Use case 1: developer build (in your local Jython copy)
-------------------------------------------------------
  - call target 'developer-build' (the default for this build.xml)

This build will create directories /build and /dist below basedir.


Use case 2: full build for a release (using svn checkout)
---------------------------------------------------------
  - make sure you have access to the Jython Subversion repository
    (https://jython.svn.sourceforge.net/svnroot/jython/trunk)
  - override svn.main.dir in ant.properties (if necessary)
  - call target 'full-build'

This build will create a working directory named
full_build/${svn.main.dir} at the same level as your local directories
jython, sandbox and installer.  It will contain a big
jython_installer-${jython.version}.jar file suitable for installation.

To build older releases, it may be necessary to use an older
build.xml, too (with the corresponding tag).  For example it is not
possible to build Release_2_2alpha1 with this version of build.xml.

Note on targets
---------------
A subset of the available targets are designed for direct invocation.
Following an ant convention, the callable targets have a description
attribute.  Use ant -p to display these targets.  All other targets
may behave unpredictably if called directly.


Where ant looks for ant.properties 
----------------------------------
  1. in user.home
  2. in the same directory as this build.xml file
The first setting of a property wins. Further settings are ignored.


Actions for a release
---------------------
See http://wiki.python.org/jython/JythonDeveloperGuide/HowToReleaseJython

        	
An example ant.properties file:
-------------------------------

# - zxJDBC
oracle.jar=C:/workspace/HEAD/for_development/bisdevsrv28/jboss/server/infra/lib/ojdbc14.jar
#informix.jar=${basedir}/../externals/external-jars/ifxjdbc.jar

# - option for javac (build.compiler=modern is a global option to use standard jdk 1.5/1.6/1.7)
#build.compiler=modern
#jdk.target.version=1.5
#debug=false
#deprecation=off

# - the svn main directory to build from; only needed for full-build
# This e.g. could be one of:
#   trunk
#   branches/Release_2_2maint
#   tags/Release_2_2rc3
# meaning any directory just above the two directories:
#   /installer
#   /jython
# svn.main.dir defaults to trunk
#svn.main.dir=trunk

# - the revision; only needed for a snapshot full-build
# To create a snapshot build: uncomment the two revision lines, and indicate the correct revision (it has to be a number)
# For 'normal' builds, this defaults to the latest revision on svn.main.dir (HEAD)
#svn.revision=7114
#snapshot.revision=${svn.revision}

# - the directory containing libsvnjavahl-1.dll (on windows) and svnjavahl.jar; only needed for full-build
# how to get these (for windows):
#   - goto http://subversion.tigris.org/servlets/ProjectDocumentList
#   - open the Releases folder
#   - click on the Windows folder
#   - download svn-win32-1.4.6_javahl.zip (or newer)
#   - unzip the .dll and .jar into javahl.dir
javahl.dir=C:/Programme/Subversion/javahl

# - the directory containing the svnant related .jar files; only needed for full-build
# the following .jar files (probably) are needed:
#   - commons-lang-2.0.jar
#   - jakarta-regexp-1.3.jar
#   - svnant.jar
#   - svnClientAdapter.jar
#   - svnjavahl.jar
# how to get these:
#   - goto http://subclipse.tigris.org/servlets/ProjectDocumentList
#   - click on the the svnant folder
#   - download svnant-1.0.0.zip (or newer)
#   - unzip the jar files from the /lib folder to svnant.jar.dir
svnant.jar.dir=${basedir}/../externals/svnant-jars
