2004-08-01 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.26.
	* Modified driver.h to clearly state the GPL license.
	  This doesn't change anything, but it makes the
	  Savannah people happy.

2004-07-31 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.25. Changes are:
	* Per request from Savannah, added the more detailed licensing
	  text to every source file.
	* Modified the assembly language counting code, based on useful
	  feedback and a test case from Purnendu Ghosh, so that
	  the heuristics work better at guessing the right comment character
	  and they perform well.
	  In particular, the comment character '*' is far better supported.
	* Added support for Delphi project files (.dpr files, which are
	  essentially in Pascal syntax), thanks to Christian Iversen.
	* Some versions of Perl are apparantly causing trouble, but
	  I have not yet found the solution for them (other than using
	  a different version of Perl).  The troublesome line of code
	  in break_filelist, which currently says:
	      open(FH, "-|", "md5sum", $filename) or return undef;
	  This could be changed to:
              open(FH, "-|", "md5sum $filename") or return undef;
	  But I dare not fix it that way, because that would create
	  a security problem.  Imagine downloading someone
	  else's source code (who you don't know), using sloccount, and
	  that other person has created in their source tree a file
	  named like this: "; rm -fr /*" or its variations.
	  I'd rather have the program fail in specific circumstances
	  (users will know when it won't work!) than to insert a known
	  dangerous security vulnerability.  I can't reproduce this problem;
	  it's my hope that those who CAN will help me find a good
	  solution.  For the moment, I'm documenting the problem here and
	  in the TODO list, so that people will realize WHY it hasn't
	  just been "fixed" with the "obvious solution".
	  The answer: I care about security.

2004-05-10 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.24 - a few minor bugfixes and improvements.
	  Automatically tries to use several different MD5 programs, until
	  it finds one that works - this is more flexible, and as a result,
	  it now works out-of-the-box on Apple Mac OS X.
	  SLOCCount now accepts "." as the directory to analyze,
	  it correctly identifies wrapper scripts left by libtool as
	  automatically generated code, and correctly identifies debian/rules
	  files as makefiles. Also, installation documentation has improved.
	  My thanks to Jesus M. Gonzalez-Barahona for telling me about the
	  Debian bug reports and testing of candidate versions.
	  My thanks to Koryn Grant, who told me what needed to be done
	  to get SLOCCount running on Mac OS X (and for testing my change).
	  This version resolves Debian Bug reports #173699,
	  #159609, and #200348.

2004-04-27 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Automatically try several different MD5 programs, looking for
	  a working one.  Originally this program REQUIRED md5sum.
	  This new version tried md5sum, then md5, then openssl.
	  The good news - the program should now 'just work' on
	  Apple Mac OS X.  The bad news - if md5sum doesn't exist,
	  sloccount still has a good chance of working, but will display
	  odd error messages while it searches for a working MD5 program.
	  There doesn't seem to be an easy way in perl to suppress such
	  messages while still permitting "trouble reading data file"
	  messages.  However, doing the test at run-time is much more
	  robust, and this way it at least has a chance of working on
	  systems it didn't work on at all before.
	* Removed the "debian" subdirectory.  There was no need for it;
	  it's best for the Debian package maintainers to control that
	  information on their own.

2004-04-25 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Allow "." and ".." as specifications for directories even
	  when they have no subdirectories.
	  This resolves Debian bug report log #200348
	  ("Sloccount . fails").
	* Correctly identify wrapper scripts left by libtool as
	  automatically generated code.
	  When linking against a libtool library, libtool leaves a wrapper
	  script in the source tree (so that the binary can be executed
	  in-place, without installing it), which includes this:
	  (line) # foo - temporary wrapper script for .libs/foo
	  (line) # Generated by ltmain.sh - GNU libtool 1.4.3 
	                                  (1.922.2.111 2002/10/23 02:54:36)
	  I fixed this by saying that any comment beginning with
	  "Generated by" in the first few lines must be auto-generated
	  code.  This should correctly catch other auto-generated code too.
	  There is a risk that code NOT automatically generated will be
	  incorrectly labelled, but that's unlikely. 
	  This resolves Debian Bug report logs #173699,
	  "sloccount should ignore libtool-generated wrapper scripts".
	* Now identifies "debian/rules" files as a makefile.
	  This resolves Debian Bug report logs - #159609,
	  "sloccount Does not consider debian/rules to be a makefile".
	* Minor fix to sloccount makefile, so that man page installs
	  correctly in some situations that didn't before.
	  My thanks to Jesus M. Gonzalez-Barahona.

2003-11-01 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Version 2.23 - a few minor bugfixes and improvements.

2003-11-01 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Fixed incorrect UTF-8 warnings.  Perl 5.8.0 creates warnings
	  when the LANG value includes ".UTF-8" but the text files read
	  aren't UTF-8.  This causes problems on Red Hat Linux 9 and others,
	  which set LANG to include ".UTF-8" by default.
	  This version quietly removes ".UTF-8" from the LANG value for
	  purposes of sloccount, to eliminate the problem.

2003-11-01 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Fixed bad link to "options" in sloccount.html; my thanks to
	  Barak Zalstein (<Barak.Zalstein, at, ParthusCeva.com) for
	  telling me.
	* Added "--version" option that prints the version number.
	  Thanks to Auke Jilderda (auke.jilderda, at, philips.com)
	  for suggesting this.

2003-11-01 Sam Tregar <sam, at, tregar.com>
	* Fixed a bug in perl_count that prevents it from
	  properly skipping POD.

2003-10-30 Julian Squires <julian, at, greyfirst.ca>
	* Added simple literate Haskell support.
	* Added test cases for literate Haskell support.
	* Updated Common LISP and Modula 3 extensions.

2003-03-08 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Version 2.22 - improved OCAML support, thanks to Michal Moskal.
	  Other minor improvements.

2003-02-15  Jay A. St. Pierre
	* Fixed uninstalling documents to always remove DOC_DIR.

2003-02-15 Michal Moskal
	* Significantly improved OCAML support - complete rewrite of
	  ML handling.

2003-01-28 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Version 2.21 - improved Fortran support (inc. Fortran 90);
	  my thanks to Erik Schnetter for implementing this!

2002-12-17  Erik Schnetter  <schnetter, at, uni-tuebingen.de>
	* Added support for Fortran 90.  Extensions are ".f90" and ".F90".
	* Changed handling of Fortran 77 to include HPF and Open MP
	  statements, and to accept uppercase ".F77" as extension.

2002-12-04 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Version 2.20 - minor portability and documentation improvements.
	* Documentation improvements - more discussion on Intermediate COCOMO.

2002-12-04 Linh Luong <Linh.Luong, at, trw.com>
	* Modified SLOCCount so that it would run on Solaris 2.7 
	  (once Perl is installed and the PATH is set correctly to include
	  the directory where SLOCCount is installed).
	  This required modifying file sloccount to eliminate the
	  test ("[") option "-e", replacing it with the "-r" option
	  ("test -e" is apparantly not supported by Solaris 2.7).
	  Since "-r" should be available on any implementation of "test",
	  this is a nice portable change.

2002-11-16 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Version 2.19, documentation improvement.
	* Documented the "Improved COCOMO" model from Boehm,
	  so that users who want more accurate estimates can do at
	  least a little bit straight from the documentation.
	  For more, as always, see Boehm's book.
	  If anyone wants to implement logical SLOC counting, please be
	  my guest!  Then, COCOMO II could be implemented too.
	* Modified this ChangeLog to document more fully the SGI MIPS problem.

2002-11-16 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Version 2.18, minor bugfix release.
	* Updated the "wc -l" check; it would cause problems for users
	  who had never used sloccount before (because datadir had not
	  been created yet).  Also, the "wc -l" check itself would not
	  reliably identify SGI systems that had horribly buggy "wc"
	  programs; it's believed this is a better check.
	  Thanks to Randal P. Andress for helping with this.
	* Fixed this ChangeLog.  It was Randal P. Andress who identified
	  the "wc -l" bug, not Bob Brown.  Sorry for the misattribution,
	  and thanks for the bugfixing help!
	* Changed rpm building command to work with rpm version 4
	  (as shipped with Red Hat Linux 8.0).  As of Red Hat Linux 8,
	  the "rpm" command only loads files, while there is now a
	  separate "rpmbuild" command for creating rpm files.
	  Those rebuilding with Red Hat Linux 7.X or less (rpm < version 4)
	  will need to edit the makefile slightly, as documented
	  in the makefile, to modify the variable RPMBUILD.
	* "make rpm" now automatically uninstalls sloccount first if it can,
	  to eliminate unnecessary errors when building new versions of
	  sloccount RPMs.  This only affects people modifying and
	  redistributing the code of sloccount (mainly, me).

2002-11-16 Randal P. Andress
	* Fixed get_sloc so that it
	  also accepts --filecounts as well as --filecount.

2002-11-05 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.17, which adds support for Java Server Pages
	  (.jsp), eliminates some warnings in newer Perl implementations,
	  and has a few minor fixes/improvments.

2002-11-18 Randal P. Andress
	* Randal provided the following additional information about this
	really nasty problem on SGI MIPS machines.  It causes gcc
	to not work properly, and thus "wc" won't work properly either.
	SLOCCount now detects that there's a problem and will refuse to
	run if things are screwed up this badly.  For those unfortunate
	few who have to deal with this case, here's additional information
	from Randal Andress:

	When gcc is installed on SGI MIPS from source, sgi-mips-sgi-irix6.x,
	an option specification in the 'specs' file is set
	incorrectly for n32. The offending line is:
	  %{!mno-long64:-D__LONG_MAX__=9223372036854775807LL}
	Which (unless option '-mno-long64' is specified), means that
	LONG_MAX is 64 bits.  The trouble is two fold:
	 1. This should not be the default, since for n32,
	    normally, long is only 32 bits. and
	 2. The option did not carry into the
	    compiler past the pre-processor - so it did not work.
	The simplest fix for gcc (it seems that it can be done locally by 
	editing the specs file) is to have the following line to
	replace the offending line in the specs file:
	  %{long64:-D__LONG_MAX__=9223372036854775807LL}
	This makes the default 32 and only sets it to 64 if you specify 
	'-long64' which *does* work all the way through the compiler.

	I had the binary for gcc 3 on the sgi freeware site installed here and
	looked at it's specs file and found no problem (they have the '-long64'
	option). So it seems that when they build gcc for their freeware
	distribution, they fix it.

	The problem comes when someone downloads and builds gcc for themselves 
	on sgi. Then the installation is faulty and any n32 code that they
	build is subject to this flaw if the source makes use of LONG_MAX
	or any of the values derived from it.

	The real problem turned out to be quite general for sgi n32 gcc. The
	'specs' file and mips.h are not consistent resulting in 'LONG_MAX'
	being given an incorrect value.

	The following 'c' program shows inconsistent values for macros for
	mips-irix n32:
	__LONG_MAX__ (LONG_MAX) and
	_MIPS_SZLONG
	This seems to stem from an improper default option in the specs file
	forcing -D__LONG_MAX__=0x7fffffffffffffff
	to be passed to each compile.

	 Here is the test case, compile command, and output:
	
	 # include <limits.h>
	 #define LONG_MAX_32_BITS 2147483647
	 #include <sys/types.h>
	 int main () {
	 #if LONG_MAX <= LONG_MAX_32_BITS
	   printf ("LONG_MAX <= LONG_MAX_32_BITS = 0x%lx\n",LONG_MAX);
	 #else
	   printf ("LONG_MAX  > LONG_MAX_32_BITS = 0x%llx\n",LONG_MAX);
	 #endif
	
	   printf ("_MIPS_SZLONG     = 0x%x\n",_MIPS_SZLONG);
	   printf ("__LONG_MAX__     = 0x%llx (size:%d)\n",__LONG_MAX__,
	 sizeof
	 (__LONG_MAX__));
	
	 #if LONG_MAX <= LONG_MAX_32_BITS
	   printf ("LONG_MAX         = 0x%lx (size:%d)
	 \n",LONG_MAX,sizeof(LONG_MAX));
	 #else
	   printf ("LONG_MAX         = 0x%llx (size:%d)
	 \n",LONG_MAX,sizeof(LONG_MAX));
	 #endif
	
	   printf ("LONG_MAX_32_BITS = 0x%x (size:%d)
	 \n",LONG_MAX_32_BITS,sizeof(LONG_MAX_32_BITS));
	   return 0;
	 }
	 ============ end test case source.
	
	 >gcc -n32 -v -o test_limits -O0 -v -g test_limits.c
	
	 defines include:....-D__LONG_MAX__=9223372036854775807LL....
	
	 =========== test output:
	 >test_limits
	 LONG_MAX  > LONG_MAX_32_BITS = 0x7fffffffffffffff
	 _MIPS_SZLONG     = 0x20
	 __LONG_MAX__     = 0x7fffffffffffffff (size:8)
	 LONG_MAX         = 0x7fffffffffffffff (size:8)
	 LONG_MAX_32_BITS = 0x7fffffff (size:4)
	
	
	 ======== end test case output
	
	 By changing the specs entry:
	    %{!mno-long64:-D__LONG_MAX__=9223372036854775807LL}
	 to
	    %{long64:-D__LONG_MAX__=9223372036854775807LL}
	 as is discussed in one of the internet reports I sent earlier, the
	 output,
	 after recompiling and running is:
	
	 LONG_MAX <= LONG_MAX_32_BITS = 0x7fffffff
	 _MIPS_SZLONG     = 0x20
	 __LONG_MAX__     = 0x7fffffff (size:4)
	 LONG_MAX         = 0x7fffffff (size:4)
	 LONG_MAX_32_BITS = 0x7fffffff (size:4)

	Although I have not studied it well enough to know exactly why, the 
	problem has to do with the size of (long int) and the attempt of the
	'memchr' code to determine whether or not it can use 64 bit words
	rather than 32 bit words in chunking through the string looking
	for the specified character, "\n"(0x0a) in the case of 'wc'.

2002-11-03 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Fixed makefile install/uninstall scripts to properly handle
	  documentation.
	* Added simple check at beginning of sloccount's execution
	  to make sure "wc -l" actually works.
	  Randal P. Andress has found that on certain SGI machines, "wc -l"
	  produces the wrong answers.  He reports,
	  "You may already know this, but just in case you do not, there is an
	  apparent bug in textutils-1.19  function 'wc' (at least as built on
	  SGI-n32) which is caused by an apparent bug in memchr (*s, c, n).
	  The bug is only evident when counting 'lines only' or
	  'lines and characters' (i.e., when NOT counting words).
	  The result is that the filecount is short...
	  I replaced the memchr with very simple code and it corrected the
	  problem. I then installed textutils-2.1 which does not seem have
	  the problem."
	  I thought about adding this information just to the documentation,
	  but no one would notice it.  By adding a check to the code,
	  most people will neither know nor care about the problem, and
	  the few people it DOES affect will know about the problem
	  right away (instead of reporting wrong answers).
	  Yes, a failing "wc -l" is a pretty horrific bug, but rather
	  than ignore the problem, it's better to detect and address it.
	* Modified documentation everywhere so that it consistently
	  documents "--filecount" as the correct option for filecounts,
	  not "--filecounts".  That way, the documentation is consistent.
	* However, in an effort to "do the right thing", the program sloccount
	  will accept "--filecounts" as an alternative way to specify
	  --filecount.

2002-11-02 Bob Brown <rlb, at, bluemartini.com>
	* Contributed code changes to count Java Server Page (.jsp) files.
	  The code does not pull comments out of embedded
	  javascript.  We don't consider that a serious limitation at all,
	  since no one should be sending embedded javascript comments
	  to client browsers anyhow.  They're extremely rare.
	  David A. Wheeler notes that you could
	  argue that if you _DO_ include such comments, they're
	  not really functioning as comments (since they DO have an
	  affect on the result - they're more like print statements in an
	  older language instead of a traditional language's comments).

2002-11-02 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Eliminated more Perl warnings by adding more
	  defined() wrappers to while() loops in Perl code
	  (based on Randal's suggestion).  The problem is that Perl
	  handles the last line of a file oddly if it doesn't end with
	  a newline indicator, and it consists solely of "0".

2002-11-02 Randal P Andress <Randal_P_Andress, at, raytheon.com>
	* Eliminated some Perl warnings by adding
	  defined() wrappers to while() loops in Perl code.

2002-8-24 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.16, fixed limitations of old Pascal counter.

2002-8-24 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Re-implemented Pascal counter (in flex).  This fixes some problems
	  the old counter had - it handles nested comments with different
	  formats, and strings as well.
	* Removed the BUGS information that described the Pascal counter
	  weaknesses.. since now they're gone!
	* Added an additional detector of automatically generated files -
	  it's an auto-generated file if it starts with
	  "A lexical scanner generated by flex", since flex adds this.
	  Generally, this isn't a problem, since we already detect
	  the filename and matching .c files, but it seems worth doing.

2002-8-22 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.15, a bugfix + small feature improvement.
	  My sincere thanks to Jesus M. Gonzalez-Barahona, who provided
	  patches with lots of useful improvements.

2002-8-22 Jesus M. Gonzalez-Barahona
	* Added support for Standard ML (as language "ml").
	* A patch suggested to the Debian BTS; .hh is also a C++ extension.
	* Some ".inc" files are actually Pascal, not PHP;
	  now ".inc" files are examined binned to either Pascal or PHP
	  depending on their content.
	* Improved detection of Pascal files (particularly for Debian 
	  package fpc-1.0.4).
	* php_count was not closing open files before opening a new one,
	  and therefore sloccount could fail to count PHP code given
	  a VERY LONG list of PHP files in one package.
	* break_filelist had problems with files including <CR> and other
	  weird characters at the end of the filename.  Now fixed.

2002-7-24 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.14. Improved Pascal detection, improved
	  Pascal counting, added a reference to CCCC.

2002-7-24 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Modified Pascal counting; the older (*..*) commenting structure
	  is now supported.  Note that the Pascal counter is still imperfect;
	  it doesn't handle the prioritization between these two commenting
	  systems, and can be fooled by strings that include a
	  comment start indicator.  Rewrites welcome, however, for most
	  people the current code is sufficient.  This really needs to be
	  rewritten in flex; languages with strings and multiline comment
	  structures aren't handled correctly with naive Perl code.
	* Documented the weaknesses in the Pascal counter as BUGS.

2002-7-24 Ian West IWest, at, aethersystems, dot com 
	* Improved heuristic for detecting Pascal programs in break_filelist.
	  Sloccount will now categorize files as Pascal if they have
	  the file type ".pas" as well as ".p", though it still checks
	  the contents to make sure it's really pascal.
	  The heuristic was modified so that it's also considered Pascal
	  if it contains "module" and "end.",
	  or "program", "begin", and "end." in addition to the existing cases.

	  (Ian West used sloccount to analyze a system containing
	   about 1.2 million lines of code in almost 10,000 files;
	   ninety percent of it is Ada, and the bulk of the remainder
	   is split between Pascal and SQL. The following is Ian's
	   more detailed explanation for the change):

	VAX Pascal uses "module" instead of "program" for files that
	have no program block and therefore no "begin".
	There is also no requirement for a Pascal file to have
	procedures or functions, which is the case for files that are
	equivalents of C headers. So I modified the function to
	allow files to be accepted that only contain either:
	"module" and "end."; or "program", "begin", and "end.".
	I considered adding checks for "const", "type", and "var" but
	decided they were not necessary. I have added the extra cases
	without changing the existing logic so as not to upset
	any cases for "unit".  It is possible to optimize the logic
	somewhat, but I felt clarity was better than efficiency.

	I found that some of my Pascal files were getting through
	only because the word "unit" appeared in certain comments.
	So I moved the line for filtering out comments above the lines
	that look for the keywords.

	Pascal in general allows comments in the form (*...*) as well
	as {...}, so I added a line to remove these.

	After making these changes, all my files were correctly
	categorized. I also verified that the sample Pascal files
	from p2c still had the same counts.

	Thank you for developing SLOCCount. It is a very useful tool.

2002-7-15 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Added a reference to CCCC; http://cccc.sourceforge.net/

2002-5-31 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.13.
	* Code cleanups.  Turned on gcc warnings ("-Wall" option) and
	  cleaned up all code that set off a warning.
	  This should make the code more portable as well as cleaner.
	  Made a minor speed optimization on an error branch.

2002-3-30 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.12.
	* Added a "testcode" directory with some sample source code
	  files for testing.  It's small now, but growth is expected.
	  Contributions for this test directory (especially for
	  edge/oddball cases) are welcome.

2002-3-25 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Changed first-line recognizers so that the first line (#!) will
	  matched ignoring case.  For most Unix/Linux systems uppercase
	  script statements won't work, but Windows users.
	* Now recognize SpeedyCGI, a persistent CGI interface for Perl.
	  SpeedyCGI has most of the speed advantages of FastCGI, but
	  has the security advantages of CGI and has the CGI interface
	  (from the application writer's point of view).
	  SpeedyCGI perl scripts have #!/usr/bin/speedy lines instead of
	  #!/usr/bin/perl. More information about SpeedyCGI
	  can be found at http://daemoninc.com/speedycgi/     
	  Thanks to Priyadi Iman Nurcahyo for noticing this.

2002-3-15 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Added filter to remove calls to sudo, so
	  "#!/usr/bin/sudo /usr/bin/python" etc as the first line
	  are correctly identified.

2002-3-7 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Added cross-references to LOCC and CodeCount.  They don't
	  do what I want.. which is why I wrote my own! .. but others
	  may find them useful.

2002-2-28 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.11.
	* Added support for C#.  Any ".cs" file is presumed
	  to be a C# file.  The C SLOC counter is used to count SLOC.
	  Note that C# doesn't have a "header" type (Java doesn't either),
	  so disambiguating headers isn't needed.
	* Added support for regular Haskell source files (.hs).
	  Their syntax is sufficiently similar that just the regular
	  C SLOC counter works.
	  Note that literate Haskell files (.lhs) are _not_ supported,
	  so be sure to process .lhs files into .hs files before counting.
	  There are two different .lhs conventions; for more info, see:
	  http://www.haskell.org/onlinereport/literate.html
	* Tweaked COBOL counter slightly.  Added support in fixed (default)
	  format for "*" and "/" as comment markers in column 1.
	* Modified list of file extensions known not to be source code,
	  based on suffixes(7).  This speeds things very slightly, but the
	  main goal is to make the "unknown" list smaller.
	  That way, it's much easier to see if many source code files
	  were incorectly ignored.  In particular, compressed formats
	  (e.g., ".tgz") and multimedia formats (".wav") were added.
	* Modified documentation to make things clear: If you want source
	  in a compressed file to be counted (e.g. .zip, .tar, .tgz),
	  you need to uncompress the file first!!
	* Modified documentation to clarify that literate programming
	  files must be expanded first.
	* Now recognize ".ph" as Perl (it's "Perl header" code).
	  Please let me know if this creates many false positives
	  (i.e., if there are programs using ".ph" in other ways).
	* File count_unknown_ext modified slightly so that it now examines
	  ~/.slocdata.  Modified documentation so that its use is
	  recommended and explained.  It's been there for a while, but
	  with poor documentation I bet few understand its value.
	* Modified output to clearly say that it's Open Source Software /
	  Free Software, licensed under the GPL.  It was already stated
	  that way in the documentation and code, but clearly stating this
	  on every run makes it even harder to miss.

2002-2-27 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.10.
	* COBOL support added! Now ".cbl" and ".cob" are recognized
	  as COBOL extensions, as well as their uppercase ".CBL" and ".COB".
	  The COBOL counter works as follows:
	  it detects if a "freeform" command has been given.  Unless a
	  freeform command's given, a comment has "*" or "/" in column 7,
	  and a SLOC is a non-comment line with
	  at least one non-whitespace in column 8 or later (including
          columns 72 or greater; it's arguable if a line that's empty
          before column 72 is really a line or a comment, but I've decided
          to count such odd things as lines).
	  If we've gone free-format, a comment is a line that has optional
	  whitespace and then "*".. otherwise, a line with nonwhitespace
	  is a SLOC.
	  Is this good enough?  I think so, but I'm not a major COBOL user.
	  Feedback from real COBOL users would be welcome.
	  A source for COBOL test programs is:
	    http://www.csis.ul.ie/cobol/examples/default.htm
	  Information on COBOL syntax gathered from various locations, inc.:
	    http://cs.hofstra.edu/~vmaffea1/cobol.html
	    http://support.merant.com/websupport/docs/microfocus/books/
	                               nx31books/lrintr.htm
	* Modified handling of uppercase filename extensions so they'll
	  be recognized as well as the more typicaly lowercase extensions.
	  If a file has one or more uppercase letters - and NO
	  lowercase letters - it's assumed that it may be a refugee from
	  an old OS that supported only uppercase filenames.
	  In that circumstance, if the filename extension doesn't match the
	  set of known extensions, it's made into lowercase and recompared
	  against the set of extensions for source code files.
	  This heuristic should improve recognition of source
	  file types for "old" programs using upper-case-only characters.
	  I do have concern that this may be "too greedy" an algorithm, i.e.,
	  it might claim that some files that aren't really source code
	  are now source code.  I don't think it will be a problem, though;
	  many people create filename
	  extensions that only differ by case in most circumstances; the
	  ".c" vs. ".C" thing is an exception, and since Windows folds
	  case it's not a very portable practice.  This is a pretty
	  conservative heuristic; I found Cobol programs with lowercase
	  filenames and uppercase extensions ("x.CBL"), which wouldn't
	  be matched by this heuristic.  For Cobol and Fortran I put in
	  special ".F", ".CBL", and ".COB" patterns to catch them.
	  With those two actions, the program should manage to
	  correctly identify more source files without incorrectly
	  matching non-source files.
	* ".f77" is now also accepted as a Fortran77 extension.
	  Thanks to http://www.webopedia.com/quick_ref/fileextensionsfull.html
	  which has lots of extension information.
	* Fixed a bug in handling top-level directories where there were NO
	  source files at all; in certain cases this would create
	  spurious error messages.  (Fix in compute_all).

2002-1-7 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.09.

2002-1-9 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Added support for the Ruby programming language, thanks to
	  patches from Josef Spillner.
	* Documentation change: added more discussion about COCOMO,
	  in particular why its cost estimates appeared so large.
	  Some programmers think of just the coding part, and only what
	  they'd get paid directly.. but that's less than 10% of the
	  costs.

2002-1-7 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Minor documentation fix - the example for --effort in
	  sloccount.html wasn't quite right (the base documentation
	  for --effort was right, it was just the example that was wrong).
	  My thanks to Kevin the Blue for pointing this out.

2002-1-3 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.08.

2002-1-3 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Based on suggestions by Greg Sjaardema <gdsjaar@sandia.gov>:
	* Modified c_count.c, function count_file to close the stream
	  after the file is analyzed.  Otherwise, this can cause problems
	  with too many open files on some systems, particularly on
	  operating systems with small limits (e.g., Solaris).
	* Added '.F' as a Fortran extension.

2002-1-2 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 2.07.

2002-1-2 Vaclav Slavik <vaclav.slavik@matfyz.cz>
	* Modified the RPM .spec file in the following ways: 
	* By default the RPM package now installs into /usr (so binaries
	  go into /usr/bin).  Note that those who use the makefile directly
	  ("make install"), including tarball users,
	  will still default to /usr/local instead.
	  You can still make the RPM install to /usr/local by using
	  the prefix option, e.g.:
	      rpm -Uvh --prefix=/usr/local sloccount*.rpm
	* Made it use %{_prefix} variable, i.e. changing it to install 
	  in /usr/local or /usr is a matter of changing one line
	* Use wildcards in %files section, so that you don't have to modify 
	  the specfile when you add new executable
	* Mods to make it possible to build the RPM as non-root (i.e. 
	  BuildRoot support, %defattr in %files, PREFIX passed to make install)

2002-1-2 Jesus M. Gonzalez Barahona <jgb@debian.org>
	* Added support for Modula-3 (.m3, .i3).
	* ".sc" files are counted as Lisp.
	* Modified sloccount to handle EVEN LARGER systems (i.e.,
	  so sloccount will scale even more).
	  In a few cases, parameters were passed on the command line
	  and large systems could be so large that the command line was
	  too long.  E.G., Debian GNU/Linux.  This caused a large number
	  of changes to different files to remove these scaleability
	  limitations.
	* All *_count programs now accept "-f filename" and "-f -" options,
	  where 'filename' is a file with a list of filenames to count.
	  Internally the "-f" option with a filename is always used, so
	  that an arbitrarily long list of files can be measured and so
	  that "ps" will show more status information.
	* compute_sloc_lang modified accordingly.
	* get_sloc now has a "--stdin" option.
	* Some small fixes here and there.
	* This closes Debian bug #126503.

2001-12-28 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released sloccount 2.06.

2001-12-27 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Fixed a minor bug in break_filelist, which caused
	  (in extremely unusual circumstances) a problem when
	  disambiguating C from C++ files in complicated situations
	  where this difference was hard to tell.  The symptom: When
	  analyzing some packages (for instance, afterstep-1.6.10 as
	  packaged in Debian 2.2) you would get the following error:
	    Use of uninitialized value in pattern match (m//) at
	    /usr/bin/break_filelist line 962.
	  This could only happen after many other disambiguating rules
	  failed to determine if a file was C or C++ code, so the problem
	  was quite rare.
	  My thanks to Jesus M. Gonzalez-Barahona (in
	  Mostoles, Spain) for the patch that fixes this problem.
	* Modified man page, explaining the problems of filenames with
	  newlines, and also noting the problems with directories
	  beginning with "-" (they might be confused as options).
	* Minor improvements to Changelog text, so that the
	  changes over time were documented more clearly.
	* Note that CEPIS "Upgrade" includes a paper that depends
	  on sloccount.  This is "Counting Potatoes: the Size of Debian 2.2"
	  which counts the size of Debian 2.2 (instead of Red Hat Linux,
	  which is what I counted). The original release is at:
	  <http://www.upgrade-cepis.org/issues/2001/6/upgrade-vII-6.html>.
	  I understand that they'll make some tweaks and
	  release a revision of the paper on the Debian website.
	  It's interesting; Debian 2.2 (released in 2000, and
	  which did NOT have KDE), has 56 million physical SLOC and
	  would have cost $1.8 billion USD to develop traditionally.
	  That's more than Red Hat; see <http://www.dwheeler.com/sloc>.
	  Top languages: C (71.12%), C++ (9.79%), LISP, Shell, Perl,
	  Fotran, Tcl, Objective-C, Assembler, Ada, and Python in that
	  order.  My thanks to the authors!

2001-10-25 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released sloccount 2.05.
	* Added support for detecting and counting PHP code.
	  This was slightly tricky, because PHP's syntax has a few "gotchas"
	  like "here document" strings, closing working even in C++ or sh
	  style comments, and so on.
	  Note - HTML files (.html, .htm, etc) are not examined for PHP code.
          You really shouldn't put a lot of PHP code in HTML documents, because
	  it's a maintenance problem later anyway.
	  The tool assigns every file a single type.. which is a problem,
	  because HTML files could have multiple simultaneous embedded types
	  (PHP, javascript, and HTML text).  If the tool was modified to
	  assign multiple languages to a single file, I'm not sure how
	  to handle the file counts (counts of files for each language).
	  For the moment, I just assign HTML to "html".
	* Modified output so that it adds a header before the language list.

2001-10-23 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released sloccount 2.01 - a minor modification to support
	  Cygwin users.
	* Modified compute_all to make it more portable (== became =);
	  in particular this should help users using Cygwin.
	* Modified documentation to note that, if you install Cygwin,
	  you HAVE to use Unix newlines (not DOS newlines) for the Cygwin
	  install.  Thanks to Mark Ericson for the bug report & for helping
	  me track that down.
	* Minor cleanups to the ChangeLog.

2001-08-26 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released sloccount 2.0 - it's getting a new version number because
	  its internal data format changed. You'll have to re-analyze
	  your system for the new sloccount to work.
	* Improved the heuristics to identify files (esp. .h files)
	  as C, C++, or objective-C.  The code now recognizes
	  ".H" (as well as ".h") as header files.
	  The code realizes that ".cpp" files that begin with .\"
	  or ,\" aren't really C++ files - XFree86 stores many
	  man pages with these extensions (ugh).
	* Added the ability to "--append" analyses.
	  This means that you can analyze some projects, and then
	  repeatedly add new projects.  sloccount even stores and
	  recovers md5 checksums, so it even detects duplicates
	  across the projects (the "first" project gets the duplicate).
	* Added the ability to mark a data directory so that it's not
	  erased (just create a file named "sloc_noerase" in the
	  data directory).  From then on, sloccount won't erase it until
	  you remove the file.
	* Many changes made aren't user-visible.
	  Completely re-organized break_filelist, which was getting
	  incredibly baroque.  I've improved the sloccount code
	  so that adding new languages is much simpler; before, it
	  required a number of changes in different places, which was bad.
	* SLOCCount now creates far fewer files, which is important for
	  analyzing big systems (I was starting to run out of inodes when
	  analyzing entire GNU/Linux distributions).
	  Previous versions created stub files in every child directory
	  for every possible language, even those that weren't used;
	  since most projects only use a few languages, this was costly in
	  terms of inodes.  Also, the totals for each language for a given
	  child directory are now in a single file (all-physical.sloc)
	  instead of being in separate files; this not only reduces inode
	  counts, but it also greatly simplifies later processing & eliminated
	  a bug (now, to process all physical SLOC counts in a given child
	  directory, just process that one file).

2001-06-22 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Per Prabhu Ramachandran's suggestion, recognize ".H" files as
	  ".h"/".hpp" files (note the upper case).

2001-06-20 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 1.9.  This eliminates installation errors
	  with "sql_count" and "makefile_count",
	  detects PostgreSQL embedded C (in addition to Oracle and Informix),
	  improves detection of Pascal code, and includes support for
	  analyzing licenses (if a directory has the file PROGRAM_LICENSE,
	  the file's contents are assumed to have the license name for that
	  top-level program).  It eliminates a portability problem, so
	  hopefully it'll be easier to run it on Unix-like systems.
	  It _still_ requires the "md5sum" program to run.

2001-06-14 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Changed the logic in make_filelists.
	  This version doesn't require a "-L" option to test which GNU
	  programs supported but which others (e.g., Solaris) didn't.
	  It still doesn't normally follow symlinks.
	  Not following subordinate symlinks is important for
	  handling oddities such as pine's build directory
	  /usr/src/redhat/BUILD/pine4.33/ldap in Red Hat 7.1, which
	  includes symlinks to directories not actually inside the
	  package at all (/usr/include and /usr/lib).
	* Added display of licenses in the summary form, if license
	  information is available.
	* Added undocumented programs rpm_unpacker and extract_license.
	  These are not installed at this time, they're just provided as
	  a useful starting point if someone wants them.

2001-06-12 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Added support for license counting.  If the top directory
	  of a program has a file named "PROGRAM_LICENSE", it's copied to
	  the .slocdata entry, and it's reported as part of a licensing total.
	  Note that the file LICENSE is ignored, that's often more complex.

2001-06-08 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Fixed RPM spec file - it accidentally didn't install
	  makefile_count and sql_count.  This would produce spurious
	  errors and inhibited the option of counting makefiles and SQL.
	  Also fixed the makefile to include sql_count in the executable list.

2001-05-16 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Added support for auto-detecting ".pgc" files, which are
	  embedded PostgreSQL - they are assumed to be C files (they COULD
	  be C++ instead; while this will affect categorization it
	  won't affect final SLOC counts).  Also, if there's a ".c" with
	  a corresponding ".pgc" file, the ".c" file is assumed to be
	  auto-generated.
	* Thus, SLOCCount now supports embedded database commands for
	  Oracle, Informix, and PostgreSQL.  MySQL doesn't use an
	  "embedded" approach, but uses a library approach that SLOCCount
	  could already handle.
	* Fixed documentation: HTML reserved characters misused,
	  sql_count undocumented.


2001-05-14 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Added modifications from Gordon Hart to improve detection
	  of Pascal source code files.
	  Pascal files which only have a "unit" in them (not a full program),
	  or have "interface" or "implementation",
	  are now detected as Pascal programs.
	  The original Pascal specification didn't support units, but
	  there are Pascal programs which use them.  This should result in
	  more accurate counts of Pascal software that uses units.
	  He also reminded me that Pascal is case-insensitive, spurring a
	  modification in the detection routines (for those who insist on
	  uppercase keywords.. a truly UGLY format, but we need to
	  support it to correctly identify such source code as Pascal).
	* Modified the documentation to note that I prefer unified diffs.
	  I also added a reference to the TODO file, and from here on
	  I'll post the TODO file separately on my web site.

2001-05-02 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 1.8.  Added several features to support
	  measuring programs with embedded database commands.
	  This includes suporting many Oracle & Informix embedded file types
	  (.pc, .pcc, .pad, .ec, .ecp).  It also optionally counts
	  SQL files (.sql) and makefiles (makefile, Makefile, etc.),
	  though by default they are NOT included in lines-of-code counts.
	  See the (new) TODO file for limitations on makefile identification.

2001-04-30 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Per suggestion from Gary Myer, added optional "--addlang" option
	  to add languages not NORMALLY counted.  Currently it only
	  supports "makefile" and "sql".  The scheme for detecting
	  automatically generated makefiles could use improvement.
	  Normally, makefiles and sql won't be counted in the final reports,
	  but the front-end will make the calculations and if requested their
	  values will be provided.
	* Added an "SQL" counter and a "makefile" counter.
	* Per suggestions from Gary Myer, added detection for files where
	  database commands (Oracle and Informix) are embedded in the code:
	   .pc -> Oracle Preprocessed C code
	   .pcc -> Oracle preprocessed C++ Code
	   .pad -> Oracle preprocessed Ada Code
	   .ec -> Informix preprocessed C code
	   .ecp -> Informix preprocessed C code which calls the C preprocessor 
	           before calling the Informix preprocessor.
	  Handling ".pc" has heuristics, since many use ".pc" to mean
	  "stuff about PCs". Certain filenames not counted as C files (e.g.,
	  "makefile.pc" and "README.pc") if they end in ".pc".
	  Note that if you stick C++ code into .pc files, it's counted as C.

	  These embedded files are normal source files of the respective
	  language, with database commands stuck into them, e.g.,
	    EXEC SQL select FIELD into :variable from TABLE;
	  which performs a select statement and puts the result into the 
	  variable.  The database preprocessor simply reads this file,
	  and converts all "EXEC SQL" statements into the appropriate calls
	  and outputs a normal program.

	  Currently the "automatically generated" detectors don't detect
	  this case.  For the moment, just make sure the generated files
	  aren't around while running SLOCCount.

	  Currently the following are not handled (future release?):
	   .pco -> Oracle preprocessed Cobol Code
	   .pfo -> Oracle preprocessed Fortran Code
	  I don't have a Cobol counter.  The Fortran counter only works
	  for f77, and I doubt .pfo is limited to that.



2001-04-27 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Per suggestions from Gary Myer,
	  added ".a" and ".so" to the "not" list, since these are 
	  libraries not source, and added the filename "Root" to the
	  "not" file list ("Root" has special meaning to CVS).
	* Added a note about needing "md5sum" (Gary Myer)
	* Added a TODO file.  If something's on the TODO list that you'd
	  like, please write the code and send it in.
	* Noted that running on Cygwin is MUCH slower than when running
	  on Linux.  Truth in advertizing is only fair.

2001-04-26 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Release version 1.6: the big change is support for running on
	  Windows.  Windows users must install Cygwin first.
	* Modified makefile so that SLOCCount can run on Windows systems
	  if "Cygwin" is installed.  The basic modifications to do this
	  were developed by John Clezy -- Thanks!!!  I spent time merging
	  his makefile and mine so that a single makefile could be used on
	  both Windows and Unix.
	* Documented how to install and run SLOCCount on Windows using cygwin.
	* Changed default prefix to /usr/local; you can set PREFIX to
	  change this, e.g., "make PREFIX=/usr".
	* When counting a single project, sloccount now also reports
	  "Estimated average number of developers", which is simply
	  the person-months divided by months.  As with all estimates, take
	  it with an ocean of salt.  This isn't reported for multiproject
	  queries; properly doing this would require "packing" to compensate
	  for the fact that small projects complete before large ones if
	  started simultaneously.
	* Improved man page (fixed a typo, etc.).

2001-01-10 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released version 1.4.  This is an "ease of use" release,
	  greatly simplifying the installation and use of SLOCCount.
	  The new front-end tool "sloccount" does all the work in one step -
	  now just type "sloccount DIRECTORY" and it's all counted.
	  An RPM makes installation trivial for RPM-based systems.
	  A man page is now available.  There are now rules for
	  "make install" and "make uninstall" too.
	  Other improvements include a schedule estimator and options
	  to control the effort and schedule estimators.

2001-01-07 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Added an estimator of schedule as well as effort.
	* Added various options to control the effort and
	  cost estimation: "--effort", "--personcost", "--overhead",
	  and "--schedule".
	  Now people can (through options) control the assumptions made
	  in the effort and cost estimations from the command line.
	  The output now shows the effort estimation model used.
	* Changed the output slightly to pretty it up and note that
	  it's development EFFORT not TIME that is shown.
	* Added a note at bottom asking for credit.  I don't ask for any
	  money, but I'd like some credit if you refer to the data the
	  tool generates; a gentle reminder in the output seemed like the
	  easiest way to ask for this credit.
	* Created an RPM package; now RPM-based systems can EASILY
	  install it.  It's a relocatable package, so hopefully
	  "alien" can easily translate it to other formats
	  (such as Debian's .deb format).
	* Created a "man" page for sloccount.

2001-01-06 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Added front-end tool "sloccount", GREATLY improving ease-of-use.
	  The tool "sloccount" invokes all the other SLOCCount tools
	  in the right order, performing a count of a typical project
	  or set of projects.  From now on, this is expected to be the
	  "usual" interface, though the pieces will still be documented
	  to help those with more unusual needs.
	  From now on, "SLOCCount" is the entire package, and
	  "sloccount" is this front-end tool.
	* Added "--datadir" option to make_filelists (to support
	  "sloccount").
	* get_sloc: No longer displays languages with 0 counts.
	* Documentation: documented "sloccount"; this caused major changes,
	  since "sloccount" is now the recommended interface for all but
	  those with complicated requirements.
	* compute_filecount: minor optimization/simplication

2001-01-05 David A. Wheeler <dwheeler, at, dwheeler.com>
	* Released vesion 1.2.
	* Changed the name of many programs, as part of a general clean-up.
	  I changed "compute_all" to "compute_sloc", and eliminated
	  most of the other "compute_*" files (replacing it with
	  "compute_sloc_lang").  I also changed "get_data" to "get_sloc".
	  This is part of a general clean-up, so that
	  if someone wants to package this program for installation they
	  don't have a thousand tiny programs polluting the namespace.
	  Adding "sloc" to the names makes namespace collisions less likely.
	  I also worked to make the program simpler.
	* Made a number of documentation fixes - my thanks to Clyde Roby
	  for giving me feedback.
	* Changed all "*_count" programs to consistently print at the end
	  "Total:" on a line by itself, followed on the next line by
	  the total lines of code all by itself.  This makes the new program
	  get_sloc_detail simpler to implement, and also enables
	  get_sloc_detail to perform some error detection.
	* Changed name of compressed file to ".tar.gz" and modified docs
	  appropriately.  The problem is a bug in Netscape 4.7 clients
	  running on Windows; it appears that ".tgz" files don't get fully
	  downloaded from my hosting webserver because no type information
	  is provided.  Originally, I tried to change the website to fix this
	  by creating ".htaccess" files, but that didn't work with either:
	    AddEncoding x-gzip gz tgz
	    AddType application/x-tar .tgz
	  or:
	       AddEncoding application/octet-stream tgz
	  So, we'll switch to .tar.gz, which works.
	  My thanks to Christopher Lott for this feedback.
	* Removed a few garbage files.
	* Added information to documentation on how to handle HUGE sets
	  of data directory children, i.e., where you can't even use "*"
	  to list the data directory children.  I don't have a directory
	  of that kind of scale, so I can't test it directly,
	  but I can at least discuss how to do it; it SHOULD work.
	* Changed makefile so that "ChangeLog" is now visible on the web.

	* Minor fixes to documentation.
	* Added "--crossdups" option to break_filelist.
	* Documented count_unknown_ext.
	* Created new tool, "get_sloc_detail", and documented it.
	  Now you can get a complete report of all the SLOC data in one big
	  file (e.g., for exporting to another tool for analysis).
