1997-12-26  James Youngman  <jay@gnu.org>

	* testutils/realpwd.cc: Minor corrections to a comment.

	* testutils/Makefile.am: Added "user.c" which compiles to "user",
	a utility somewhat similar to "id".

	* tests/admin/users.sh: Added a couple of extra test cases wich
	run prs to make sure that the list of authorised users is
	correctly understood.

	* tests/Makefile.am: Added "large"; another subdirectory
	containing test suites.

	* split.cc: Commented everything out with #if 0; the split()
	function is now a member function of cssc_linebuf.

	* sf-write.cc, sccsfile.h: Changed the linebuf member from
	"cssc_linebuf" to "cssc_linebuf*".

	* sid_list.h: Renamed class _linebuf to cssc_linebuf.  Only
	affects the test code for this module.

	* sf-get.cc, sf-delta.cc: Changed the linebuf member from
	"cssc_linebuf" to "cssc_linebuf*".

	* sf-admin.cc: Modified the order in which users are added and
	deleted from the authorisation list for strict compatibility with
	"real" SCCS (fixes bug reported by Richard Polton
	<richardp@scopic.com>).

	* sccsfile.cc: Changed the linebuf member from "cssc_linebuf" to
	"cssc_linebuf*".  Also that class has been changed to much reduce
	the requirement for casts.

	* pfile.cc: Renamed class _linebuf to cssc_linebuf.  Also removed
	the necessity for some casts.

	* sf-rmdel.cc: Renamed class _linebuf to cssc_linebuf.

	* list.h: Code reformatting (whitespace changes only).

	* linebuf.h: Renamed class _linebuf to cssc_linebuf.  Also removed
	the necessity for some casts.

	* linebuf.cc: Renamed class _linebuf to cssc_linebuf and put the
	split() parsing utility function into this class (instead of it
	being a global function).

	* fileiter.cc: Renamed class _linebuf to cssc_linebuf.

	* delta-table.cc: Added some instances of ASSERT(0 != this).

	* sf-prs.cc: Changed the linebuf member from "cssc_linebuf" to
	"cssc_linebuf*".

	* delta-iterator.cc: Added assertions that the dtbl member is not
	NULL.

	* cssc.h: Removed declaration of split() (it's now a member
	function of cssc_linebuf).

	* sf-get2.cc, sf-get3.cc: Added assertions that the delta table is
	not NULL.

	* show-disp.sh: Show disposition of the CVS-controlled files...

1997-12-19  James Youngman  <jay@gnu.org>

	* sccsdiff.sh.in: Modified version of sccsdiff arrived from
	Richard Polton; took the ideas onboard for a rewrite of sccsdiff.

	* tests/sccsdiff/rap.sh: Added test code for sccsdiff from Richard
	Polton "The Rubber Buccaneer" <richardp@scopic.com>

1997-12-12  James Youngman  <jay@gnu.org>

	* tests/large/admin.sh: Check that we can create SCCS files for
	extremely long G-files.

	* tests/admin/users.sh: *** empty log message ***

1997-12-11  James Youngman  <jay@gnu.org>

	* sf-admin.cc: Fixed bug where "admin -a" adds users in exactly
	the opposite order to that required.

1997-11-30  James Youngman  <jay@gnu.org>

	* dtbl-prepend.cc, sccs-delta.cc:
	Code split out of sccsfile.h and sccsfile.cc.

	* delta.h, delta-table.cc, delta-table.h, delta-iterator.cc,
	delta-iterator.h: Split delta-iterator.cc delta-iterator.h
	delta-table.cc delta-table.h delta.h out of sccsfile.h.

	* sf-write.cc, sf-rmdel.cc, sf-prt.cc, sf-prs.cc, sf-get3.cc,
	sf-get.cc, sf-get2.cc, sf-delta.cc, sf-cdc.cc, sf-add.cc,
	sf-admin.cc, sccsfile.h, sccsfile.cc, prt.cc, rmdel.cc, prs.cc,
	delta.cc, get.cc, configure.in, cdc.cc, Makefile.am, admin.cc:
	Split delta.h, delta-table.h, and delta-iterator.h out of
	sccsfile.h to compartmentalise the dependencies.

	* what.cc: Added retuen statement after call to fail() so that the
	compiler stops warning about missing return statements.

	* what.cc, unget.cc, prt.cc, rmdel.cc, my-getopt.h, prs.cc,
	my-getopt.cc, getopt.cc, getopt.h, get.cc, cdc.cc, delta.cc,
	Makefile.am, admin.cc, ChangeLog: Renamed getopt.* to my-getopt.*
	to avoid conflict with systemhader of the same name.



Sun Nov 30 14:10:45 1997  James Youngman  <jay@gnu.org>

	* my-getopt.h: Renamed getopt.h because it conflicts with the Unix
	include file of the same name.  On some systems (e.g. IRIX),
	<stdio.h> includes <getopt.h>.  Since autoconf required that we
	use the preprocessor flag -I., this meant that our C++ header was
	being included by the C programs in testutils.  Hence they did not
	compile.  

Sun Nov 23 12:05:32 1997  James Youngman  <jay@gnu.org>

	* getopt.cc: small changes to eliminate unuseful dependence on
 	quit.h.

	* what.cc: no longer needs quit.h (and in fact what no longer
	needs quit.o).

	* tests/year-2000: added test scripts for Year-2000 compliance.
	They also cover the whole life of SCCS (1969 -- 2038).

	* sccsdate.cc: We now handle dates without using time_t, so that
	everything works with dates right up to 2068.  sccs_date::now()
	still fails when time_t runs out (Tue Jan 19 03:14:07 2038 on my
	system).

	* mktime.c: removed this obsolete file.

	* configure.in: no longer need mktime() or "timezone".

	* sccsname.cc: Fixed bug with 1-character filenames.

	* mystring.h: Use the standard string class from <string>, if it
	is available.

Thu Nov 20 21:03:24 1997  James Youngman  <jay@gnu.org>

	* sccsdate.cc: Added changes mandated by X/Open for year
	2000 compliance, and fixed year-2019 bug. 

	* docs/cssc.texi: Added chapter covering Year 2000 issues to the
 	manual.

Wed Nov 12 00:13:01 1997  James Youngman  <jay@gnu.org>

	* docs/cssc.texi: added TODO comments for text that still needs to
	be written. 

	* docs/TODO: added list of undocumented/unimplemented/untested
	stuff. 

Tue Nov 11 22:11:47 1997  James Youngman  <jay@gnu.org>

	* strerror.c, strstr.c: #include <config.h> not "cssc.h" since the
 	latter contains C++ class definitions and this is a C module.

	* fsync.h, list.h: Don't use double leading underscores in macro
 	names since this conflicts with the implementation's namespace.

	* file.h: Don't munge the names of rename() and remove() since
 	these now no longer have their definitions #included.

	* Makefile.am: Fixed rule for sccsdiff, which did not work on BSD
 	make (since it didn't grok "$<", apparently).

Sun Nov  9 21:06:59 1997  James Youngman  <jay@gnu.org>

	* NEWS: Changes for CSSC-devel-0.03-pl0.

	* Makefile.am:
	Added in some extra garbage to the distribution so that 99.9% of the
	contents of Master-Source goes into the distribution, even unuseful
	stuff like _chmod.cc.  Someone might want it for a port.  Might move
	it into unused/ soon though.

	* configure.in:
	Changed the package number to restore the "devel" label but
	(apparently) conform to the Gnits standard...

	* Makefile.am:
	Added noinst_HEADERS macro so that the header files get put in the
	distribution too.

	* NEWS: Updated for CSSC-0.02-devel-pl7.

	* configure.in: Package name is "CSSC", not "cssc".

	* README: Removed "xxx does not work" for appropriate values of xxx.

	* strstr.c:
	Can't use LIDENT any more to "rename" strstr() since this file is now
	compiled separately.

	* strstr.c:
	No need to guard against multiple inclusion since this is now compiled
	separately.

	* version.cc.in: Initial revision

	* sf-get.cc, sf-delta.cc, sf-admin.cc:
	Don't include strstrr.cc directly; configure now puts it into
	@LIBOBJS@.

	* acconfig.h:
	Include the macros PACKAGE and VERSION to make autoheader happy.

	* configure.in:
	Switched to using "automake".  Also, the config header file produced
	by "configure" is now called "config.h" (what used to be the old
	"config.h" is now part of "cssc.h").

	* cssc.h:
	Got rid of the old config.h file by including its contents directly
	into cssc.h.  Hence the config header file produced by "configure" is
	now called "config.h".

	* Makefile.am: Initial revision

	* configure.in: Some automake changes.   Doesn't really work yet.

	* cssc.h: Merged the contenst of config.h.

Sat Nov  8 23:09:25 1997  James Youngman  <jay@gnu.org>

	* AUTHORS: Initial revision

Sat Nov  8 14:29:45 1997  James Youngman  <jay@gnu.org>

	* Makefile.in:
	Changes to distclean to make sure we don't include generated files in
	the archive if we "make dist" when the source and object dirs are the
	same.

	* Makefile.in:
	To make life easier for those without a copy of "makeinfo", we supply
	a ready-made info file in the distribution.

Fri Nov  7 23:06:06 1997  James Youngman  <jay@gnu.org>

	* sf-admin.cc: sl-merge.cc is now sl-merge.h.

	* configure.in: Also produce pwd/Makefile.

	* sl-merge.h:
	This is now a .h not a .c file.  It had been #included anyway.

	* sid_list.cc:
	Added in most of what had been in sid_list.cc into sid_list.h; this
	had been #included anyway.  The test code is all that's still left in
	the now much shorter sid_list.cc.

	* sid_list.h:
	Added in most of what had been in sid_list.cc; this had been #included
	anyway.  The test code is still left in the now much shorter
	sid_list.cc.

	* list.h:
	Added in what used to be the contents of list.cc; this had been
	#included anyway.

	* admin.cc: Include sid_list.h and sl-merge.h.

	* Makefile.in:
	Use "distclean" target because it is mentioned in INSTALL.
	Also, added "realpwd" and updated the dependencies.

Thu Nov  6 22:37:22 1997  James Youngman  <jay@gnu.org>

	* config.h, cssc.h, defaults.h, file.h, fileiter.h, filelock.h:
	Don't use preprocessor identifiers beginning with two underscores;
	that conflicts with the implementation's namespace.

	* filepos.h: Protect against multiple inclusion.

	* getopt.h, linebuf.h, list.h, myconfig.h, mystring.h, pfile.h, pipe.h, quit.h, run.h, sccsdate.h, sccsfile.h, sccsname.h, seqstate.h, sf-chkmr.h, sid.h, sid_list.h, stack.h, sysdep.h, xalloc.h:
	Don't use preprocessor identifiers beginning with two underscores;
	that conflicts with the implementation's namespace.

Wed Oct 29 23:01:43 1997  James Youngman  <jay@gnu.org>

	* mkinstalldirs, COPYING: Initial revision

	* Makefile.in:
	FreeBSD's "make" doesn't define "RM" by default.  So provide that
	definition.

Tue Oct 28 22:43:40 1997  James Youngman  <jay@gnu.org>

	* Makefile.in:
	By default, only generate the info file and not the DVI file also.

Mon Oct 27 19:28:00 1997  James Youngman  <jay@gnu.org>

	* sf-get.cc:
	write_subst(): take as a parameter the delta which is actually being
	gotten, so that keyword substitution is correctly carried out.

	* sccsfile.h, sf-admin.cc, sf-delta.cc:
	Use the no_id_keywords() member function to indicate that situation
	(which might result in either a fatal error or just a warning,
	according to the setting of the "i" flag).

	* sf-get2.cc:
	write_subst(): take as a parameter the delta which is actually being
	gotten, so that keyword substitution is correctly carried out.  Also,
	use the no_id_keywords() member function to indicate that situation
	(which might result in either a fatal error or just a warning,
	according to the setting of the "i" flag).

	* Makefile.in:
	Added sf-kw.cc for get, delta and admin.  Also added targets for
	testing each program separately.

	* sf-kw.cc: Take as a parameter the name of the file.

Sun Oct 26 19:48:06 1997  James Youngman  <jay@gnu.org>

	* sf-kw.cc: Initial revision

	* get.cc: The -m and -n options had been the wrong way around.

	* what.cc: Made the output format match that of the real thing.  Most
	importantly, we no longer emit the initial @(#).

Sat Oct 25 16:53:26 1997  James Youngman  <jay@gnu.org>

	* README:
	Modified the example scripts for compiling the package, in such a way
	that I get more information if there is some failure.  Also, update
	the name of the GNU domain; this has changed from gnu.ai.mit.edu to
	gnu.org.

	* Makefile.in: Added canonify.cc to the sources for making "get".

	* sid.h, sid.cc:
	Sometimes we _always_ want the SID component to be printed, even if it
	is zero.  Examples of this include the %R%,%B%,%L% and %S% keywords
	expanded by sccs-get.  An extra argument (with a default) has been
	added to sid::printf().  The default behaviour is the same as the old
	behaviour.

	* sf-get2.cc:
	Corrected the expansions of the %R%, %L%, %B%, %S% and %P% keywords.
	(Also have a new test file, get/subst.sh, to test these).

	* sccsname.h:
	Added prototype for canonify_filename(), which is used in sf-get2.cc,
	to expand the %P% keyword.

	* mystring.h, mystring.cc:
	Added an operator[], which returns a const char&.

	* canonify.cc:
	canonify_filename() now takes a const char* as its argument.

	* canonify.cc: Initial revision

Mon Aug 11 21:35:36 1997  James Youngman  <jay@gnu.org>

	* mystring.h: Patches from Fila Kolodny <fila@ibi.com> to support
 	snapshots of GCC after 2.7.2.2.

Thu Jul 17 08:39:42 1997  James Youngman  <jay@gnu.org>

	* tests/common/test-common: Fixed typo (which had caused echo -e
 	bug on Solaris).

Tue Jul 15 18:59:52 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Bumped patchlevel (Solaris /bin/sh portability).

Tue Jul 15 07:04:02 1997  James Youngman  <jay@gnu.org>

	* Makefile.in:
	Bumped patchlevel (lndir now is happy if source & dest are the same).

Mon Jul 14 21:40:20 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Bumped the version number -- another prerelease, 0.02.

	* Makefile.in:
	Made it possible to run "make dist" from the work dir.  That way, an
	already-created makefile will be used.  No actual files from the work
	directory are included in the distribution.

	* Makefile.in: Make in "lndir" too.

	* configure.in: sub-configure in "lndir" too.

Thu Jul 10 20:31:17 1997  James Youngman  <jay@gnu.org>

	* README: Provided quick-start info and a reference to docs/TESTING.

Thu Jul 10 20:17:31 1997  James Youngman  <jay@gnu.org>

	* sf-prt.cc, sccsfile.h, sccsfile.cc:
	Horrible hack to support "empty" include/exclude lists for deltas so
	that prt can be completely faithful to the SCCS command of the same
	name.

Wed Jul  9 21:59:21 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Bumped to 0.01-devel-pl13.

Mon Jul  7 21:36:15 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Small correction to all-tests target.

	* Makefile.in:
	Don't hardwire $(prefix).  Also rationalised testing targets.

	* run.h:
	Use USE_PIPE not HAVE_PIPE because HAVE_FORK is also required in order
	for USE_PIPE to e sensible.

	* acconfig.h: Add explanation of HAVE_FORK.

	* pipe.h, sf-delta.cc, pipe.cc:
	Use USE_PIPE not HAVE_PIPE because HAVE_FORK is also required in order
	for USE_PIPE to e sensible.

	* configure.in:
	Treak fork() specially since we have to avoid it on AmigaOS.

	* quit.cc:
	Use USE_PIPE not HAVE_PIPE because HAVE_FORK is also required in order
	for USE_PIPE to e sensible.

	* run.cc: Try to cope with the almost-completely-useless semantics of
	system()...MR validation on systems without fork() or spawn() is
	broken.

Wed Jul  2 18:21:52 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Bumped patchlevel (attempted IRIX fix)

Wed Jul  2 18:18:44 1997  James Youngman  <jay@gnu.org>

	* quit.cc, prs.cc, prompt.cc, pipe.cc, pfile.cc, pf-del.cc,
 	pf-add.cc, mystring.cc, list.cc, linebuf.cc, l-split.cc,
 	getopt.cc, get.cc, fsync.cc, fileiter.cc, file.cc, delta.cc,
 	cdc.cc, admin.cc, _chmod.cc:
	Oops.  Removed line that should not have been in the header.

	* xalloc.h, sysdep.h, stack.h, sid_list.h, sid.h, sf-chkmr.h,
 	seqstate.h, sccsname.h, sccsfile.h, sccsdate.h, run.h, release.h,
 	rel_list.h, quit.h, pipe.h, pfile.h, mystring.h, myconfig.h:
	Updated the copyright header.

	* myconfig.h: Initial revision

	* list.h, linebuf.h, getopt.h, filelock.h, fileiter.h, file.h,
 	defaults.h, xalloc.cc, what.cc, unget.cc, strstr.cc, split.cc,
 	sl-merge.cc, sid_list.cc, sid.cc, sf-write.cc, sf-rmdel.cc,
 	sf-prs.cc, sf-get3.cc, sf-get2.cc, sf-get.cc, sf-delta.cc,
 	sf-chkid.cc, sf-cdc.cc, sf-admin.cc, sf-add.cc, sccsname.cc,
 	sccsfile.cc, sccsdate.cc, sact.cc, run.cc, rmdel.cc, rl-merge.cc,
 	rel_list.cc, quit.cc, prs.cc, prompt.cc, pipe.cc, pfile.cc,
 	pf-del.cc, pf-add.cc, mystring.cc, list.cc, linebuf.cc,
 	l-split.cc:
	Updated the copyright header.

	* getopt.cc: Updated the copyright header.
	Also made the class members non-inline to appease IRIX.

	* get.cc, fsync.cc, fileiter.cc, file.cc, delta.cc, cdc.cc,
 	admin.cc, _chmod.cc:
	Updated the copyright header.

	* sf-prt.cc:
	It seems that -b doesn't turn off the printing of the delta table,
	after all.

	* sccsfile.cc, sf-prt.cc:
	Ue SEEK_SET instead of the manifest constant zero for fseek().
	Include <unistd.h> to get it, on SunOS.

	* filepos.h:
	Ue SEEK_SET instead of the manifest constant zero for fseek().

Wed Jul  2 06:55:16 1997  James Youngman  <jay@gnu.org>

	* Makefile.in:
	Portability fixes for Solaris and SunOS; make sure libsubst.a is never
	empty (Solaris ld doesn't like empty libraries), fall back on
	fseek()/ftell() in the absence of fsetpos()/fgetpos().

	* sf-prt.cc:
	Use the helper class FilePosSaver to encapsulate fgetpos() or the lack
	of it.

	* filepos.h: Initial revision

	* configure.in, acconfig.h: Added HAVE_FSETPOS.

	* dummy.cc: Initial revision

Tue Jul  1 07:56:48 1997  James Youngman  <jay@gnu.org>

	* Makefile.in:
	Bumped to patchlevel 10 (we were installing cssc.info in the root
	directory!)

Mon Jun 30 22:15:07 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Bumped to CSSC-0.01-devel-pl9 prior to release.

	* INSTALL:
	Replace the original (MySC) INSTALL file with the generic one suitable
	for Autoconf-generated "configure" files.

	* move-if-change: Initial revision

	* Makefile.in:
	Moved version info into vernum.h, which is an auto-generated file.
	We now avoid re-building version.o and relinking everything, if the
	actual version information is unchanged.   Also support tar'ing the
	RCS files into a separate tar file for possible distribution.

	* version.h: Initial revision

	* version.cc:
	Moved version info into vernum.h, which is an auto-generated file.

	* Makefile.in: Support "make install".

Sun Jun 29 10:47:08 1997  James Youngman  <jay@gnu.org>

	* configure.in: Put the *.cs files into the directory "shorter".

	* Makefile.in: Added "prt" as a target.

Sun Jun 29 09:38:21 1997  James Youngman  <jay@gnu.org>

	* docs/Makefile.in:
	Make PostScript output (A4 by default) too.  Support Letter-sized
	paper as well.

	* docs/gpl.texinfo: Initial revision

	* docs/cssc.texi: Put the copy of the GPL back in.

Sat Jun 28 15:12:58 1997  James Youngman  <jay@gnu.org>

	* docs/cssc.texi:
	MR numbers do not have to be numbers.  Added "Known Problems"
	section.  Added remarks about how to encode files sent with bug
	reports.

Sat Jun 28 14:40:04 1997  James Youngman  <jay@gnu.org>

	* prt.cc: Always print the s.file's name, even of there is only one.

	* sf-prt.cc:
	Several fixes to do with the arrangement of whitespace.  Also, say
	"none" if we have no flags.

Fri Jun 27 18:51:22 1997  James Youngman  <jay@gnu.org>

	* sccsfile.cc: Added next_seqno(), used by delta.

	* sf-delta.cc:
	Working creation of null deltas; this version doesn't break branching
	(in absence of null deltas).

	* sccsfile.h: Added next_seqno(), used by delta.

Mon Jun 23 23:02:47 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Added rl-merge.cc.

	* sid.h: Moved operator release() elsewhere.

	* sid.cc: Moved release::release(const sid&) elsewhere.

	* release.h: Added release(const sid&).

	* sf-delta.cc: Preliminary support for null deltas.

Tue Jun  3 20:23:40 1997  James Youngman  <jay@gnu.org>

	* sccsfile.h:
	Provide sid_in_use(), initially for use by find_next_sid().

	* quit.h, quit.cc:
	Added the function name to the information given when an assertion
	fails, for GCC only.

	* get.cc:
	sccs_file::find_requested_sid() needs to pass back some information if
	the requested sid was either unspecified or specified the release
	number only.

	* sid.h: Added sid::next_level(), initially for use by
	sccs_file::find_next_sid().

	* sf-get2.cc:
	Better support for branching and a stab at support for the joint-edit
	flag.

Mon Jun  2 23:07:11 1997  James Youngman  <jay@gnu.org>

	* sf-get2.cc:
	Reworked find_next_sid(), which decides what SID we'll put in the
	p.file.

Sun Jun  1 20:39:03 1997  James Youngman  <jay@gnu.org>

	* sid.h, sid.cc:
	Provide new methods on_trunk(), matches(), and components(), initially
	for use by sccs_file::find_requested_sid().

	* sf-get2.cc:
	Rewrote get_requested_sid() to be shorter, provide behaviour closer to
	SCCS, and to allow for later support of get's -t option.

	* release.h:
	Provide informational enum member LARGEST, denoting the largest valid
	release number.

	* sccsfile.h:
	Find_requested_sid() needs to know wether it should look along
	branches, so provide that as a parameter.

	* sf-admin.cc:
	The "fixes" for id-keyword processing had accidentally ensured that we
	only read the first line of the input file :-)

	* sccsfile.cc, sccsfile.h: Added sccs_file::delta::removed().

	* sf-get2.cc:
	Correctly handle "get -r99" when there is only one revision in the
	file.

Sun Jun  1 00:36:37 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Bumped the patchlevel to CSSC-0.01-devel-pl6

Sun Jun  1 00:32:11 1997  James Youngman  <jay@gnu.org>

	* Makefile.in: Updated the dependencies.

	* sf-prt.cc: Fixed small bug with empty string flags.

	* release.h: print() needs to return zero for success.

Sat May 31 23:30:27 1997  James Youngman  <jay@gnu.org>

	* sccsfile.cc:
	Support empty 'i', 'x', and 'g' control lines with no argument.   This
	serves no purpose, but these do turn up.

	* sf-prt.cc:
	Support -i (list included/excluded deltas) and the printing of MRs and
	comments (i.e. -d as opposed to -s).

	* sf-prs.cc, sf-get3.cc, sf-get2.cc, prs.cc, get.cc, sccsfile.h:
	Changed variables named "cutoof" to "cutoff_date" to avoid the new
	struct cutoff inside sccs_file.

	* sccsfile.cc:
	Added a version of find_most_recent_sid() that works purely
	chronologically rather thann along a branch.

	* sccsfile.h:
	A version of find_most_recent_sid() that works purely chronologically
	rather thann along a branch, plus support sccs_file::cutoff, a reified
	object encapsulating cutoff dates and SIDs for programs like sccs-prt
	and sccs-prs.

	* sccsdate.h: valid() can be a const member of sccs_date.

	* sf-prt.cc:
	Working support for cutoff dates and SIDs, plus printing the body of
	the file.

	* prt.cc: Working support for -c, -r, -y and also -b (print body).

Sat May 31 10:27:10 1997  James Youngman  <jay@gnu.org>

	* Makefile.in:
	New source files rel_list.cc, rl-merge.cc, and sysnerr.h.  Renamed
	$(LFLAGS) to $(LDFLAGS).

	* sf-delta.cc, sf-get.cc: Fixes for id-keywords-flag processing.

	* quit.cc:
	Obtain declarations of sys_nerr and sys_errlist from our own header
	sysnerr.h, which used macros generated by "configure".

	* admin.cc: Support naked -i, -m, and -y options.  Hence remove
 	the -I, -M, and -Y options.

	* prt.cc: Initial revision

	* sccsfile.cc, sf-write.cc: Fixes for id-keywords-flag processing.

	* release.h: Initial revision

	* sid.h: Reimplemented the class release_list.

	* sf-admin.cc:
	Fixes for id-keywords-flag processing, and support the naked "y"
	option, which inhibits the default comment.

	* sf-get2.cc: Fixes for id-keywords-flag processing.

	* rl-merge.cc, rel_list.h, rel_list.cc: Initial revision

	* sf-prs.cc:
	Fixes for id-keywords-flag processing.  Reimplemented the class
	release_list.

	* sccsfile.h: Support "prt".  Fixed for id-keywords-flag
 	processing.  Use rel_list.h since we have now reimplemented the
 	class release_list.

	* sf-prt.cc: Initial revision

Tue May 27 20:16:39 1997  James Youngman  <jay@gnu.org>

	* sysnerr.h: Initial revision

	* unget.cc: Actually SCCS _doesn't_ print the locked SID twice, I
 	was mistaken :-(

Sun May 25 15:34:00 1997  James Youngman  <jay@gnu.org>

	* unget.cc:
	Modified the output format to be closer to that of SCCS.  We're still
	not there, and the current "unget" test script fails for us (it passes
	for SCCS).

	* fileiter.cc, fileiter.h:
	Added unique() which returns nonzero if we're in the situation where
	the utilities don't need to print out the name of the SCCS file
	they're working on because it's unambiguous -- that is, exactly one
	was specified on the command line.

	* pfile.h:
	Added print_lock_sid, which prints the SID of the lock that "pos"
	refers to (the SID of the delta not the SID of the gotten revision).

	* pfile.cc:
	Added print_lock_sid, which prints the SID of the lock that "pos"
	refers to.

Fri May 23 00:11:28 1997  James Youngman  <jay@gnu.org>

	* Support "admin -t" with no argument.

	* Makefile.in (docs/Makefile): Need installdocs target.

Wed May 21 00:06:46 1997  James Youngman  <jay@gnu.org>

	* linebuf.h, linebuf.cc:
	Small changes (not actually to executable code) to allow the sid_list
	test code to work.

	* sl-merge.cc:
	Much fixing with regard to sid_lists.  Construction from,
	comparison with, and assignment from NULL are sins no longer
	committed.  Also, the nested class "range" is now a separate template
	class.

	* sid.cc:
	The branch and sequence components of trunk revisions are supposed to
	be blank.  Also some small changes (not actually to executable code)
	to allow the sid_list test code to work.

	* getopt.cc:
	Invented the '!' modifier, similar to ':', but allowing empty
	options.  Note that this is to support empty -m and -y options for
	admin and delta, that this behaviour is for compatibility with "real"
	SCCS, and is unlike traditional or POSIX option processing.

Tue May 20 23:58:56 1997  James Youngman  <jay@gnu.org>

	* delta.cc: Support for empty -m and -y options.

	* admin.cc:
	If admin is given a bare -y option, this means that NO comments are to
	be entered into the SCCS file for the initial delta.  This is distinct
	from the situation when no -y option is given, when a "date and
	time created..." entry is added.  Hence the suppress_comments flag
	needs to be passed down into sccs_file::create(), which is where that
	message is normally added.

	* sf-prs.cc:
	Many, many fixes involving the output format for flags that are not
	set, plus backslash escape processing has been implemented, as in
	"real" SCCS.

	* sf-admin.cc:
	If admin is given a bare -y option, this means that NO comments are to
	be entered into the SCCS file for the initial delta.  This is distinct
	from the situation when no -y option is given, when a "date and
	time created..." entry is added.  Hence the suppress_comments flag
	needs to be passed down into sccs_file::create(), which is where that
	message is normally added.

	* sf-write.cc, sccsfile.h:
	Construction from, comparison with, and assignment from NULL are sins
	no longer committed with sid_lists.

	* pfile.h:
	Use range_list<>'s empty() method, not comparison with NULL, to find
	out if it empty.

	* sid_list.cc, sid_list.h:
	Much fixing with regard to validity checks.  Construction from,
	comparison with, and assignment from NULL are sins no longer
	committed.

Mon May 19 18:57:22 1997  James Youngman  <jay@gnu.org>

	* sid_list.h: Eliminate range_list<>::operator=(void*), since it
	is a carbuncle -- see comments in sid_list.h.

Sat May 17 12:19:02 1997  James Youngman  <jay@gnu.org>

	* run.cc:
	If run_mr_checker() is called (because the v flag is set) but the PRG
	argument is empty (i.e. the flag is set to the empty string), the
	validation silently succeeds.

	* delta.cc:
	Fixed bugs involving MRs.  We now output the delta's SID to stdout even
	though the delta fails, because that's what SCCS does.  More
	importantly, if the MR validation flag is set, but has no value, MRs
	are prompted for and allowed (with the -m option) but no actual
	changing is done -- they are always assumed valid.

Fri May 16 08:04:08 1997  James Youngman  <jay@gnu.org>

	* Support tests for MR number processing and interactive comments
	for delta (but the latter is only done if stdin is a tty...)

Thu May 15 21:51:57 1997  James Youngman  <jay@gnu.org>

	* l-split.cc:
	Fixed split_mrs().  It now calls strtok correctly and frees the right
	thing.  I don't see how it could ever have previously worked...but I
	don't know that it did.

Tue May 13 17:40:15 1997  James Youngman  <jay@gnu.org>

	* get.cc:
	Sense of the variable "keywords" was inverted.  We now suppress
	keyword expansion for -e and -k, and do expansion otherwise, not vice
	versa.

Sat May 10 14:50:00 1997  James Youngman  <jay@gnu.org>

	* almost all files: changed the package name

	* version.cc: Modified the version strings so that they show up with
	RCS ident and SCCS/CSSC's what, and also are human-readable.

	* cssc.h: Moved the version() function into version.h.

	* sccsfile.cc: Fixed problem with updating our notion of hogh_release.

	* sf-delta.cc:
	Output the inserted/deleted/unchanged lines, just like "real" SCCS.

	* get.cc:
	Go for output compatibility when reporting Included/Excluded deltas,
	and actually make the output the same.

	* Tested the test scripts themselves against the real thing, and
	hence fixed them, and hence made some changes to CSSC, mostly in
	the exact format of the output (sccsfile.cc, sf-delta.cc, get.cc).

Wed May  7 23:39:49 1997  James Youngman  <jay@gnu.org>

	* sf-get2.cc: find_requested_sid: Fix a bug in the case where
 	there is only one SID (1.1) in the file and no -r is specified on
 	the command line (i.e requested.is_null() is true).

Sun May  4 17:01:36 1997  James Youngman  <jay@gnu.org>

	* sf-get2.cc: Fixed the behaviour when no -r is given or the -r
 	that is given is of the form -rX or -rX.Y.Z (see docs/get-spec.txt
 	and tests/get/sid-select.sh)

	* Makefile.in: Added sccsdiff to $(CMDS).

	* Makefile.in:
	Added a rule for creating sccsdiff.sh from sccsdiff.sh.in.

	* configure.in:
	Find the pr(1) program and substitute for it in sccsdiff.sh.in.

	* file.cc: Corrected usage of freopen(), which returns NULL on failure.

	* sccsdiff.sh.in:
	Have to enclose the version string in single rather than double
	quotes, to protect the dollar signs from shell expansion.

	* sccsdiff.sh.in: Initial revision

Sun May  4 12:11:02 1997  James Youngman  <jay@gnu.org>

	* sf-get2.cc: Bugfix for behaviour with "-e -r2" when latest trunk
	revision was 1.x.  This used to get a delta from 1.x, now it
	creates the new delta 2.1, as does "real" SCCS.

Sat May  3 22:42:55 1997  James Youngman  <jay@gnu.org>

	* get.cc:
	Added support for the -G option (standard and used by, for example,
	GNU make).

	* sf-get2.cc:
	If no SID is specified with -r, and no SID id specified in the file as
	the default, use the one furthest down the trunk from 1.1.  Don't
	return one on a branch.

Sat May  3 17:17:38 1997  James Youngman  <jay@gnu.org>

	* sf-get.cc:
	Support SCCS files whose first referred-to delta is not numbered 1.
	SunOS can produce these.

	* sf-write.cc, sf-prs.cc, sf-admin.cc, sccsfile.h, sccsfile.cc:
	Added support for the 'e' (encoded) flag.

Sat May  3 11:51:53 1997  James Youngman  <jay@gnu.org>

	* sf-get2.cc:
	In sccs_file::find_requested_sid(), if the requested sid is 0.0.0.0
	(i.e. is_null()), accept the first sid we find as the first guess at
	the best match (but continue to look). [oops, bad idea, see above!]

	* sid.h:
	Fixed bug in the conditionals for sid::valid() and release::valid().

	* Makefile.in: Added dependencies.

Tue Apr 29 01:42:14 1997  James Youngman  <jay@gnu.org>

	*: Decided to consider supporting setuid execution via BSD's
 	sccs(1) command.

Sun Apr 20 22:38:13 1997  James Youngman  <jay@gnu.org>

	* file.cxx: What about support for set-Group-ID execution?
