixed SSSS Vertex inheritance

	* Vectors/LorentzVector.h: Implemented rotate(angle,axis) for
	LorentzVector, too.

2010-05-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Persistency/PersistentOStream.*: Output of real numbers now
	throws an exception if a NaN or an Inf is encountered. The
	resulting file would anyway be useless.

2010-05-11  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Utilities/StringUtils.*: Fixed whitespace definition to include
	CR in addition to LF. Fixes herwig:ticket:302.

2010-04-20  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/LeptonLeptonPDF.cc (xfl): Fixed numerical issue when
	x->1 (see herwig:ticket:224 and herwig:ticket:310).

2010-03-08  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/CFile.*: Added class to be able to use zlib (and in
	the future bzlib) for C-style i/o, especially in CFileLineReader
	and LesHouchesReader. Checking for zlib.h is still switched off in
	configure script.

2010-03-01  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* StandardModel/O1AlphaS.*: Changed the behavior of the thresholds
	in case quarks are exactly massless. Also changed the
	theLambdaFlavour and theMaxFlav variables to be signed to avoid
	warnings when compared to PID objects. (in response to
	herwig:ticket:303)

2010-01-27  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Vectors/ThreeVector.h: Fixed rotate() function to be units-aware.

2009-12-11  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* PDT/PID.h, PDT/ParticleData, Interface/Interfaced,
	Repository/EventGenerator, Repository/Repository: Started using
	particle ID type. At the moment it is almost transparent and will
	convert from 'int' and 'long', and to 'long'. Only the problematic
	conversion from unsigned types will lead to a compile error.

	* StandardModel/O1AlphaS.cc: Fixed unsigned PID compile error.

2009-12-10  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Repository/EventGenerator.cc: Third version of the ExceptionMap
	declaration, since we need the severity to be part of the sort
	order. Otherwise warnings will count towards the MaxErrors cutoff.

	* Repository/EventGenerator.cc: Small change to the misc printout:
	the introductory line is only printed when there is any content.

2009-12-01  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/EventGenerator.cc (EventGenerator::count): Changed
	the declaration of ExceptionMap, since the previous version
	couldn't actually tell the difference between exception classes.

	* Repository/CurrentGenerator.h: Allow for redirecting a stream to
	an internal buffer (instead of to EventGenerator::misc()) in
	CurrentGenerator::Redirect.

2009-11-16  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Repository/Repository.cc: Better message text if input file is
	not found. We've never signalled an error, but always tried to
	continue reading.

	* java/Makefile.am: Fixed OS X problem with case-insensitive
	filenames that I reintroduced earlier.

2009-11-12  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Utilities/DynamicLoader.cc, src/setupThePEG.cc,
	PDF/LHAPDF.cc, Repository/{Base,}Repository.cc,
	java/thepeg.install:
	Removed all runtime usage of environment variables. The
	pkglibdir is now passed via a macro definition at compile time.
	'setupThePEG' and 'runThePEG' are not wrapped in scripts anymore
	and execute directly.

2009-11-06  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/HistogramFactory.h: When checking that two histograms
	have the same bins, only check individual bins if the axis are
	non-uniform.

2009-11-06  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Repository/EventGenerator.cc: Small changes to ordering of LaTeX
	citation strings: Decayers and Analyses come last.

	* Repository/EventGenerator.cc: log() stream now points at
	std::cout instead of std::clog when no filename is given.

	* Repository/EventGenerator.h: Added function to get the
	'useStdout' boolean from the Generator.

2009-11-06  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/RivetAnalysis.cc: Redirect standard output from Rivet
	to the end of the log file.

	* Repository/EventGenerator.*, Repository/CurrentGenerator.h:
	Added public inner class CurrentGenerator::Redirect, which can be
	used to redirect standard output from modules to the log file. In
	fact it is redirected to a temporary stringstream in the
	EventGenerator, which is appended to the log file after the run is
	finished.

2009-11-06  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* m4/vl_readline.m4: Readline support can be switched off at configure
	time with '--disable-readline'.

2009-11-05  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Vectors/LorentzVector.h: Replaced nan with assert in
	LorentzVector::cosTheta()

2009-11-03  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Helicity/*: Fixed helicity direction bug and cleaned up lots of
	redundant code.

2009-10-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* EventRecord/ColourSinglet.cc (ColourSinglet::addJunction): Fixed
	bug in connecting junctions.

	* EventRecord/ColourLine.*: Added create function to connect four
	colour lines with a fifth, giving a source and a sink junction.

2009-10-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/RemnantData.*: Allow access to the decayer object.

	* PDF/SoftRemnantHandler.cc: Set remnantWeight() to zero if a
	parton could not be extracted.

	* PDT/SimpleBaryonRemnantDecayer.*, PDT/RemnantDecayer.*,
	EventRecord/RemnantParticle.*: The RemnantParticle now asks if the
	RemnantDecayer feels it is OK to extract a given parton instance.

2009-10-23  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/RemnantDecayer.*: Added option to respect DIS kinematics but
	to silently change scattered lepton if it doesn't work.

	* src/ThePEGParticles.in: Set fourth generation neutrinos massive
	by default.

2009-10-22  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/ObjectIndexer.h: Added find function synonymous to
	'operator()(IntT) const'.

2009-10-21  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/EventHandler.*, Handlers/StandardEventHandler.*,
	Repository/Repository.cc (Repository::makeRun): Fixed problems
	arising when different particles with the same id was included in
	the same run.

2009-10-19  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/ParticleData.*: Allow for negative values of upper and lower
	cut on the width. Negative values represents no cut.

2009-10-16  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Vectors/*Vector.h: Assertion in cosTheta() and perp2() to catch
	zero-length vectors.  LorentzVector::mag() and mag2() have been
	removed; use m() and m2() instead. The Vector3 class has been
	renamed ThreeVector, in line with the other vector classes and its
	file name.

2009-10-09  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Cuts/Cuts.{h,cc}:
	Added small epsilon to maxSHat comparisons to
	avoid numerical instability when NoPDF is chosen.

2009-10-05  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/ACDCSampler.cc, Handlers/StandardEventHandler.cc,
	Handlers/SubProcessHandler.*,
	Repository/EventGenerator.cc (doinitrun): Made the initrun()
	initialization of ACDICSampler require prior initrun() of the
	StandardEventHandler and, via the SubProcessHandler, also the
	MEBase objects (in response to herwig:ticket:275).

	* Repository/Repository.cc (Repository::help): Added help command
	which hopefully will write out helpful info (in response to
	herwig:ticket:277).

2009-09-30  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Strategy.*, Repository/Repository.cc: Strategy now
	has a DefaultParticlesDirs interface (ParVector of strings). If
	not empty, the scanning of all particles in the repository to
	include particles in a run is disabled and only the directories
	listed are scanned.

2009-09-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/RivetAnalysis.h: Added filename parameter which
	defaults to the run name.

2009-09-10  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Repository.cc (findParticle): If the name is not
	found among the default particles, look through also all other
	particles.

2009-09-09  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* EventRecord/Event.cc (printGraphviz): Added member function to
	call ThePEG::printGraphviz to facilitate usage in debugger.

2009-09-09  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* EventRecord/Event.* (printGraphviz): Moved Graphviz generation
	into Event. Added coloured lines for colour lines. tcc file
	absorbed in header.

	* Analysis/GraphvizPlot.*: Uses new printGraphviz functionality,
	now independent of HepMC.

2009-09-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/LesHouchesReader.cc (LesHouchesReader::createBeams):
	If there are no PDFs used (and NoPDF's are assigned to the reader),
	the incoming particles are the same as the beams. This should fix
	herwig:ticket:273.

	* PDT/DecayMode.cc (DecayMode::constructDecayMode),
	Repository/BaseRepository.cc (BaseRepository::TraceObject):
	(In response to herwig:ticket:271) if an object is not found and
	the name looks like a decay mode, a dummy decay mode is
	constructed and the corresponding, decay tag is generated, and it
	is checked if there is a corresponding DevayMode in the given
	directory. If this is the case, that object is used instead and a
	warning is emitted.

2009-09-04  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Vectors/HepMCConverter.tcc: Relaxed units exception for older HepMC
	versions.

2009-09-01  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* LesHouches/LesHouchesEventHandler.cc (initialize),
	LesHouches/LesHouchesReader.cc (createPartonBinInstances):
	Improved error message in LesHouches reader.

2009-08-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* MatrixElement/MEBase.*, Handlers/StandardXComb.*,
	Handlers/StandardEventHandler.*: Fixed problem with (p)reweighting
	of matrix elements: the sub-process object for the XComb was not
	properly set which caused segfault. Then the reweighting was not
	properly taken into account in the statistics function in the
	StandardEventHandler.

2009-08-19  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/EventGenerator.cc (EventGenerator::generateReferences):
	Order the items in the LaTeX file with references according to
	importance (in response to herwig:ticket:270).

2009-08-18  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/AnalysisHandler.h: Added include for Event.h for
	convenience (herwig:ticket:269).

2009-08-18  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Repository/EventGenerator.{h,cc}: Added new Switch:
	UseStdout. ATLAS requested to receive all output on stdout
	instead of .out .log and .tex files. (herwig:ticket:213)
	Reduced frequent usage of 'endl'.

	* EventRecord/ColourLine.cc (startParticle, endParticle): Leif has
	fixed the determination of start and end particles to only
	consider ones without coloured children.

2009-08-06  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/GraphvizPlot.cc (dofinish): Made the message sent to
	cout optional.

	* lib/inputerror.pm (inputerror): Added small PERL module for
	reading numbers with errors as written out bu ThePEG.

	* Vectors/HepMCTraits.h, Vectors/HepMCConverter.tcc,
	Vectors/HepMCConverter.h: Included support for cross sectio
	information and made the traits class implement cross sections,
	pdf's and units depending on what is set in HepMCDefs.h.

	Also reordered the particles according to their numbering as an
	alternative to CMS's suggested "topological" sorting.

	This will hopefully fix herwig:ticket:153

	* include/Makefile.am (CONFIGHEADERS): Make sure
	Config/HepMCHelper is properly symlinked.

	* Analysis/GraphvizPlot.cc (particleName): Added helper function
	for getting the name of a particle to be able to handle remnant
	particles (which have code 82).

2009-08-05  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* EventRecord/ColourLine.h: Handle possible segfault in
	start/endParticle() more gracefully. Also, source and sink were
	the wrong way round.

2009-07-06  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* PDF/LHAPDF.cc, PDF/Makefile.am: Also look in ThePEG's pkgdatadir
	for the PDFsets.index file.

2009-06-18 Simon Pltzer <sp@particle.uni-karlsruhe.de>

	* StandardModel/*Alpha*, StandardModel/RunningCoupling.*,
	StandardModel/Makefile.am:
	Changes to unify the treatment of running couplings, providing
	scale factors, helpers to veto algorithms and information about
	the number of loops entering the beta function to perform
	consistency checks.

2009-06-15  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/EventHandler.*, Handlers/StandardEventHandler.*,

	* configure.ac, m4/thepeg.m4: Added summary output after
	configure is run.

2009-06-09  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/LesHouchesReader.cc (initStat): Fixed bug where the
	sum of the maximum weights was calculated instead of the
	maximum. This will hopefully finally fix herwig:ticket:248

2009-05-22  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/LesHouchesEventHandler.cc: The cross section for
	different processes in the same LesHouches reader was not reported
	correctly (herwig:ticket:248). This is now fixed.

2009-05-21  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/UnitIO.h: herwig:ticket:254 Fixed ouniterr() so that
	nan's and inf's are written out as such and don't throw nasty
	exceptions.

2009-05-18  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/StandardEventHandler.cc (addME): herwig:ticket:253
	Fixed so that before determining whether or not a diagram should
	be mirrored to match the incoming partons, the diagram partons are
	temporarily ordered so that the first never has a id lower than
	the second.

2009-05-11  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/HistogramFactory.h: Fixed bug in divide and multiply so
	that the weighted bin center does not goes wild.

2009-05-01  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Helicity/WaveFunction/*.h: Removed lots of redundant, unused
	constructors.

2009-04-30  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Helicity/RhoDMatrix.h: Worked around gcc 4.1.2 compiler bug on
	x86_64. The 'norm = 1/norm' line was omitted if optimization was
	higher than -O1.

2009-04-16  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Cuts/*: Added describe() functionality. Called during initrun()
	if Debug::level is set, it will print the ranges of the active cuts to
	the logfile.

2009-04-02  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Repository/EventGenerator.*: Setting dumpPeriod to -1 will now
	disable dumping completely, even in the case of errors.

	* Repository/Repository.*, configure.ac, m4/vl_readline.m4,
	lib/Makefile.am: Implemented basic readline support for the
	interactive mode. Will fall back to previous method if not reading
	from std::cin, or readline is not available.

2009-03-10  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* m4/*: Updated libtool files to version 2.2.6

2009-03-02  Mike Seymour  <Mike.Seymour@cern.ch>

	* Vectors/HepMCConverter.tcc: Fixed minor bug leading to incorrect
	PDFInfo when the two beam particles are different.

2009-02-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Config/Pointers.h (ThePEG_DECLARE_POINTERS): Changed macro so
	that they can be used to easily typedef pointers outside the
	ThePEG namespace.

2009-02-11  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Persistency/PersistentOStream.h: Added output operator for
	c-style strings as requested in ticket #231.

	* LesHouches/LesHouchesReader.*: Added interfaced flag
	WeightWarnings to avoid warnings about inconsisten weight
	warnings. The default is still to issue warnings.

	* include/ThePEG/Vectors/Transverse.h: Removed
	operator/(Transverse<Value> a, double b) as it caused ambiguous
	overloads when unitchecks were turned off, and as it wasn't really
	needed.

2008-12-10  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* LesHouches/LesHouchesReader.cc: Fixed several segfaults when
	LHE file is inconsistent with repository settings.

2008-12-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/Current.h (ThePEG): Added general class for accessing

	warning if LHE file does not include proper MadGraph header.

2008-11-20  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/MultiEventGenerator.* (MultiEventGenerator::doGo):
	Header with sub-run information is now written also to the log file.

2008-09-24  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Vectors/Transverse.h: Fixed bug where named arguments were
	omitted when moving the implementation from the .icc files.

2008-09-23  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* *: Global icc cleanup. Tested with several Herwig long runs.

2008-09-15  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* EventRecord/*, PDT/*: icc removal.

	* EventRecord/Particle.*: Reduction of needless rep() constructions for
	'get' type member functions. 'theRep' no longer needs to be
	mutable. Checked with several long Herwig++ runs, 1.5% runtime
	improvement.

	* PDT/ParticleData.*, PDT/PDT.*, PDT/MatcherBase.* :
	Inconsistent colo(u)r spelling unified to British only.
	Previously, MatcherBase used American only, Particle used
	British only and PDT and ParticleData offered both.

	* PDT/ParticleData.* : Strings now passed by reference.

2008-09-12  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Vectors/HepMCTraits.h, Vectors/HepMCConverter.*: Introduced
	units for HepMC. By includeing GenEvent.h and checking if the
	Units.h file also was included, the default behavior of the traits
	class should be correct. (herwig:ticket:202)

	* Config/Unitsystem.h: Added centimeter which may be used as a
	unit in HepMC.

	* Analysis/FactoryBase.h, configure.ac, Config/LWH.h.in,
	m4/thepeg.m4: Configure now checks for AIDA header files and
	includes them instead of the stubs in LWH. This will hopefully fix
	some of the problems in herwig:ticket:198

2008-09-10  Peter Richardson  <Peter.Richardson@durham.ac.uk>

	Vectors/LorentzVector.h: Added a member to mass squared of two vectors
	to avoid additional memory allocation and made strings for error messages
	constant to avoid allocation/deletion overhead was using 1.5% of time when
	generating LEP events with Herwig++.

2008-09-09  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Vectors/Transverse.*: Added function to multiply and divide with
	scalar.

	* PDT/ParticleData.icc: Fixed cTau() function to return
	hbarc/theWidth it theCTau is zero.

2008-08-29  Peter Richardson  <Peter.Richardson@durham.ac.uk>

	* PDF/*: Added a member to calculate the sea pdf as this is needed
	in Herwig++ and can often be computed faster than by just taking
	the difference of the full PDF and the valence only piece.

2008-08-29  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Helicity/*: Cleaned up RhoDMatrix and SpinInfo after profiling
	showed inefficiencies.

2008-07-04  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/DecayHandler.cc (performDecay): Introduced MaxLifeTime
	parameter and corresponding variable to prevent particles with
	longer lifetime than this to decay (herwig:ticket:199).

2008-06-16  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/LWHFactory.cc: The LWH namespace is renamed to
	ThePEGLWH to avoid problems with using the Rivet versions of the
	LWH classes (herwig:ticket:198).

2008-06-09  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* PDF/LHAPDF.cc, m4/thepeg.m4: Removed usage of lhapdf-config. The
	same information can be obtained at configure-time, and is passed
	in with a '-D' compile flag.

2008-05-29  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* PDT/DecayMode.*: Made theOrderedProducts a tPDVector to break
	possible dependency loops.

2008-05-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/setupThePEG.cc, Repository/(Base)Repository.*: Added
	possibility to specify include directories for looking for .in
	files. setupThePEG now takes flags -I and -i to prepend and append
	search paths. BaseRepository has functions prependReadDir and
	appendReadDir for the same purpose.

2008-05-25  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/RandomGenerator.*,
	Repository/StandardRandom.* (StandardRandom::setSeed): The
	documentation of the Seed interface did not match the
	documentation and behavior of the setSeed function. Changed so
	that setting Seed to 0 will not give a new seed to the generator,
	while -1 will give a standard seed.

2008-05-24  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/Makefile.am, src/MultiLEP.in: Added test of
	MultiEventGenerator.

	* Repository/MultiEventGenerator.cc (MultiEventGenerator::doGo):
	Fixed various bugs relating to resetting and finalizings.

	clear() before initializing in case of multiple runs.

2008-05-20  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Utilities/FixedSizeAllocator.*, EventRecord/{Collision,Particle,
	Event,Step,RemnantParticle,SubProcess,EventConfig}.{h,icc}:
	Removed FixedSizeAllocator. Timing 10000 default Herwig++ LHC
	events shows a speedup of 5%: 720 s now vs. 756 s before.

	* m4/, src/Makefile.am, configure.ac, Config/ltmain.sh,
	include/Makefile.am, Makefile.am: Included libtool 2.2.4 in the
	tarball. Moved acinclude into m4/thepeg.m4.

2008-05-19  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/StandardEventHandler.cc (StandardEventHandler::statistics):
	Fixed so that the statistical error on the total cross section is
	still well approximated if some events are vetoed. (herwig:ticket:174)

	* ACDC/ACDCGen.icc: Fixed? bug in calculating the statistical
	error. (herwig:ticket:174).

2008-05-17  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/UnitIO.h: Introduced IUnitErr and iuniterr to read in
	numbers with error estimates written out by OUnitErr. Also
	introduced specializations of ouniterr and iuniterr for double
	without unit argument. In response to herwig:ticket:174.

2008-05-16  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Repository.cc (Repository::exec): Fixed bug in
	creating decay modes for non-synchronized
	particles (herwig:ticket:182).

2008-05-13  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/LesHouchesEventHandler.cc
	(LesHouchesEventHandler::statistics): Now writes out cross
	sections with statistical error estimates. In response to
	herwig:ticket:174.
 
	* Handlers/StandardEventHandler.cc (StandardEventHandler::statistics):
	Now writes out cross sections with statistical error estimates.
	In response to herwig:ticket:174.

	* Utilities/UnitIO.h: Introduced OUnitErr and ouniterr to nicely
	write out (unitful) numbers with error estimates.

	* Handlers/ACDCSampler.*, Handlers/SamplerBase.h: Also keeps track
	of the statistical error.

	* ACDC/ACDCGen.* (ACDCGenerator): ACDCGen now gives a better
	estimate of the integral and in addition estimates the statistical
	error.

2008-05-05  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* MatrixElement/ME2to2Base.cc (ME2to2Base::getCosTheta): Fixed
	precision problem according to Peters suggestions in
	herwig:ticket:172.

2008-05-02  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/StandardEventHandler.cc: Preparing for having errors on
	the statistice output.

	* Cuts/Cuts.cc (Cuts::passCuts): Stupid bug fixed, and
	herwig:ticket:172 seems now to be solved.

	* Handlers/StandardXComb.cc, Cuts/Cuts.* (Cuts::initSubProcess):
	Make Cuts aware that a matrix element may be generating
	sub-processes which are mirrored along the z-axis. This will
	hopefully fix herwig:ticket:172.

2008-04-30  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/CompSelector.*, LesHouches/LesHouchesEventHandler.*:
	CompSelector will now only start compensating if a weight is
	larger than unity by some tolerance factor. This is used by the
	LesHouchesEventHandler.

	* PDT/ParticleData.cc,
	Repository/Repository.cc (Repository::exec): After "setup" a
	particle is now added to default particles and also to matchers by
	the Repository rather than in the ParticleData::readSetup
	function.

	* PDT/ParticleData.cc: Changed readSetup() so that if '-' is given
	as the PDGName the object name will be used instead.

2008-04-29  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Strategy.cc (Strategy::setLocalParticlesDir): Allow
	setting an empty string, to indicate that no directory should be
	searched.

2008-04-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/MadGraphReader.cc (MadGraphReader::open): The
	MadEvent file format has changed (AGAIN!) so things that were
	previously outside the <header> is now inside.

2008-04-27  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Repository.*, PDT/DecayMode.cc: Removed
	Repository::findParticleByPath, findParticle now has the same
	behavior. Removed the obsolete special treatment of decay modes in
	the Repository.

	* src/ThePEGParticles.in, PDT/ParticleData.cc: In readSetup a
	particle will add itself to the default particles if no particle
	with the same id was not present before. The "defaultparticle"
	commands was therefore removed from ThePEGParticles.in.

	* Repository/Repository.cc (Repository::findParticleByPath): Added
	function to first seach a particle according path, before
	resorting to finding default particle. The behavior of the
	"decaymode" command uses the new DecayMode::constructDecayMode
	behavior.

	* PDT/DecayMode.* (DecayMode::constructDecayMode): Redesigned
	recent changes. If the decaying particle is a valid path to a
	particle object the decay mode will be added to that
	particle. Otherwise the decay mode will be added to the
	corresponding default particle.

2008-04-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Repository.cc (Repository::exec): Changed the
	behavior of "decaymode" again. Now, if what preceedes the "->" in
	the decay mode tag corresponds to a valid path to a particle, the
	decay mode will be added to that particle, otherwise the previous
	behavior is maintained.

2008-04-25  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Repository.cc,
	PDT/DecayMode.* (DecayMode::constructDecayMode): If "decaymode"
	specifies an object name which is in a subdirectory of a particle,
	the created decay mode will be added to the corresponding
	particle. If only a decay tag is specified the decay mode will be
	added to the corresponding default particle (the old behavior).

	* Repository/Repository.cc (Repository::makeRun): Use the
	LocalParticlesDir in the Strategy object to find default
	particles.

	* Repository/Strategy.* (Strategy::setLocalParticlesDir): Added
	interface to specify a directory which is scanned for particles
	which are treated as default particles for the given strategy.

	* Interface/*: Now uses 'setuperror' severity in exceptions. Also
	catches InterfacedException's by reference to avoid duplicated
	output.

	* Utilities/Exception.*: Added new severity level 'setuperror' to
	be used during the setup phase.

	* LesHouches/LesHouchesReader.cc (LesHouchesReader::createParticles):
	Fixed bug in checking for colour-line consistency.

2008-04-23  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/LesHouchesReader.cc (LesHouchesReader::scan): Removed
	unused variable 'xlast'.

	* PDF/LHAPDF.cc: Fixed spelling in error message.

2008-04-15  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Repository.cc (Repository::exec): Implemented "rm",
	"rmdir" and "rrmdir" commands to override the ones in
	BaseRepository This fixed the bug that particles and decay modes
	were not properly removed and that rrmdir was absurdly slow when
	removing large directories.

	* Repository/BaseRepository.cc: Fixed bug where error message from
	remove() was not checked in "rrmdir" command. ("rrmdir" still
	unecessesarily slow.)

2008-03-30  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/SimpleLEP.in, src/Makefile.am: Include a test that the run
	inside setupThePEG gives exactly the same result as the runs in
	runThePEG, both when run from the beginning and when resumed.

	* src/runThePEG.cc, Repository/EventGenerator.*,
	Repository/MultiEventGenerator.* ((Multi)EventGenerator::doShoot):
	Enable the possibility to resume the execution from an
	interrupted (and possibly dumped) run.

	* Pointer/ReferenceCounted.h, Persistency/PersistentOStream.*,
	Persistency/PersistentIStream.*: The uniqueId used to sort
	pointers in the ReferenceCounted class is written to the file and
	can optionally be read back in. For this reason the
	PersistentIStream was made a friend of ReferenceCounted.

	* Persistency/PersistentOStream.icc: Increased the number of
	significant digits when writing out floating point numbers to
	avoid divergent random number sequences.

2008-03-29  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/XSecStat.cc: Fixed bug in input function.

2008-03-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	pows to enable l-values closer to zero without overflow.

2008-03-24  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/ClassDescription.fh: Added forward declarations for
	all description classes.

2008-03-20  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/Debug.cc (Debug::unmaskFpuErrors): Removed the
	unmasking of denormalization exceptions, as these are not really
	errors.

	* LesHouches/LesHouchesEventHandler.cc: Changed call to rndPoisson
	to match new implementation.

	* Repository/UseRandom.*, Repository/RandomGenerator.*:
	RandomGenerator can now be used with gsl random number
	distributions. In particular rndPoisson now uses gsl_ran_poisson,
	and no longer need the maximum argument.

	* src/Makefile.am, configure.ac, acinclude.m4: Included check for
	gsl, on which ThePEG now depends.

2008-03-17  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/XSecStat.*, Handlers/StandardXComb.*,
	Handlers/StandardEventHandler.*, LesHouches/*: Fixed bug in
	previous fix of XSecStat affecting generation of weighted events.

2008-03-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Vectors/HepMCConverter.*: Added convert function which fills a
	given GenEvent rather than creating one internally. This fixes
	herwig:ticket:160.

2008-03-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/XSecStat.*: Fixed bug in reject function which could
	give incorrect statistics.

2008-02-14  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Repository.*, src/setupThePEG.cc: Introduce
	constructor and destructor in the Repository to allow for
	cleanup. Create a Repository object in setupThePEG to allow for
	cleanup.

	* Handlers/XComb.cc (XComb::clean): Do not create new
	partonBinInstances, just set the pointers to NULL. Instead create
	new partonBinInstances in prepare().

2008-01-24  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/StandardXComb.cc (dSigDR): Moved call to
	MEBase::dSigHatDR to after call to PDFs and made it contitional to
	PDFs being non zero. This fixes herwig:ticket:136

2008-01-23  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Vectors/HepMCTraits.h, Vectors/HepMCConverter.tcc,
	Vectors/HepMCConverter.h: Added possibility to choose in which
	units lengths and energies should be stored in GenEvent.

2008-01-15  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/LesHouchesFileReader.*: Made class concrete.

2008-01-13  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/setupThePEG.cc, Repository/Repository.cc
	Repository/BaseRepository.*: Added commands to specify global
	libraries.

	* Persistency/PersistentOStream.cc: global libraries are now
	outputted with main version number.

2008-01-12  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Persistency/PersistentIStream.cc,
	Persistency/PersistentOStream.*: Added possibility to specify
	shared libraries to be loaded before of persistent objects.

	which interface should be used instead. (ticket #124)

2007-12-14  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/StandardEventHandler.cc: Fixed integratedXSec() so that
	it really returns the overestimated xsec if no events have been
	generated.

	* Handlers/ACDCSampler.cc, Handlers/ACDCSampler.h,
	Handlers/SamplerBase.h: Added access function to get overestimated
	cross section.

2007-11-30  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Pointer/RCPtr.icc: For consistency also pointer comparison with
	bare pointer uses uniqueId.

	LWHFactory into its own dynamic library.

2007-11-23  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Pointer/ReferenceCounted.*, Pointer/RCPtr.icc: Added uniqueId to
	all reference-counted objects, to be able to sort RCPtrs in a
	platform-independent manner. Fixes Herwig ticket #46.

2007-11-14  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	if a given PDF or parton bin has a pole at x=1. Fixes ticket #119

2007-11-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/XSecStat.icc: xSec() and xSecErr() now returns
	maxXSec() if no attempts have been made.

	* LesHouches/LesHouchesEventHandler.cc: Remember to set
	theIncoming particles in the EventHandler base class.

2007-09-06  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/StandardEventHandler.cc: Only clean() the previous
	XComb in select() if it is not the newly selected one.

2007-09-05  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Handlers/StandardEventHandler.cc: In select(), clean up
	theLastXComb before switching to a different one. This fixes
	Herwig bug #89, where stale XComb objects still contained
	information about past events that had long been cleared.

	* Helicity/Vertex/Scalar/GeneralSVVVertex.*: cherstn added
	evaluate member turning two vector wave functions into scalar wave
	function 

	* Helicity/Vertex/VertexBase.icc: cherstn added additional option
	for propagator 

	* Helicity/WaveFunction/*WaveFunction.*: efficiency fix: wave()
	now returns a const reference instead of copying

	* Config/Units_*checked.h: Added InvArea and InvLength

2007-07-11  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Config/Units_*checked.h: Added more predefined units, renamed mm
	to millimeter, to avoid clash with common variable name.

	* Config/ThePEG.h, PDF/LHAPDF.cc, Utilities/Math.h,
	Utilities/DynamicLoader.cc, Utilities/CFileLineReader.cc,
	Utilities/Math.cc, Utilities/Debug.cc, Utilities/Math.icc,
	include/Makefile.am, LesHouches/LesHouchesReader.icc,
	LesHouches/LesHouchesReader.cc, LesHouches/LesHouchesReader.h:
	Removed dependecy of installed headers on config.h, to avoid
	conflicts with other Autotools code. config.h is no longer
	installed. 

2007-07-09  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Vectors/ThreeVector.h: fixed inline specifier

	* Vectors/LorentzVector.h, Config/PhysicalQtyComplex.h:
	workarounds for g++-3.3 bugs 

	* Utilities/UnitIO.h: Fixed iunitstream for complex dimensioned
	quantities. 

2007-07-05  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* CLHEPWrap/*, Vectors/*: Renamed CLHEPWrap to Vectors

	* Helicity/*: Migrated WaveFunctions and Scalar/Vector/Tensor
	vertices from Herwig++.

2007-07-03  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Config/std.h, Config/Units_unchecked.h: Fixed ambiguous 
	overload problem which shows up with g++-3.4.3

2007-07-02  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* *** GLOBAL ***: Merged in relevant changes from the
	STRICT_UNITS_BRANCH. Dimensionful quantities need to have correct
	types, CLHEP dependencies have been removed completely.
	Unit checking can be disabled with --disable-unitchecks, note that
	the code will NOT be backwards compatible either way!

2007-06-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/CascadeHandler.*: Added possibility to assign new PDF
	objects instead of those set in handle().

	* PDF/PDF.*: Added constructor and access to the PDFBase and
	ParticleData objects explicitly.

	* LesHouches/LesHouchesReader.*: Check that the colour flow in the
	Les Houches common block is consistent.

	* EventRecord/Event.*: Fixed the numbering of particles. Before
	the numbering could get screwed up if particles were removed from
	the event (which did not happen very often).

	* EventRecord/Step.*, EventRecord/Event.*,
	EventRecord/Collision.*: Added removeSubProcess function.

	* PDT/RemnantData.*, EventRecord/RemnantParticle.*: Added remove
	function.

2007-06-27  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/setupThePEG.cc, src/runThePEG.cc: Added command line option
	to dynamically load specified libraries before reading persistent
	files.

	* EventRecord/Particle.cc: Fixed printout to also report multiple
	colour lines.

	virtual functions to retreive multiple colour lines. Also fixed
	clone function for MultiColour.

	* EventRecord/Step.cc: Fixed bug in removeEntry where a particle
	was being erased from theParticles even though it was not in
	there.

2007-06-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* EventRecord/SubProcess.*, EventRecord/Step.*: Added debugme()
	function.

	* EventRecord/RemnantParticle.*: extract() and reextract() now
	optionally does colour connections. Not quite sure it works yet.

2007-06-25  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/RemnantData.cc: Changed the PDGId of the remnant from being
	the number of the parent particle to 82, which is the convention
	in Herwig++.

2007-05-31  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/LHAPDF.*: Added interface to limit the number of flavours
	which are reported to avoid problems where the remnant handler
	refuses to handle extracted top quarks. The default maximum is set
	to 5, which means no top quark densities are given.

2007-05-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Persistency/PersistentIStream.*: The stream now throws an
	exeption if something goes wrong (if Debug::level != 0).
	The exceptions messages were somewhat enhanced.

	* Interface/InterfacedBase.*, Interface/Interfaced.*,
	EventRecord/Particle.*, EventRecord/Event.*: Introduced debugme()
	functions.

	* Config/Makefile.am, Config/ThePEG.*: Introduced a non-virtual
	debug() function which calls a virtual debugme() function for any
	polymorphic object in ThePEG

2007-05-25  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Config/Containers.h: Fixed bad stream output for ounit(std::map<>)

2007-05-21  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* CLHEPWrap/HepMCConverter.tcc: Fixed memory leak, where several
	GenParticle's were created for the same ThePEG::Particle instance.

2007-05-18  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Config/*: introduced configure switch to turn off template
	unit checking. Currently needs full rebuild of code by hand
	whenever this configure flag is changed.

	* (various files): removed obsolete CLHEP references
	
2007-05-18  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/UseRandom.*, Repository/StandardRandom.*,
	Repository/RandomGenerator.*: Modified to no longer use
	CLHEP::RandomEngine. StandardRandom now directly implements the
	JamesRandom engine.

	* PDT/WidthGenerator.cc, PDT/ParticleData.cc,
	PDT/BreitWignerMass.cc, LesHouches/LesHouchesEventHandler.cc:
	Fixed to use new RandomGenerator.

2007-05-02  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/MadGraphTwoCut.cc, Cuts/TwoCutBase.cc,
	Cuts/KTClus.cc: Fixed bug in calculating delta-R where the
	phi-difference was always zero.

2007-04-17  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/TestLHAPDF.cc: Also test that valens densities works
	properly.

	* PDF/PDFBase.h, PDF/PDFBase.cc: xfvx and xfvl now gives sensible
	values for baryons even if not overridden in base classes.

	* PDF/LHAPDF.h, PDF/LHAPDF.cc: Make sure xfvl calls xfvx rather
	than the base class xfvl.

2007-03-23  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/EventGenerator.cc: Make sure theCurrentEventHandler
	is set for the initrun() calls.

	* Handlers/CascadeHandler.*: Removed theEventHandler variable and
	associated code as this is handled in the StepHandler base class.

2007-03-22  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/StandardEventHandler.h: Removed unused and
	unimplemented 'compensating()' member function.

	* Handlers/StandardEventHandler.*: Removed unused member variable
	theNDim.

	* lib/ThePEG.el: Corrected argument types for template for
	StepHandler::handle().

2007-03-17  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Cuts/SimpleKTCut.*: Added a maximum kt cut on popular demand.

2007-02-27  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/LesHouchesReader.cc: Added extra checks to make sure
	momentum fractions were not larger than unity.

2007-02-18  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/MadGraphReader.cc: If the number of events in a file
	could not be determined, the XMAXUP was set to zero which
	prevented running with weighted events. This is now fixed, but the
	reported cross section will probably not come out right.

2007-02-06  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/HistogramFactory.h: Fixed divide-by-zero in divide
	function. Also fixed bug in error calculation in divide
	function. Introduced checkBin function to make sure two histograms
	are equal even if they have variable bib widths.

	* Cuts/Cuts.icc: Fixed typo-bug where the cuts in x1 were used for
	cuts in x2.

	* PDF/PartonBinInstance.cc: Call reset() in prepare() to avoid
	dangling pointers.

	* Analysis/Histogram1D.h: In normalize(double), do not do anything
	if the sum of the bins are zero to avoid dividing by zero.

2007-02-03  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/PartonExtractor.cc: In addNewRemnants, fix so that previous
	remnants are still the children of the incoming particle, but also
	the parent to the new remnants (the new remnants are also the
	children of the incoming particle).

	* EventRecord/Particle.cc: In printout, order the parents and
	children to make it more readable.

2007-01-31  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/AnalysisHandler.cc, Handlers/AnalysisHandler.h: The
	documentation of the main analyze() function was inconsistent with
	what was actually done. In particular, the event was not
	transformed as promised. This transformation is now implemented
	and the documentation is updated.

2007-01-29  Nils Lavesson  <nils@thep.lu.se>

	* MatrixElement/MENCDIS.cc: Fixed a bug in the coupling of the Z
	to antiparticles.

2007-01-25  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Handlers/EventHandler.h: removed default argument of newStep(). 
	It now explicitly requires a pointer to the responsible handler.

2007-01-16  Nils Lavesson  <nils@thep.lu.se>

	* MatrixElement/MENCDIS.cc: Included Z exchange and gamma Z
	interference in the neutral current DIS matrix element.

2007-01-12  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/GRVBase.cc: Remove Timer call.

	* PDF/SoftRemnantHandler.cc: Rotate the remnant momentum directly
	rather than going via the particle and a LorentzRotation.

	* PDF/LeptonLeptonRemnant.cc: Rotate the photon momentum directly
	rather than going via the particle and a LorentzRotation. This
	saves 10% in execution time, mainly by avoiding the
	SpinHalfLorentzRotation, which is not used anyway.

2007-01-08  Pete's account  <Peter.Richardson@durham.ac.uk>

	* Helicity/LorentzSpinorBar.cc (Repository): change to give same sign for
	conjugated spinors as if directly calculated and fix compiler warning1

2007-01-05  Peter Richardson  <Peter.Richardson@durham.ac.uk>

	* Helicity/LorentzSpinor.cc (Repository): Changes to return correct
	spinor type after charge conjugation and make bar() method const

2006-12-20  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/SimpleBaryonRemnantDecayer.h,
	PDT/SimpleBaryonRemnantDecayer.cc: If momentum shuffling was not
	possible, and respectDIS is true, try redoing it without
	respectDIS (emitting a warning) before giving up and throwing an
	exception.

	* PDT/RemnantDecayer.icc, PDT/RemnantDecayer.h: Added exception
	class and made respectDIS mutable and protected.

	* PDT/RemnantDecayer.cc: Make sure that exceptions thrown by CLHEP
	when taking the rapidity fails are caught and a proper Exception
	is thrown instead. Also make sure that remnants of colliding
	particles are not included when shuffling momentum.

	* PDF/PartonExtractor.cc: Fixed bug in boostRemnants which only
	showed up in DIS events where the incoming electron has no pdf.

	* Cuts/SimpleDISCut.icc, Cuts/SimpleDISCut.h,
	Cuts/SimpleDISCut.cc: Added a (post) cut in W^2.

	* Cuts/Cuts.cc: Make sure that the TwoCutBase::passCuts is called
	with the incoming partons in the right places.

2006-12-16  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/MaxCmp.h, Utilities/MaxCmp.icc, Utilities/Makefile.am:
	Added new utility class to be used in loops where one would like
	to keep track of the largest value so far of a certain expression.

2006-12-15  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* acinclude.m4: Ticket #78. Changed LHAPDF options from 'enable'
	to 'with'. Also, configure will now produce an error if
	--with-LHAPDF is requested but no library was found.

2006-12-13  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/SimpleBaryonRemnantDecayer.cc: Fixed problem where only one
	particle is used to shuffle momentum. Its momentum was before
	boosted to its desired value which could cause problems. Now the
	momentum is simply set.

	* src/ThePEGDefaults.in, src/TestLHAPDF.in, src/LHAPDFDefaults.in:
	Now uses new remnant treatment.

	* PDF/PartonBinInstance.cc: Fixed bug where x-values could come
	out wrong if created from already generated partons.

	* PDF/BaryonRemnants.h: Changed documentation. This class is now
	deprecated.

	* LesHouches/LesHouchesReader.h, LesHouches/LesHouchesReader.cc:
	Removed the ScanPDFs interface and related function.

	* EventRecord/Particle.cc: If a particle is copied, the parents of
	the new copy is cleared.

2006-12-12  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/FactoryBase.cc: Fixed bug where theTree was not
	properly deleted.

2006-12-11  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* MatrixElement/ME2to2Base.cc: Fixed bug in jacobian for the new
	options in getCosTheta.

2006-12-10  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Cuts/Cuts.cc: Fixed bug in passCuts(const Collision &). The
	documantation states that the collision should be given in its
	rest frame, but the code assumed it was given in the lab frame.

	* PDF/LeptonLeptonPDF.cc: Modified flattenL to use the minimum
	rather than the maximum scale if available.

2006-12-09  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* MatrixElement/ME2to2Base.cc: Added option in getCosTheta to more
	efficiently generate DIS-like diagrams.

2006-12-08  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/StandardXComb.cc: Fixed minor inconsistency in dSigDR
	where the shat was not updated for the Cuts object.

	* Cuts/SimpleDISCut.cc: Fixed bug in passCuts where Q^2 was
	calculated incorrectly.

	* Cuts/Cuts.cc: Fixed bug in passCuts where the momentum of the
	incoming particles was set incorrectly.

2006-12-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/Decayer.cc: Fixed error message in DecayParticle.

	* PDF/PartonExtractor.cc: If a single remnant, set its momentum
	rather than boosting it to the desired value.

	* EventRecord/Event.icc, EventRecord/Event.h: Fixed bug in
	argument to getFinalState.

2006-12-07  Nils Lavesson  <nils@thep.lu.se>

	matrix element.

2006-12-02  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/EventHandler.cc: Fixed so that checkConsistency() does
	not dump events if the warning is not printed.

2006-12-01  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/Decayer.h PDT/Decayer.cc: Introduced static DecayParticle
	function to administer the decay of a particle.

	* Handlers/DecayHandler.xh, Handlers/DecayHandler.h,
	Handlers/DecayHandler.cc: Moved much of the machinery to
	administer the decay a particle to Decayer::DecayParticle.

	* Repository/BaseRepository.cc, Repository/Repository.cc,
	Utilities/DynamicLoader.cc: Increased error information when
	dynamic loading fails.

2006-11-30  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/UtilityBase.icc Utilities/UtilityBase.h: Introduced
	getTransformtoMomentum to replace old (and unreliable)
	transformToMomentum function. The new functions require an
	auxiliary vector to make the transformation unique.

	* Handlers/DecayHandler.cc: Fixed typo in error message.

2006-11-29  Peter Richardson  <Peter.Richardson@durham.ac.uk>

	* Helicity/LorentzSpinor(Bar).{h,icc,cc}: Added new method to
	apply the the charge conjugation matrix to turn u spinors into
	v spinors for use with Majorana fermions

2006-11-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* CLHEPWrap/HepMCConverter.tcc, CLHEPWrap/HepMCConverter.h: Added
	option to convert() function to not include particles with next()
	pointers in the HepMC::GenEvent. This will hopefully avoid nasty
	looking vertices in HepMC.

	* acinclude.m4: Added macro to check if stand-alone HepMC is
	installed.

2006-11-24  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/XSecStat.icc: Fixed bug where the sumWeights2()
	function returned theSumWeights rather than theSumWeights2.

2006-11-18  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* EventRecord/Particle.icc, EventRecord/Particle.h,
	EventRecord/Particle.cc: Made sure that connected ColourLine is
	informed when a Particle is deleted to avoid dangling pointers.

	* src/TestRemnants.in, src/Makefile.am: Added test run for new
	remnant handling.

	* Repository/EventGenerator.icc, Repository/EventGenerator.h,
	Repository/EventGenerator.cc: Implemented variable and function to
	return the sumed weights of all generated events. Also added
	function to return the total cross section.

	* LesHouches/LesHouchesEventHandler.h,
	LesHouches/LesHouchesEventHandler.cc,
	Handlers/StandardEventHandler.h, Handlers/StandardEventHandler.cc:
	Implemented function to return total cross section. Fixed
	histogramScale function to work properly for weighted events.

	* Handlers/EventHandler.h, Handlers/EventHandler.cc: Added
	function to return the total Monte-Carlo integrated cross section.

	* Handlers/AnalysisHandler.h, Handlers/AnalysisHandler.cc: Added
	const access function to histogram factory. Added normalize
	functions.

	* Analysis/FactoryBase.h, Analysis/LWHFactory.h: Renamed misspelt
	normalize function.

	* Analysis/LWHFactory.cc: Implemented the normalize* functions.

	* Analysis/Histogram1D.h: Implemented the normalize function.

2006-11-16  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/LWHFactory.h, Analysis/LWHFactory.cc,
	Analysis/FactoryBase.h: Added abstract normalize* functions to be
	implemented in subclasses. Implementation in LWHFactory not ready.

	* Analysis/Histogram1D.h: Added normalize function. Not
	implemented.

2006-11-15  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/LesHouchesReader.*: Added member variable maxFactor
	to keep track of how much the maximum cross section has been
	increased by increaseMaxXSec().

	* LesHouches/LesHouchesReader.cc: Fixed memory leak where a
	SubProcess object was created with new instead of new_ptr.

	* LesHouches/LesHouchesEventHandler.cc: If weighted events, do not
	generate events with weight 0.

	* LesHouches/MadGraphReader.cc: Added tags for mixed minimum mass
	cuts anticipating a future change in the MadGraph event files.

2006-11-14  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/LesHouchesReader.*: Added member variable lastweight
	to be used when a LesHouchesReader produces unweighted events, but
	these are reweighted. Before all these events reported unit weight
	even if they were reweighted. The lastweight variable is now added
	to the cache file together with the standard Les Houches common
	block. Added member variable skipping to be set when skip() is
	running to avoid unnecessary reweighting of events which will
	never be used. When writing an event to a cache file the CKKW
	reweighting is not performed, instead theis reweighting is done
	when an event is read in again.

2006-11-10  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/MadGraphReader.cc: Trying to keep up with the
	constantly changing fileformat of MadGraph.

	* MatrixElement/MEBase.icc, MatrixElement/MEBase.h,
	MatrixElement/MEBase.cc, LesHouches/LesHouchesReader.cc,
	LesHouches/LesHouchesReader.icc, LesHouches/LesHouchesReader.h:
	Added variables and interfaces for the minimum and maximum
	multiplicity to be considered in a CKKW reweighting procedure.

	* LesHouches/LesHouchesReader.cc, Handlers/StandardXComb.cc,
	Handlers/CascadeHandler.h, Handlers/CascadeHandler.cc: Changed
	signature of reweightCKKW. It now takes arguments giving the
	minimum and maximum multiplicity to be considered in the CKKW
	reweighting procedure.

	* Handlers/ClusterCollapser.cc: Fixed bug where no colour-singlet
	particles were considered for momentum compensation if no coloured
	particles where present.

	* PDT/Onium3GDecayer.cc, PDT/ColourPairDecayer.cc: Fixed bug where
	the scale of the produced coloured particles were not set.

	* Handlers/EventHandler.*: Added options in ConsistencyLevel
	switch to print out an event if inconsistencies are found.

	* EventRecord/SubProcess.*: Added flag to determine if a
	sub-process has been decayed (handled by a CascadeHandler) to
	avoid that the same sub-process is handled twice.

	* Interface/Switch.cc: Ticket #58. Made error message more clear
	when non-existent option is given.

2006-11-08  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Config/Units.h: Removed MultiplicationTraits and renamed
	BinaryMultiplicationTraits to BinaryOpTraits with typedefs for
	MulT and DivT. Simplified the specializations for complex.

	* Utilities/Math.icc: Make the sign function compare to T()
	instead of 0.

	* Config/ThePEG.h, Helicity/LorentzSpinor.*,
	Helicity/LorentzRSSpinorBar.*, Helicity/LorentzRSSpinor.*,

	CLHEPWrap/ThreeVector.h: Removed MultiplicationTraits and changed
	to BinaryOpTraits.

	* CLHEPWrap/LorentzVector.h: Removed MultiplicationTraits and
	changed to BinaryOpTraits. Added assignment from other, but
	equivalent, classes. Changed +=, -=, + and - operators to allow
	for different but equivalent classes. Changed lightCone functions
	to allow for different but equivalent classes.

	* Config/PhysicalQty.h: Changed -= and comparison operators to
	allow different, but equivalent, classes on either side.

2006-11-01  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* include/Makefile.am : cleaned up include file linking and 
	installation. This fixes a problem with using parallel make

2006-11-01  Peter Richardson  <Peter.Richardson@durham.ac.uk>

	for decayers for which needsFullStep() returns true.

	* Config/algorithm.h: Fixed bug in rrange(const Cont &) function.

	* PDT/Decayer.cc: Added virtual needsFullStep and new decay
	functions to be used by remnant decayers and others which need
	access to the current step for the decay.

2006-10-11  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/PartonExtractor.cc, PDF/PartonBinInstance.cc, PDF/PDFBase.*:
	Changed the unit of PDFBase::flattenScale and its jacobian
	argument from Energy to double. Fixed related bug in
	PDFBase::flattenScale.

2006-10-10  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* EventRecord/ColourLine.cc: Now uses
	ColourBase::remove(Anti)ColourLine functions insted of explicitly
	setting colour lines to null.

	* EventRecord/ColourBase.*: Made setting of (anti)colourLine
	virtual. Also introduced virtual remove(Anti)ColourLine functions.

	* PDT/ParticleData.h: Made addDecayMode and removeDecayMode
	protected.

	* PDT/DecayMode.h: Temprorarily made RemnantData a friend.

2006-10-09  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* EventRecord/Step.cc, EventRecord/ColourSinglet.cc,
	EventRecord/ColourLine.icc: Now uses Particle::hasColourLine() to
	check if particle is connected to a colour line.

	* EventRecord/Particle.h: Added virtual hasColourLine() and
	hasAntiColourLine() to check if a given colour line is
	present. These are now also used instead of 'colourLine() == lin
	constructs.

	* EventRecord/ColourBase.h: Added virtual hasColourLine() and
	hasAntiColourLine() to check if a given colour line is present.

	* EventRecord/MultiColour.*: Added sub-class of ColourBase to be
	used by RemnantParticle and other Particle classes with more
	complicated colour structure which may be connected by several
	(anti-) colour lines.

2006-10-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* EventRecord/RemnantParticle.*, PDT/RemnantDecayer.*,
	PDT/RemnantData.*: Started adding RemnantData and RemnantDecayer
	classes which will be used by the Remnant particle class.

2006-10-06  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/LesHouchesEventHandler.*: Ticket #58. Set new
	LuminosityFunction in the initialization to be able to report on
	energies of incoming beams. If a LuminosityFucntion has already
	been set it will be disregarded (as it in principle has been
	previously).

	* Handlers/LuminosityFunction.*: Ticket #58. Added arguments to
	default constructor to set beam energies. To be used by
	LesHouchesEventHandler.

	* Handlers/EventHandler.h: Ticket #58. Made set function lumiFn
	protected to be used by LesHouchesEventHandler.

2006-10-04  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/EventHandler.cc: Added consistencyCheck function which
	checks charge and energy-momentum conservation. Also added
	interfaces ConsistencyLevel and ConsistencyEpsilon to controll the
	check.

2006-10-04  Nils Lavesson  <nils@thep.lu.se>

	* Utilities/Selector.icc: Fixed a bug in swap

2006-10-04  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* acinclude.m4: Fixed output from AC_SEARCH_CLHEP about which
	environments were set to avoid confusion.

	* Handlers/ClusterCollapser.cc: fixed signed/unsigned warning.

2006-10-03  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* EventRecord/Step.cc, EventRecord/Particle.*: Added arguments to
	the colourNeighbour(bool) and antiColourNeighbour() functions in
	Particle. They now also require an iterator range in which the
	(anti-) colour neighbour is searched for. (Previously the neighbor
	was only searched for in the particles birthStep().

	* Handlers/ClusterCollapser.cc: Don't give up so easily if no
	compensating particles was found in the standard way. Try several
	combinations.

	* *** GLOBAL ***: Merged in relevant changes from the
	RELEASE_BRANCH_1_0.

2006-09-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/SimpleFlavour.cc: Fixed bug in meson codes.

	* PDT/QuarksToHadronsDecayer.cc: Fixed bug giving infinite loop in
	getN() if too little energy available. Instead return minN().

2006-09-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/ClusterCollapser.cc: Fixed bug in momentum reshuffling
	when there was only one particle to shuffle with.

	* MatrixElement/MENCDIS.*: Added MENCDIS class to handle
	neutral-current DIS matrix elements. Not yet usable.

2006-09-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/HistogramFactory.h, Analysis/Axis.h: Minor
	documentation changes.

	* MatrixElement/Tree2toNDiagram.h: The documentation was just
	plain wrong...

2006-09-21  Peter Richardson  <Peter.Richardson@durham.ac.uk>

	* Helicity/SpinInfo.h (Repository): change to order of static and const
	to fix gcc3.2.3 warning

2006-09-18  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* src/Makefile.am: fix for #43, CLHEP now added to RPATH

2006-09-15  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* configure.ac: added -W to default warning level

	* *** GLOBAL ***: fixed remaining -W warnings (mostly unused
	function arguments and some copy constructors that needed the base
	classes initialized)
	
2006-09-14  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Repository.cc, Persistency/PersistentIStream.cc:
	Fixed iterators outside bounds found by David.

2006-09-11  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/Throw.h, StandardModel/StandardModelBase.h,
	MatrixElement/ME2to2QCD.h, MatrixElement/ME2to2Base.h,
	MatrixElement/Amplitude.h, Interface/Switch.h,
	Interface/Parameter.h, Interface/ParVector.h, Helicity/SpinInfo.h,
	Handlers/XComb.h, Handlers/LastXCombInfo.h, Doc/refman.h.in,
	CLHEPWrap/HepMCTraits.h, CLHEPWrap/HepMCConverter.h,
	Analysis/VariAxis.h, Analysis/Tree.h, acinclude.m4, README:
	Updated documentation. Mainly to avoid warnings with Doxygen v
	1.4.6.

2006-09-11  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Helicity/*.h : Removed library() lines for non-module classes

2006-09-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/UtilityBase.*: Added boostToCM(), getBoostToCM() and
	getBoostFromCM() taking Triplet arguments.

	* EventRecord/ParticleTraits.h: Added partial specialization for
	pointer to anything.

2006-09-06  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/Makefile.am: Removed FixedCMSLuminosity from the main
	library, since this class is now in a separate module.

	* Handlers/ClusterCollapser.h: Removed the library() function from
	the ClassTraits, since this class is included in the main library.

2006-09-06  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* LesHouches/MadGraphReader.cc, Handlers/SimpleFlavour.h: fixes
	for compile warnings

2006-09-05  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* acinclude.m4, configure.ac, */Makefile.am,
	Config/Makefile.aminclude: The libtool -version-info numbers are
	now controlled from the configure.ac. Also added an include file
	with common targets for the Makefiles.

2006-09-04  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/LesHouchesEventHandler.cc: Fixed bug when
	compensating for underestimated maximum.

	* PDF/LHAPDF.cc: Changing setting of nset so that two LHAPDF
	objects which use the same set will get the same nset. This avoids
	unnecessary and time consuming reinitialization.

	* LesHouches/LesHouchesReader.cc: When creating LHAPDF pdf to get
	the generated pdf values, make sure the values are frozen outside
	the x,Q2 limits to avoid problems if reweighting is requested..

	* LesHouches/LesHouchesFileReader.cc: Fixed setting of XPDWUP to
	zero for each event.

	* PDF/LHAPDF.cc: Fixed units of Q2Min and Q2Max in persistent I/O.

2006-09-03  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/EventGenerator.cc: Fixed bug when writing out progrss
	with tic() function.

	* PDF/PartonExtractor.cc: Fixed bug in constructRemnants()
	functions introduced when changing the boosts (se 2006-09-01).

	* LesHouches/MadGraphReader.*: I think MadGraph uses XMAXUP and
	XWGTUP wrongly. Now increase both by a suitable factor to make the
	cross section add up the way I think it should.

	* LesHouches/LesHouchesReader.*: Modified the setup of statistics
	in case of several processes in one reader. Consequently also
	modified the increaseMaxXSec() function. Still not sure this will
	do exactly the right thing.

	* LesHouches/LesHouchesFileReader.cc: Now sets weighting strategy
	depending on the standard IDWTUP variable.

	* Config/Makefile.aminclude: Added include file to Makefile.am's
	to simplify recompiling certain files with debugging, but without
	optimization.

2006-09-01  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/ThePEGDefaults.in: Added /LesHouches directory with a half
	built EventGenerator with a LesHouchesEventHandler.

	* src/TestLHAPDF.h, Utilities/UtilityBase.h, PDF/LHAPDF.h,
	LesHouches/LesHouchesReader.h: Fixed some documentation bugs.

	* PDF/PartonExtractor.cc: When boosting the hard sub-system to
	transfer a small pt-kick from the remnants, an unphysical
	theta-rotation in case the hard subsystem had rapidity close to
	zero. This is due to a problem with the
	Utilities::transformToMomentum function. PartonExtractor now no
	longer use the transformToMomentum function. Although
	transformToMomentum correctly does what it claims to do, it should
	probably not be used, and it will be removed in the future.

	* Utilities/UtilityBase.tcc: Using the rotations returned from the
	transform to/from CMS functions could before introduce random
	phi-rotations when the vector to be rotated to/from the z-axis was
	already along the z-axis but lack of precision gave a random
	phi-angle. This has now been fixed.

2006-08-30  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/Makefile.am: Make sure the ../lib/ThePEGDefaults.rpo link is
	touched so that other packaged are remade if needed.

2006-08-29  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/FixedCMSLuminosity.*, Handlers/LuminosityFunction.*: To
	facilitate the implementation of HEPML steering in RivetGun the
	base class now handle the setting of individual (maximum) beam
	energies and is able to produce the corresponing beams. This makes
	the FixedCMSLuminosity superfluous and will be completely soon
	removed.

	* Interface/Switch.cc: Fixed "set" method so that giving the name
	of the switch option works. Also "true" and "false" are allowed as
	synonyms for 1 and 0.

	* LesHouches/MadGraphReader.cc,
	LesHouches/LesHouchesFileReader.cc: LesHouchesFileReader now
	implements open() and doReadEvent() to check if the file is a
	standard Les Houches event file format in which case it is read
	accordingly. MadGraphReader is changed accordingly. This is not
	yet tested.

	* LesHouches/LesHouches.*: Added resize functions.

	* Utilities/StringUtils.*: Added function xmlAttributes to scan a
	string for attributes of a given tag assuming we have valid XML
	code in the string.

2006-08-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/LHAPDF.*, PDF/LHAIndex.txt: Index file now also includes (a
	very limited set of) PDFLIB numbers. Added interface to set
	according to PDFLIB numbers. Also removed the variable giving the
	LHAGlue number - the corresponding parameter interface now uses
	set/get methods instead.

	* LesHouches/MadGraphReader.cc: Now uses the LHAGlue numbering to
	specify the PDFs used. Not all sets are implemented though.

	* LesHouches/LesHouchesReader.*: Changed init procedure. More
	checks are done in doinit() rather than initialize(). doinit() now
	optionally rund initPDFs() which created LHAPDF object
	corresponding to the heprup.PDFSUP and heprup.PDFGUP numbers.

2006-08-24  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/UtilityBase.tcc: Fixed bug in getBoostFromCM() where
	the phi-rotation was erroneously performed before the
	theta-rotation.

2006-08-23  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/runEventLoop.cc, src/Makefile.am, CLHEPWrap/Makefile.am,
	CLHEPWrap/GenEventConverter.*: The new HepMCConverter class now
	seems to work both with HepMC in CLHEP and the new stand-alone
	HepMC version 2. The runEventLoop.cc example now uses the
	stand-alone HepMC. The old GenEventConverter class is now
	permanently removed.

2006-08-16  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/EventGenerator.cc, Interface/Interfaced.h: Fixed
	preinitRegister() function so that theGenerator is properly
	set. This required EventGenerator to be a friend of Interfaced.

2006-08-16  Peter Richardson <Peter.Richardson@durham.ac.uk>

	* Cuts/V2LeptonsCut.cc (Repository): change so that maxS() returns
	a large value if not a lepton pair rather than zero

2006-08-15  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/EventGenerator.cc: Fixed getParticleData() so that it
	works also if theQuickParticles has not been initialized.

	* Interface/Reference.cc, Interface/RefVector.cc: Changed exec
	methods so that set and insert now looks for the object to be
	set/inserted in the current EventGenerator rather than in the
	Repository in the pre-init phase of the initialization of an
	EventGenerator.

	* Repository/EventGenerator.cc: Properly register decay modes in
	the current EventGenerator in constructDecayMode().

2006-08-14  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/Tree.h, Analysis/FactoryBase.cc: Fixed segfault when
	creating two histograms with the same path. Now throws an
	exception instead (should be made cleaner in the future).

2006-08-10  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/LHAPDF.cc: Now calls setMinMax() in the doinit()
	function. Also clears the stream in openLHAIndex() if a call to
	open fails.

2006-08-09  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Repository.cc, Repository/EventGenerator.cc: Moved
	the forced update() of all objects from Repository::makeRun() to
	EventGenerator::setup() to make sure that all objects are
	available in the EventGenerator when thay are updated. Before the
	MatcherBase objects were not properly initialized.

2006-08-09  Pete's account  <Peter.Richardson@durham.ac.uk>

	* Repository/Repository.cc (Repository): fix to ensure Matchers correctly setup

2006-08-09  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Cuts/Cuts.cc: Ticket #48: Fixed bug where maxS always returned
	zero.

2006-08-08  Peter Richardson  <Peter.Richardson@durham.ac.uk>

	* Cuts/Cuts.cc: Fix to correctly used the MultiCuts objects
	when testing if a phase-space point passes the cuts.

2006-08-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/PDFBase.xh: PDFRange exception class now inherits from
	Exception rather than from InterfaceException.  +

	* PDF/LHAPDF.*: It is now possible to set the PDF by number rather
	than by file name and member. Using the index file it is now also
	possible to check x and Q2 ranges before calling the LHAPDF
	library, so that we can use our own strategy.

	* PDF/LHAIndex.txt: Added index file to correlate PDF numbers,
	members and file names in LHAPDF. Hopefully this will be obsoleted
	in future versions of LHAPDF.

	* LesHouches/MadGraphReader.*: Modified slightly the creation of
	cut objects in the intialization.

	* LesHouches/LesHouchesReader.cc: Fixed check if theCuts was set
	to avoid segmentation fault.

	* LesHouches/LesHouchesReader.*: Started adding functions to
	create PDFin objects in the initialization (variable doInitPFDs,
	functions preInitialize() and initPDFs() and doini()).

	* LesHouches/MadGraphReader.cc, LesHouches/LesHouchesReader.cc,
	LesHouches/LesHouchesEventHandler.cc, LesHouches/LesHouches.*:
	Fixed typo NRUP -> NPRUP

	* acinclude.m4: Changed AC_FC_LIBRARY_LDFLAGS to
	AC_F77_LIBRARY_LDFLAGS and FCLIBS to FLIBS since the former had
	problems with linking the 'main' function several times if
	gfortran was installed.

2006-07-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* LesHouches/MadGraphReader.*: Introduced InitCuts Switch. If set
	the MadGraphReader will be pre-initialized and will extract cut
	information from the event file and construct and add the relevant
	cuts objects. Not tested.

	* LesHouches/LesHouchesEventHandler.cc: Now uses Throw class for
	some exceptions.

	* Repository/EventGenerator.cc: Modified printout of exception if
	something was thrown in the initialization.

	* Repository/EventGenerator.*: Added preprintRegister() to
	introduce new objects in the pre-init phase (similar to
	preinitCreate(), but the calling function creates the object
	itself.

	* Utilities/Throw.h, Utilities/Makefile.am, Utilities/Exception.h:
	Added Throw class to facilitate the thowing of Exception
	objects. An embryo of this class was before in
	Utilities/Exception.h but has been removed.

	* src/Makefile.am: Added valgrind target to do memory checks.

2006-07-27  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* java/RunFrame.java: Now uses '--tics' option for runThePEG.

	* src/runThePEG.cc: Added '--seed' and '--tics' options which
	eventually will replace the '-seed' and '-tics' ones.

	* PDT/MatcherBase.h: Made pointers in sets of ParticleData and
	ParticleMatcher transient to avoid circular dependence on
	reference counted pointers.

	* PDF/LeptonLeptonRemnant.h: Made pointer to photon object
	transient to avoid possible circular dependence on reference
	counted pointers.

	* Handlers/XComb.h: Made pointers to PartonExtractor and Cuts
	transient to avoid circular dependence on reference counted
	pointers.

	* Handlers/StandardXComb.h: Made pointer to SubProcessHandler
	transient to avoid circular dependence on reference counted
	pointers.

2006-07-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/EventGenerator.h: Changed the behavior of the
	doinit() function so that objects which returns true from their
	preInitialize() function are initialized first in a special
	pre-initialization phase. In this phase the initialized objects
	may use some special preinit functions to add new objects
	(using eg. preinitCreate()) to the run, or manipulate the
	interfaces of the ones which are there (using eg.
	preinitInterface()). Note that this functionality has not been
	proprtly tested yet - it does compile though...

	* PDT/ParticleData.h, PDT/DecayMode.h: EventGenerator is now a
	friend.

	* Interface/InterfacedBase.h: EventGenerator is now a friend.
	Added member function state() which returns the initialization
	state of an object. Added virtual member function preInitialize()
	which by default returns false. If it returns true for an object
	this will be handled first in the initialization of an Event
	handler in a special pre-initialization step. In this case the
	object may use the special 'preinit' functions in the
	EventGenerator when executing its doinit() function.

2006-07-25  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* CLHEPWrap/HepMCConverter.*, CLHEPWrap/HepMCTraits.h,
	CLHEPWrap/Makefile.am, src/runEventLoop.cc, src/Makefile.am:
	Rewrote the GenEventConverter to be completely templated and
	independent on which HepMC version is used. The new class is
	called HepMCConverter and uses the HepMCTraits class for all
	interactions with the HepMC classes. Different flavours of HepMC
	may need to specialize the HepMCTraits class in different ways. By
	inheriting from HepMCTraitsBase you will automatically get the
	interface to the HepMC version in CLHEP. In src/runEventLoop.cc
	(which is now included in the distribution) there is an example of
	how to use HepMCConverter. runPartial.cc is no longer included in
	the distribution.

	* PDF/LHAPDF.*: the interface to the LHAPDF library can now be
	compiled, set up and run, and seems to give correct results.

	* src/Makefile.am: Fixed minor bug in USELHAPDF conditional.

	* Config/Makefile.am: config.h is no longer included in the
	distribution.

	* include/Makefile.am: Config directory is no longer linked,
	instead it is creates a proper directory and links the individual
	header files. This is because config.h needs to be linked from the
	build directory while the others are linked from the source
	directory. This probably need a better solution.

	* Config/std.h: Now includes <sstream> and imports the
	stringstream classes to the ThePEG namespace.

	* Utilities/sstream.*, Utilities/Timer.cc, Utilities/Makefile.am,
	Utilities/Exception.h, Utilities/Debug.cc, configure.ac,
	MatrixElement/ColourLines.cc, Persistency/PersistentIStream.cc:
	Removed sstream.h wrapper around the old libg++ strstream
	header. ThePEG now assumes that all supported compilers has a
	compliant standard library with a standard <sstream> header.

2006-07-25  Peter Richardson <Peter.Richardson@durham.ac.uk>

	* EventRecord/Step.cc (Repository): Added check to prevent
	double attachment of incoming partons to hadrons and some tests
	to prevent illegal boosts in CLHEP 

2006-07-24  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/TestLHAPDF.*: Added Main class and setup file to test the
	LHAPDF classes.

	* src/ThePEGDefaults.in: Added /LHAPDF directory with token LHAPDF
	object to get doxygen output on the interfaces (this should work
	even if the LHAPDF library is not installed).

	* src/Makefile.am: Added TestLHAPDF test to the check and
	install-check targets, but made it conditional on USELHAPDF.

	* PDF/LHAPDF.cc: Fixed bugs: xfx() and xfvx() had the wrong
	signatures and didn't override the base class virtual functions;
	Forgot to set lastX and lastQ2 to avoid unnecessary calls to the
	LHAPDF library.

	* configure.ac: Added USELHAPDF flag for automake generation of
	Makefiles.

	* PDF/LHAPDF.cc: Removed double implementation of dummy function
	evolvepdfm_().

	* acinclude.m4: Ticket #45. Fixed bug where temporary LIBS
	variable for checking LHAPDF was not reset if check failed.

	* configure.ac, acinclude.m4: Added test to see if the LHAPDF
	library is installed. If so the ThePEG_HAS_LHAPDF is set and both
	libLHAPDF.so and the fortran runtime libraries are included in the
	linking.

	* src/TestLHAPDF.in: File to test LHAPDF class. Not used in 'make
	check' yet.

	* PDF/LHAPDF.*, PDF/Makefile.am: Added class to interface the
	LHAPDF library. Compiles, and the objects can be set up, but have
	not tried to run it. DO NOT USE YET.

2006-07-22  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/SubProcessHandler.h: Declared clone functions
	non-inlined since they weren't.

	* src/setupThePEG.cc: Added --exitonerror option. Also added
	'--init' and '--java' options which eventually will replace the
	'-init' and '-java' arguments.

	* src/Makefile.am: Now uses --exitonerror argument for
	setupThePEG. And long '--init' argument when initializing the
	repository.

	* java/SetupThePEG.java: Now uses long '--java' argument when
	startin setupThePEG.

	* Repository/Repository.*: Added static variable accessible from
	exitOnError() which, if non-zero, will call exit with an error
	code if any error was encountered during read(). Also added a
	command 'EXITONERROR' which sets exitOnError() to one.

	* ACDC/ACDCGen.icc: Fixed bug where allocated primary ACDCGenCell
	objects were not deleted in destructor.

	* Persistency/PersistentIStream.*: Fixed bug where
	InputDescription objects created when reading were not deleted in
	the destructor.

	* StandardModel/StandardModelBase.*: Added access function to get
	a pointer to the CKMBase object.

2006-07-21  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Analysis/Makefile.am: added VariAxis.h to LWHHEADERS

2006-07-20  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/VariAxis.h, Analysis/HistogramFactory.h,
	Analysis/Histogram1D.h, Analysis/FactoryBase.*,
	Analysis/AIHistogramFactory.h: Added a VarAxis class in LWH to
	allow Histogram1D to have variable sized bins. This seems to work,
	although the resulting AIDA XML file is not interpreted properly
	by JAS3.

2006-07-19  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/StandardXComb.cc: Fixed bug where the rapidity reported
	to eg. the Cuts object was reversed. Also fixed bug where the
	"post-cut" checking of the SubProcess was made in the collision
	frame rather than in the SubProcess cm frame.

	* MatrixElement/ME2to2Base.cc: The phase space generation now
	takes into account possible rapidity cuts. Compiles and runs but
	should be tested more.

2006-07-19  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* configure.ac: more automated OS X variable detection didn't
	work, back to previous version	

2006-06-30  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* StandardModel/O1AlphaS.*: flavourThresholds() now returns an
	ordered set of scales. New interface FreezeScale controlls below
	which scale the alpha_S is frozed to avoid divergencies and
	negative coupling. LambdaQCDs() now returns Lambda_0 in the zeroth
	place. The Interface LambdaQCD is now only limited from below.

	* StandardModel/AlphaSBase.icc: The LambdaQCD(unsigned int) now
	also returns Lambda_0 for the case of no active flavours.

2006-06-24  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Repository/EventGenerator.cc: ieve added to copy
	constructor; undefined value was written into the repository

2006-06-15  David Grellscheid  <David.Grellscheid@durham.ac.uk>

	* Repository/EventGenerator.{h,cc}: Added signal handling
	functionality to call finalize() when SIGINT, SIGHUP or SIGTERM are
	received.

	* Analysis/Tree.h, Analysis/Histogram1D.h: Modified flat output to
	have title on the end within quotes in the histogram header and
	chaged the output order of the points to "bin-mean-x", "y",
	"delta-y", "number of entries".

	* include/Makefile.am: All needed subdirectory links are now
	separate targets.

	* Handlers/AnalysisHandler.*: Added function to check if the
	EventGenerator has a histogram factory.

	* Analysis/FactoryBase.*: Added member function to create
	histogram with separate title.

2006-06-12  Peter Richardson  <Peter.Richardson@durham.ac.uk>

	* CLHEPWrap/LorentzRotation.icc: fix to setRotateZ which was rotating
	about y but wasn't used anywhere

	* Handlers/StandardEventHandler.h change to get the right Interfaces in the 
	Doxygen documentation

2006-06-11  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* java/Makefile.am: Changed the name 'thepeg.sh' to 'thepeg' for
	the script which is catually installed, while keeping 'thepeg.sh'
	as name of the script in the local directory.

	* Repository/EventGenerator.cc: Now correctly includes
	FactoryBase.h instead of old HistogramFactory.h

2006-06-07  David  Grellscheid <david.grellscheid@durham.ac.uk>

	* java/Makefile.am: Changed name 'thepeg' to 'thepeg.sh' to avoid
	capitalization clash on OS X. With this, ThePEG works on OS X.

2006-06-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Analysis/FactoryBase.*: Added function cd() to change directory
	in the underlying AIDA::ITree.

	* Analysis/LWHFactory.*, Repository/EventGenerator.*,
	Handlers/AnalysisHandler.*, Analysis/FactoryBase.*: Changed the
	name from HistogramFactory to Factory base to avoid name clash
	with updated LWH.

2006-06-05  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/PartonExtractor.*: The constructRemnants() function now
	throws a veto if remnants could not be created.

	* Utilities/CFileLineReader.h: Added function to enable re-reading
	of the current line.

	* LesHouches/MadGraphReader.cc: Fixed the workaround where
	MadGraph for some reason includes empty lines in the middle of the
	header block.

	Also fixed bug when MadGraph events have been unweighted and we
	before read the wrong number of events.

	Sometimes MadGraph exchanges the colour and anti-colour
	lines. Introduced hack to try to notice this and fix it.

	* LesHouches/LesHouchesEventHandler.cc: Renamed interface
	LesHoushesReaders -> LesHouchesReaders

2006-06-03  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	HistogramFactory associated with it.

	* configure.ac, Makefile.am, include/Makefile.am, lib/Makefile.am:
	Added the Analysis directory.

	* Analysis: Added Analysis directory with the classes
	HistogramFactory, an abstract base class for handling histograms
	using the AIDA interface, and LWHFactory a concrete class
	interfacing the light-weight histogram package LWH which
	implements a small part of the AIDA interface.
	LWH is also included in this directory.
2006-05-22  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* EventRecord/Step.*: Added optional boolean argument for checking
	the consistency of the parents in the Step in templated
	addDecayProducts(Iterator firstParent, Iterator lastParent, tPPtr
	child, bool checkfinal). Default is true, which is also the
	previous behavior.

2006-05-18  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/StandardRandom.cc, Repository/RandomGenerator.cc:
	Make sure the cache is flushed when the random generator is

	* PDF/PartonExtractor.*: Fixed bug by adding argument to internal
	construct method to determine whether the produced remnants need
	boosting.

	* PDF/RemnantHandler.*, PDF/BaryonRemnants.*: Changed name from
	createRemnants to boostRemnants, since that is what the method
	actually does.

	'pure abstract' qualifiers on the doupdate, doinit,
	etc. functions.

	* lib/ThePEG.el: Changed ThePEF-class-files so that the standard
	InterfacedBase virtual functions (doupdate, doinit, ...) are not
	included from start. They can be added afterwards with
	ThePEG-interfaced-decl and ThePEG-interfaced-impl functions.

	* PDT/ParticleData.cc: Fixed bug in stable(bool) function.

2006-02-09  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	objects.

	* LesHouches/LesHouchesReader.*: Still not quite ready with the
	scanPDF() function.

	* Interface/Interfaced.*: Added a defaultInit() function and a
	corresponding Command interface. defaultInit() can be implemented
	by sub-classes to automatically create objects for mandatory
	references. Also introduced reporeg() and setDefaultReference()
	functions to help sub-classes with this.

2006-02-08  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

2006-02-06  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/runThePEG.cc, Repository/EventGenerator.*,
	EventRecord/Particle.cc: Davids bug fixes to the setting of life
	lengths introduced the usage of UseRandom when it wasn't set. I
	had to fix things in the persistentOutput function in Particle and
	let the EventGenerator class be responsible for loading Main
	classes rather than the runThePEG program itself.

	* Repository/EventGenerator.cc: Removed the upper limit for
	MaxErrors altogether. Also did the same for other parameters.

2006-02-05  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	multi-cut objects

	* LesHouches/LesHouchesReader.*: The Cuts interface is now
	nullable.

	than one object with the same name. Also renamed the function
	GetObjectsReferingTo to GetObjectsReferringTo.

2006-02-03  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	Modified according to the changes in XComb.

	* Handlers/StandardXComb.*, Handlers/XComb.*,
	Handlers/LastXCombInfo.*: Instead of just having access to the
	incoming and outgoing partons in the generated sub-process XComb
	now have access to the full SubProcess object if it has been
	provided. LastXCombInfo and Standard XComb has been modified
	accordingly.

	* EventRecord/Collision.cc: Adding a SubProcess, now sets its
	pointer to this collision if none was provided before.

2006-02-01  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* MatrixElement/ReweightBase.*, MatrixElement/ReweightConstant.*,
	MatrixElement/ReweightMinPT.*: Reweighting now only use
	information in the LastXCombInfo. All other functions for setting
	kinematics has been removed. ReweightMinPT was added to the
	makefile and has now a scale parameter.

	* MatrixElement/MEBase.*: Fixed proper initialization of
	LastXCombInfo in ctor. Also introduced functions for returning
	alpha_S and alpha_EM.

	* LesHouches/LesHouchesReader.*: Now inherits from LastXCombInfo,
	and information to (p)reweighting is conveyed with the XComb
	object.

	* Handlers/StandardXComb.*: Changes from XComb. Initialization of
	mePartons still doesn't work...

	* Handlers/XComb.*, Handlers/LastXCombInfo.*: XComb now has
	information of the last alpha_s and alpha_ME. Also moved the
	mePartons() here from StandardXComb and added corresponding
	initialization function.

	* Handlers/CascadeHandler.cc: Fixed proper initialization of
	LastXCombInfo in ctor.

	* LesHouches/LesHouchesReader.*, Handlers/XComb.*,
	Handlers/SubProcessHandler.*, Handlers/StandardXComb.*,

	now works in a simple case, but it probably needs more testing.
	... and I did some more testing and slight modifications. It
	should now be stable.

2006-01-16  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/BaseRepository.cc: Added commands to append
	libraries.

	under MAC OSX, therefore, if THEPEG_DYNAMIC_TYPE_INFO_BUG is
	defined, they are now instead indexed by the name() function of
	the type_info object.

2005-06-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	there, but will be removed shortly.

	* LesHouches/LesHouchesEventHandler.cc: Added warnings about
	oversampling in the statistics() function.

	* MatrixElement/MEBase.h: (David Grellscheid) Now includes

2005-04-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/LastXCombInfo.h: Included PDF.h instead of PDF.fh,
	since gcc-4 insists on trying to compile a templated function even
	though it is not used.

	* Persistency/PersistentOStream.icc: Workaround for gcc-4
	defining tYes and tNo in a strange way.

2005-04-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	singlets in map by introducing a static insert() method.

	* Pointer/RCPtr.*: Renamed member thePointer to ptr to avoid
	excessive finger work during debug.

	* MatrixElement/*, Handlers/*: Completed the division between the
	general XComb base class and the StandardXComb class used for the
	sub-process generation in the StandardEventHandler. Changed the
	behavior of LastXCombInfo so that it is templated on possible
	sub-classes of XComb.

2005-04-06  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/FixedSizeAllocator.h: Added include of <memory>.

	prepare for new EventHandler hierarchy.

2005-03-31  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* ACDC/ACDCGen.*: Changed the procedure for presampling. The
	initial basic level is set to the minimum sampling, but is never
	allowed to be less than a fraction (by default 1/nTry()) of the
	maximum sampling.

	* Handlers/ACDCSampler.*: Added a hint in the warning issued if a
	run ends while ACDC is in compensating mode, also made it a proper
	warning. Increased the default number of pre-samplings from 100 to
	1000.

2005-03-10  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* MatrixElement/ME2to2Base.cc: Fixed bug in calculatio of jacobian
	spotted by David Grellscheid. Only showed up if outgoing partons
	were produced close to rest in which case the jacobian diverged.

2005-02-23  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* *** GLOBAL ***: CurrentGenerator to OldCurrentGenerator, EGPtr
	to OEGPtr and EHPtr to OEHPtr to prepare for new EventHandler
	hierarchy.

	prepare for new EventHandler hierarchy.

2005-02-20  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/EventHandler.*: Modified EventHandler according to new
	hierarchy. Also made minor changes to other classes to make it

	'*** OldEventHandler ATTENTION ***'.

2005-02-19  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* *** GLOBAL ***: Renamed EventHandler to OldEventHandler to
	prepare for new EventHandler hierarchy.

2005-02-08  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* lib/fixCLHEP: Copy libCLHEP.so rather than soft link since the
	CLHEP versioning system for shared libraries doesn't really work.

2005-01-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/StandardXComb.*, PDF/PartonExtractor.h,
	MatrixElement/MEBase.cc, Handlers/LastXCombInfo.h,
	Handlers/CollisionHandler.cc, Handlers/XComb.*: Changed slightly
	the interface for XComb, preparing for makeing it a base class
	with StandardXComb as a sub class implementing the standard
	ThePEG-specific sub process generation parts of XComb.

2004-12-30  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/StringUtils.*: Added stripws() function to strip a
	string from leading and trailing white space.

	Init as these should now work properly on any compiler.

	* lib/ThePEG.el (ThePEG-parameter): Made specialization for
	string.

	* Interface/Parameter.*: Made (partial) specialization for string
	parameters to avoid min/max functions and units.

2004-10-13  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/BaseRepository.cc, Interface/InterfacedBase.*: Each
	interfaced object may now be assignrd a unique comment. If an
	interfaced object is being initialized with the setup command in
	the repository the non-virtual InterfacedBase::setup() function is
	called which in turn calls the virtual readSetup(). Everything in
	the stream supplied as argument which is not parsed by the
	readSetup functions will be treated as a comment.

	* Repository/Repository.cc: Added possibility in read() function
	to have continuation lines. If a command line end with a \
	the next line will be added.

2004-09-30  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* lib/ThePEG.el: Added ThePEG-variable-cutnpaste function to
	produce templates for including a variable definition and

	I/O.

2004-09-29  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* lib/ThePEG.el: Added ThePEG-refvector and ThePEG-parvector
	functions.

	* LesHouches/LesHouchesEventHandler.*: Added subclass to
	EventHandler for the LesHouches readers. A reorganization of
	(Partial)Collision/Event handlers is called for.

2004-09-25  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* configure.in, Config/config.h.in, Utilities/CFileLineReader.cc:
	Added facilities to handle .bz2 files as well as .gz files.

	* EventRecord/Particle.icc: Reset pointer to particle
	representation and particle data for the case a dangling pointer
	to the destroyed object should be used accidentally.

	* EventRecord/Step.*: Changed destructor to reset transient
	pointers in Particlespointing to the destroyed object.

	* EventRecord/Collision.*: Changed destructor to reset transient
	pointers in Steps and SubProcesses pointing to the destroyed

	pointers in Collisions pointing to the destroyed object.

2004-07-20  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/PartialCollisionHandler.cc: In performStep, if the
	StepHandler throws an exception, call popStep() to set the correct
	current step rather than calling Collision::popStep() directly.

	* Helicity (directory): Modified to use new documentation format.

2004-07-16  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers (directory): Modified to use new documentation format.

2004-06-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	functions. Before they called the HandlerBase versions, now they
	correctly call the StepHandler ones.

	* Doc/Makefile, Makefile: Also make clean in Doc directory.

	* Handlers (directory): Modified to use new documentation format.

2004-06-25  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	format.

2004-06-23  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* ACDC, CLHEPWrap, Config, Persistency, Pointer, Utilities
	(directory): Modified to use new documentation format.

2004-06-22  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/ParticleData.o: Changed the internal representation of the
	width cut to one upper and one lower cut. Added corresponding
	access functions and Parameter interfaces. Also changed the
	massMax and massMin functions accordingly. The old set and get
	functions for the width cut now sets both the upper and lower cut
	and returns the maximum of the two.

2004-05-14  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/EventHandler.cc: Added doinitrun implementation to
	reset the statistics for the XCombs after initializing the phase

	* LesHouches/LesHouchesFileReader.*: New class.

	* Config/config.h.in, configure.in: Added macros for opening
	compressed files with popen. (popen turns out not to be in the C++
	standard, so we may have to look for another solution).

2004-04-23  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* configure.in: Changed default optimization flag to -O2
	(otherwise things get slow with gcc 3.4.0).

	* ThePEG: The following changes were made to allow compilation
	with gcc 3.4.0.

	* Utilities/TypeInfo.icc: in version and name method, use typeid
	of type rather than variabe.

	* Utilities/Interval.icc: Fixed obvious bugs in check and
	checkAll.

	* Utilities/FixedSizeAllocator.h: Fixed obvious bug in destroy
	which for unknown reasons was not detected before.

	* Utilities/ClassDescription.tcc: Workaround of bug in gcc 3.4.0
	when taking typeid of template parameter.

	* Utilities/ClassDescription.icc: Added scope resolutions to calls
	to name().

	* Repository/Repository.cc: Removed 'template' prefix in calls to
	templated static member functions.

	* Repository/RandomGenerator.icc, Repository/RandomGenerator.h:
	changed return type for rnd(OutputIterator, size_type n) to void.

	* Pointer/RCPtr.icc: Made implementations of swap explicit instead
	of using std::swap (problems with gcc 3.4.0).

	* Interface/Switch.tcc, Interface/Reference.tcc,
	Interface/RefVector.tcc, Interface/Parameter.tcc,
	Interface/ParVector.tcc: Added scope resolution to calls to
	readOnly, limited, and dependencySafe functions.

	* Interface/InterfacedBase.h: Made clear and reset functions
	public.

	* Interface/Switch.cc, Interface/Reference.cc,
	Interface/RefVector.cc, Interface/Parameter.cc,
	Interface/ParVector.cc, Interface/Command.cc: Moved include of
	InterfacedBase.h

	* Handlers/HandlerGroup.tcc: Added #include of Hint.h

	* Handlers/ClusterCollapser.cc: Changes call to swap for PPtr.

	* EventRecord/Particle.h: Made inner class ParticleRep public as a
	quick fix to allow access.

	EventRecord/SubProcess.cc, EventRecord/Step.cc,
	EventRecord/Particle.cc, EventRecord/Event.cc,
	Config/Containers.cc: Removed unnecessary semi-colons.

2004-04-20  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* lib/ThePEG.el: ThePEG-class-files now also create a suitable .fh
	file which is included in the .h file

	interface.

2004-04-17  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	check methods for induvidual cuts for consistency reasons.

	* Handlers/KinematicalCuts.icc: Changed the methods mHat, sHat,
	pTHat, yStar, maxY, minY, maxEta, minEta. The treatment of <
	vs. <= is now better. See documentation for respective functions.

2004-03-31  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Persistency/PersistentOStream.cc: Minor changes to facilitate
	debugging.

	* Handlers/XComb.h, Handlers/CollisionHandler.cc,
	PDF/PartonExtractor.cc, PDF/PartonBin.*: The incoming PartonBin is
	now a transient pointer while the outgoing ones are reference
	counted (before it was vice versa). This is to avoid that outgoing
	PartonBins which are not used get deleted while the transient
	pointers are still around. Also the PartonExtractor was changed to
	reflect this change. In PartonExtractor::getPartons the bins
	corresponding to the incoming particles are also saved last in the
	returned vector to avoid them being deleted. This is then also
	taken care of in CollisionHandler::initialize.In addition, the
	XComb objects now also hold reference counted pointers to the bins
	corresponding to the incoming particles.

2004-03-27  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Helicity/HelicityDefinitions.h: Removed the

	templated.

	* Helicity (Module): Changed the implementation of Direc
	representation in Lorentz spinors. Also fixed documentation.

2004-03-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Helicity (Module): Changed all 'cerr' error messges to
	HelicityLogicalError and HelicityConsistencyError exceptions.

2004-03-04  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Helicity (Module): The helicity classes are now included in the
	ThePEG structure. They have not been tested in this structure yet,
	but it compiles and links into ThePEG without any problems.

2004-03-03  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Helicity (Module): Added Peters helicity classes and started to
	integrate them into ThePEG.

	* MatrixElement/MEBase.cc (Module): Added new virtual function
	constructVertes for constructing the spin information for the

	MEBase::constructVertex in the construct method.

	* EventRecord/Particle.cc (Module): Fixed bug in the cloning of
	the spin information in the ParticleRep copy-tor.

	list of children and also remove this from the childs list of
	parents.

2003-11-19  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* lib/ThePEG.el: Made sure ClassTraits.h is included before class
	traits templates are specialized.

	* configure.in, Config/Makefile.common.in: Made configure steer
	all compiler flags and included info for --help option. Also
	changed the check for log1p and expm1 which caused problems under
	cygwin. Need to also fix a atanh check but no solution to that for
	cygwin yet.

2003-11-04  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* lib/Makefile, lib/fixCLHEP: If CLHEP is already in a dynamic
	library, make symbolic links to the corresponding files instead of
	copying. Also make symbolic links when installing.

2003-11-02  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Makefile: Fixed dependencies for setup target.

	* configure.in: Fixed strange behavior when --prefix is not
	explicitly used.

2003-10-31  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* lib/fixCLHEP: Since CLHEP-2.0 comes with shared libraries, we
	now look for that before trying to find the static one.

	* Handlers/ACDCSampler.h: Added using namespace ThePEG::Units in
	the ACDCGenerator namespace to be compatible with CLHEP-2.0 and
	earlier versions.

	* Config/Units.h: Added using namespace CLHEP to be
	compatible with CLHEP-2.0 and earlier versions.

	* CLHEPWrap/CLHEP.h: Added an empty CLHEP namespace to be
	compatible with CLHEP-2.0 and earlier versions.

	* ../Makefile: Made distclean a special target since here the
	ThePEG directory has to be cleaned last.

	* configure.in: Set the default CLHEPPATH to $prefix rather than
	hardcoded to /usr/local

2003-10-24  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* StandardModel/StandardModelBase.*: Changed CKM function to check
	if theCKM2Matrix has been generated by the CKM object before
	returning a matrix element.

2003-08-27  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/runThePEG.cc: If -x argument specifies a dynamic library, it
	is assumed to contain a class inheriting from Main and which has a
	static Init() function which runs the event generator instead of
	simply calling the event generators go() function.

2003-08-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Main.*: Added base class for classes implementing a
	main steering routine for running an EventGenerator, in case the
	standard 'go()' function in the EventGenerator is not enough.

	* Handlers/EventHandler.cc: Avoid floating exception in
	atatistics() if no events were generated. Write nice message
	instead.

	* Handlers/ACDCSampler.cc: Avoid floating exception in finish() if
	no events were generated. Write nice message instead.

	* ACDC/ACDCGen.icc: Avoid floating exception in efficiency() if no
	events were generated.

2003-08-13  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/DecayHandler.cc: Use the StepHandler::newStep()
	function.

	* Handlers/ClusterCollapser.h: Changed the signature of the
	collapse() function to take a new step as argument instead of a
	collision handler. Changed the handle method accordingly.

	* EventRecord/Collision.*, Handlers/PartialCollisionHandler.*:
	newStep() now have an optional argument to specify the step
	handler.

	* Handlers/StepHandler.cc: createNewStep now sets the handler to
	this.

2003-08-12  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/V2PPDecayer.cc: Fixed but in reweight() where the parent and
	grand parent momenta were not boosted to the parent cms.

	* PDT/WeakToHadronsDecayer.cc, PDT/V2PPDecayer.cc,
	PDT/OmegaPhi3PiDecayer.cc, PDT/FlatDecayer.*,
	PDT/DalitzDecayer.cc, PDT/Decayer.*: Added utility function
	getChildren(), finalBoost() and setScales() in Decayer to be used
	in subclasses.

	* Utilities/SimplePhaseSpace.tcc: Fixed bug in CMSn. I the case of
	two particles the angles were not properly distributed.

	* src/ThePEGParticles.in, src/ThePEGDefaults.in: Using
	WeakToHadronsDecayer instead of dummies PYDECY42 and
	PYDECY48. Also using DummyDecayer instead of PYDECY51 and PYDECY53

	* PDT/WeakToHadronsDecayer.*: Added class for weak decays of taus,
	charmed and bottom hadrons. Seems to work.

	* PDT/QuarksToHadronsDecayer.cc: Fixed bug where the decay
	products were not boosted to the parents frame. Also made minor
	change tosimplify for the WeakToHadronsDecayer sub class.

	* Makefile: Removed -$(MAKEFLAGS) in recursive calls.

2003-08-08  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Config/Makefile.common.in: Moved macro for THEPEGLIBS from src/Makefile to Config/Makefile.common

	* src/ThePEGParticles.in, src/ThePEGDefaults.in: Using
	QuarksToHadronsDecayer also instead of dummies PYDECY11 and
	PYDECY12. Also using ColourPairDecayer instead of dummy PYDECY32.

2003-08-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/ColourPairDecayer.*: Added class inheriting from FlatDecayer
	which can handle colour connected pairs of decay products which
	are to undergo subsequent hadronization and optional
	showereing. NOT TESTED.

	* PDT/QuarksToHadronsDecayer.cc: Class now can handle matcher
	specifications of light quark pairs.

	* PDT/FlatDecayer.*: Added virtual getChildren() functions for
	sub-classes which need to do special things with the children.

2003-08-04  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/ThePEGParticles.in, src/ThePEGDefaults.in: Using
	QuarksToHadronsDecayer instead of dummy PYDECY13.

	* PDT/QuarksToHadronsDecayer.cc: Fixed vaious bugs. Seems to work
	now, but physics not tested.

	* Handlers/SimpleFlavour.cc: Fixed bug in generateHadron() when
	argument was anti-quark and and in setProbabilities() for diquark
	production. Fixed anti-particle bug in vectorMeson() and
	pseudoScalarMeson(). THe class seems to work now but physics not
	tested.

	* Handlers/FlavourGenerator.cc: Just changed error messages.

2003-08-01  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/FlavourGenerator.*: Added 'always' wrapper functions
	which call the virtual generateHadron(), getHadron() and
	getBaryon() functions which throws exceptions if no hadron could
	be generated.

2003-07-30  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/QuarksToHadronsDecayer.*: Added class for decay of particles
	to quarks which are then converted to hadrons distributed
	according to phase space. Not ready yet.

	* PDT/StandardMatchers.h: Added QuarkMatcher.

	* src/ThePEGParticles.in, src/ThePEGDefaults.in,
	PDT/Onium3GDecayer.*: Added Onium3GDecayer class for decay of
	spin-1 onia into three gluons or two gluons and a photon. The
	class has not been properly tested.

2003-07-29  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* src/ThePEGDefaults.in: Added a SimpleFlavour object which is
	used by the BaryonRemnants and ClusterCollapser objects.

	* PDT/StandardMatchers.h: Added Check functions taking PDG code
	arguments for the MesonMatcher and BaryonMatcher classes.

	* PDT/PDT.*: Added functions to get the flavour content out of
	hadrons.

	* Handlers/SimpleFlavour.*: Added class to implement simple
	versions of the pure virtual functions of the FlavourGenerator
	class. The model implemented ti s simplified version of the Pythia
	fortran version. (NOT TESTED)

	* Handlers/FlavourGenerator.*: Changed the standard pure virtual
	functions for the FlavourGenerator class to get rid of things that
	were too much related to the Lund string fragmentation stuff.

2003-07-27  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/OmegaPhi3PiDecayer.h: Changed the class name in the class
	description to ThePEG::OmegaPhi3PiDecayer.

	* lib/ThePEG.el: Changed the naming of classes from
	"/{namespace}/{class}" to "{namespace}::{class}".

	* src/ThePEGParticles.in, src/ThePEGDefaults.in: Changed the
	naming of classes from "/{namespace}/{class}" to
	"{namespace}::{class}".

	* Utilities/DescriptionList.cc: The naming of classes in the class
	description has until now been on the form "/{namespace}/{class}"
	In the future it should instead be on the more natural form
	"{namespace}::{class}". Before the new naming scheme is enforced
	class descriptions will be registered in both the old and new
	form.

	* Repository/BaseRepository.*: Added remove(ObjectList) to safely
	remove a set of objects from the repository if no other objects
	are referring to them. The function is used by the "rm"
	command. In addition a new command "rrmdir" was added to remove a
	complete directory with all its objects and sub-directories. (The
	"rmdir" only removes empty directories.)

	* Repository/Repository.*: The "cp" command now treats particles
	separately (copyParticle()). If a particle has an anti-partner
	this is also copied to the same directory. In addition the decay
	modes of both particle and anti-particle will be copied.

	* PDT/DecayMode.cc: in constructDecayMode() it is now the default
	to specify the full name of the decaying particle (rather than
	just the PDGName).

2003-07-26  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* CLHEPWrap/*.fh, CLHEPWrap/*.h: Reordered include paths to
	prepare for next version of CLHEP which will use namespace CLHEP.

2003-07-25  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/DecayMode.*: Added new member variable to remember the order
	in which the decay products were specified. The produceProducts()
	now created particles according to this order.

	* src/ThePEGParticles.*, src/ThePEGDefaults.in,
	PDT/DummyDecayer.*: Added DummyDecayer class for symbolic decay
	channels. It replaces the PYDECYDummy decayer with mode 102.

	* src/ThePEGParticles.*, src/ThePEGDefaults.in,
	PDT/Tau2HadronsDecayer.*: Added class to decay tau to neutrino
	plus hadrons.

	* PDT/OmegaPhi3PiDecayer.cc: 

	* src/ThePEGParticles.in, src/ThePEGDefaults.in,
	PDT/DalitzDecayer.*: Added class to perform Dalitz decays into e+
	e- gamma.

2003-07-24  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/StandardMatchers.h: Added matcher classes for
	PseudoScalarMesons and VectorMesons.

	* src/ThePEGParticles.*, src/ThePEGDefaults.in, PDT/V2PPDecayer.*:
	Added V2PPDecayer class to decay vector mesons to pseudo-scalar
	ones. Will be flat in phase space unless the grand parent is a
	speudoscalar and its only other daughter is a speudo-scalar or a
	photon.

	* Repository/EventGenerator.icc: Added member functions and
	variables to access the current (partial) collision handler and
	the current step handler.

	* Handlers/PartialCollisionHandler.*: addStep() now has default
	null arguments for the step handler and the hint. If the hint is
	null, it is immediately converted to the default hint. If a step
	was added to a given group, the subsequent groups are
	automatically reinitialized.  In continueCollision(), the
	currentCollisionHandler() of the current event generator is set to
	this. In performStep() the currentStepHandler() in the current
	event generator is set to the step handler which is called.

	* Handlers/HandlerGroup.cc: next() will now return immediately for
	an empty group. addPreHandler(), addHint() and addPostHandler()
	now assumes (rightly) that the hint recieved is never null.
	addHint will refill the whole group event if there is the main
	handler is currently executing. I.e it is assumed that someone
	adding a hint to the main handler wants the whole group to be
	redone.

	* EventRecord/Collision.cc: Fixed so that if a perticle is removed
	from the event record its birthStep pointer is set to null.
	Hopefully this will fix the problem that sometimes when a
	generator is dumped (due to an error) a particle is written to a
	persistent stream and then tries to write a no longer existent
	birthStep.

2003-07-23  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDT/OmegaPhi3PiDecayer.*, src/ThePEGDefaults.in,
	src/ThePEGParticles.in: Added OmegaPhi3PiDecayer class to handle
	omega-phi->3pi decays.

	* lib/ThePEG.el: Added ThePEG-Decayer-class-files function.

	* PDT/FlatDecayer.cc: Now uses DecayMode::produceProducts().

	* src/ThePEGParticles.in, PDT/DecayMode.*: The naming of decay
	modes were before such that only the number and types of the decay
	products were important, this meant that it was not possible to
	have both eg. B0 -> c-cbar d-sbar and B0 -> c-sbar d-cbar decay
	modes since they have the same name and same representation.  Now
	the concept of links have been introduced to indicate that decay
	products can be linked together in pairs making two decay modes
	with the same decay products but different linking different. This
	is indicated in the name by an equal sign instead of a comma:
	B0->c=cbar,sbar=d; and B0->c=sbar,cbar=d;

	Also added a produceProducts() function to produce particles from
	the specified decay products, so that linked particles come first
	and consecutively in the returned vector.

2003-07-22  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* CLHEPWrap/Makefile: Added Matrix.h and Matrix.fh to the dist
	files.

	* lib/fixCLHEP: Make sure the fixed .so version of the CLHEP
	library is called libCLHEP.so irrespective of what the original
	CLHEP library was called.

	* MatrixElement/MEQQ2GG.cc, MatrixElement/MEQG2QG.cc: Fixed error
	in specification of intermediate particles (which was compensated
	by a corresponding error in the colour flow).

	* Makefile: Changed the version number to 1.0ab (between alpha and
	beta).

2003-07-21  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* lib/ThePEG.el: Added the parameter and switches functions which
	were forgotten in the move from skeleton.el

2003-07-20  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* EventRecord/Step.*: Added addDecayNoCheck(tPPtr parent, tPPtr
	child) and, addDecayProduct(tPPtr child) to add decay products
	which are already linked with their parents.

2003-07-19  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/RemnantHandler.*, PDF/PartonExtractor.*, PDF/PartonBin.*,
	PDF/PDF.*, PDF/NoRemnants.*, PDF/LeptonLeptonRemnant.*,
	PDF/BaryonRemnants.*, Handlers/XComb.*,
	Handlers/LastXCombInfo.icc, Handlers/CollisionHandler.cc: Removed
	all traces of old strategy involving the PartonBinInfo and
	RemnantInfo classes.

2003-07-16  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/DynamicLoader.cc: Added the current working directory
	as a standard search path. Also added '/' between paths and
	libraries if needed.

	* src/Makefile: Corrected link flags for setup and run programs.

	* Templates/Makefile, lib/Makefile: Moved ThePEG.el and g++dep to
	the lib directory.

	* Repository/EventGenerator.cc: Changed Pythia7 to ThePEG in
	generateReferences().

	* Handlers/StepHandler.cc: The createNewStep() function now
	automatically calles useMe()

	* Handlers/SubProcessHandler.*, Handlers/KinematicalCuts.*,
	Handlers/EventHandler.*, Handlers/CollisionHandler.*,
	Handlers/AnalysisHandler.*: Added fullclone() method to avoid
	slicing when making copies in the Repository.

	* Config/Makefile, Config/Makefile.common.in: Fixed correct
	include path for installed makefiles.

	* Makefile:  install now depends on the check target to ensure the
	setup and run programs are compiled.

	* ../configure: Added top-level configure script which simply runs
	configure in the sub-directories.

2003-07-14  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Config/Makefile: Removed config.h from DISTFILES.

	* Utilities/SimplePhaseSpace.cc: CMSn now throws
	ImpossibleKinematics if an infinite boost is requested.

	* Utilities/UtilityBase.*: Added new setMomentum function which
	doesn't boost to cms but just rotates to z-axis boosts along it
	and rotates to correct angle.

	* PDT/FlatDecayer.cc: Fixed precision problems for large boosts of
	decay products.

2003-07-13  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Config/Makefile.install: This file is copied to the lib dir in
	the installation and can be used to compile a users own .so
	modules.

	* lib/Makefile: The .o files included in libThePEG.so are now
	explicitly listed. The .so files in the listed sub-directories are
	explicitly soft-linked to the lib directory.

	* Config/Makefile.common.in: .o and .so files are no longer
	automatically soft-linked to the lib directory.

2003-07-12  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Templates/ThePEG.el: This elisp file will replace the old
	skeleton.el. The main difference is the renaming of the p7-*
	functions to thepeg-*. Also started to write specialized functions
	to create standard handler classes with templates for the virtual
	functions.

	* EventRecord/Step.cc: In addDecayProduct() remove test to see if
	children are still in the final state.

2003-07-08  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/SimplePhaseSpace.cc: Set the momentum of the first
	particle rather than boosting it to avoid problems with massless
	particles.

	* Makefile: Hid unnecessary output with @.

	* Utilities/UtilityBase.tcc: Fixed imediate returns in case ranges
	of particles is empty. In setMomentum the boost version is only
	tried if the invariant mass squared or the mass is non-negative,
	otherwise the momentum is set directly.

	* Utilities/Exception.cc: Added a debug function to print out a
	range of particles (and summing their momenta).

	* PDT/ParticleData.h: Added produceParticle method which takes a
	Lorentz vector and a mass.

	* PDF/LeptonLeptonRemnant.*: Added parameter to veto photon
	remnants with too small energy fractions. Also the photons mass is
	properly set to zero.

	* Handlers/ClusterCollapser.cc: The procedure to find particles to
	compensate with was changed so that coloured particles are tried
	first and singlets only if the coloured particles were not enough.
	Also required the compensating particles to have a positive
	invariant mass squared to avoid boost problems.

	* EventRecord/ColourSinglet.*: Introduced ColourSingletException
	which is thrown if an inconsistent colour flow is detected.

2003-07-07  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/Exception.cc: Added debug function to print out
	particle.

	* Handlers/ClusterCollapser.cc: Fixed bug for the case where mass
	of compensating particle is 0.

2003-07-05  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/UtilityBase.tcc: Fixed bug in transformToCMS(): boos
	was backward.

	* Utilities/UtilityBase.*: Added transformToMomentum() method.

	* Utilities/SimplePhaseSpace.cc: Fixed potential problem in
	getMagnitude() where impossible kinematics didn't generate an
	exception due to rounding errors.

	* EventRecord/Step.*: Added setCopy method.

	* CLHEPWrap/Transverse.icc: Fixed bug in phi() calculation.

2003-07-04  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/PartonExtractor.cc: Messed around with the newRemnants
	methods.

	* Utilities/ObjectIndexer.icc: Fixed memory leak in
	operator()(Int).

2003-07-03  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/StepHandler.h: Added method and member for getting the
	current step from the collision handler.

	* PDF/PartonExtractor.*: Changed return type on newRemnants method.

	* Utilities/ObjectIndexer.*: Added const method for getting object
	from index without possibility to create corresponding object.

	* EventRecord/Step.*: Added insertCopy method.

2003-07-02  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/PartonBin.*: Added information about outgoing bins in
	addition to the info about the incoming bin.

	* PDF/PartonExtractor.*, Handlers/XComb.*,
	Handlers/CollisionHandler.*: Changed to use PartonBinInstance
	instead of PartonBinInfo.

	* EventRecord/Step.*: Added removeDecayProducts methods.

2003-07-01  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/XComb.cc: Fixed floating underflow problem due to
	uninitialized field in constructor.

2003-06-30  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Handlers/XComb.*: Prepared to use the new PartonBinInstance
	class.

	* PDF/PartonExtractor.*: Prepared to use the new PartonBinInstance
	class.

	* PDF/RemnantHandler.*, PDF/NoRemnants.*,
	PDF/LeptonLeptonRemnant.*, PDF/BaryonRemnants.*: Prepared to use
	the new PartonBinInstance class.

	* PDF/PartonBinInstance.*: Added new class to hold info on parton
	bins. Instead of a PartonBin having a ParonBinInfo to keep
	temporary info, PartonBinInstance keeps a PartonBin together with
	temporary info.

	* CLHEPWrap/Transverse.h: Added units for input/output to streams.

2003-06-28  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* PDF/PartonExtractor.cc: Fixed association beteen partons and
	parton bins for generated sub-processes (used to find PDFs for
	partons).

2003-06-23  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Utilities/ObjectIndexer.*: Added templated class for dynamical
	association between (reference counted) objects and indices.

	* Handlers/StepHandler.*, Handlers/PartialCollisionHandler.cc: In
	preparation for changing the signature of the handle() method i
	StepHandler classes, StepHandler now has a method to return the
	collision handler which made the call to handle(), The
	corresponding member variable is set be the
	PartialCollisionHandler before handle() is called. Also the
	StepHandler class now has its own method to create a new step if
	needed.

	* PDT/FlatDecayer.cc: The scale of all decay products in a decay
	is set to the squared mass of the decaying particle.

	* Handlers/XComb.cc: The scale of all incoming and outgoing
	partons in a sub-process is set to the hard scale.

	* Handlers/DecayHandler.cc: The scale of a particle which has
	decayed is set to zero.

2003-06-16  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* Repository/Repository.cc: Added code so that the load() command
	will look in the ThePEG_INSTALL_PATH for a .rpo file if the given
	filename did not exist.

2003-06-14  Leif Lnnblad  <Leif.Lonnblad@thep.lu.se>

	* First check-in of ThePEG. This is just what was previously
	Pythia7 but stripped from any pythia-specific classes.  Pythia7
	still exists but contains only pythia-specific classes which
	depend on ThePEG.

	Most significant change is that the 'Misc' directory has been
	removed and all classes therin has been moved to the 'Utilities'
	directory. 

	Another change is that 'make check' now only checks the SimpleLEP
	generator since the SimpleLHC generator was indirectly dependent
	on the FlavourGenerator in the pythia string fragmentation classes
	(used in the remnant handling).

	When compiling, the full compiler and link commands are now by
	default replaced by messages such as 'comiling xxx.cc ...' To see
	the full commands use the make-variable SHOWCOMMAND eg. 'make -k
	check SHOWCOMMAND=1'
