+1999-08-19 1.2 Shenghuo ZHU  <zsh@cs.rochester.edu>
+
+	* version.c: Add configure.
+
+	* file.c: Rename xbitmap to compface_xbitmap.
+
+2000-05-15 1.3 Ken Yap <ken_yap@users.sourceforge.net>
+
+        * uncmain.c, cmain.c: -X didn't work in 1.2, references to xbitmap
+	  replaced by compface_xbitmap or removed, depending.
+
+2000-11-22  Isaac Hollander  <ysh@mindspring.com>
+
+	* version.c (version): incremented version
+
+2000-11-22  Isaac Hollander  <ysh@mindspring.com>
+
+	* cmain.c, uncmain.c, configure.in: added support for strerror()
+	for those systems without sys_errlist[] such as 64 bit Solaris
+
+2004-12-??  Ben Wing  <ben@666.com>
+
+	Version 1.5.0: Added configure support; redid for ANSI C.  Added
+	Windows makefile.  Various other changes.
+
+2005-01-??  Ben Wing  <ben@666.com>
+
+	Version 1.5.1: Added missing `configure', generated from
+	`configure.in'.
+
+2005-08-04  Ben Wing  <ben@666.com>
+
+	Version 1.5.2: Fixed CRLF endings in sources.  Moved configure.in to
+	configure.ac and rewrote obsolete constructions.  Redid installation
+	in `make install' so it actually worked, including on Cygwin
+	(needs the EXEEXT variable from `configure').

+Compface - 48x48x1 image compression and decompression
+Copyright (c) James Ashton 1990.
+Written 89/11/11
+
+Feel free to distribute this source at will so long as the above
+message and this message are included in full.
+
+[I have put MIT in the License field of the LSM descriptions since this
+seems to capture the original author's intent most closely, bearing in
+mind that he wrote this before the various free software licenses were
+categorised. - Ken]
+
+The programme (two programmes really - but they're just links to each
+other) converts 48x48x1 images to and from a compressed format.  The
+uncompressed images are expected to contain 48x48/4 (576) hex digits.
+All other characters and any `0's followed by `X' or `x' are ignored.
+Usually the files are 48 lines of "0x%04X,0x%04X,0x%04X,".  The
+compressed images contain some number of printable characters.  Non
+printable characters, including ` ' are ignored.  The purpose of the
+programme is to allow the inclusion of face images within mail headers
+using the field name `X-face: '.
+
+The programmes make use of a library which can be used to allow the
+compression and decompression algorithms to be used in other
+programmes such as mail despatchers and mail notification daemons.
+
+A small amount of editing in the Makefile may be required to get it
+going - mainly setting EXECUTABLE to what you want and putting the
+manual entry in the right place.

+
+I have merged the -X patch by Piete Brooks <Piete.Brooks@cl.cam.ac.uk>
+into the sources and amended the man page. I have given this the
+version number 1.1 so that it can be submitted to freshmeat.net and
+metalabs.unc.edu.

+Added support for strerror().  Incremented version to 1.4
+
+2004-12-23 Ben Wing <ben@666.com>
+
+Added config.h; added makefile.vc for compiling under Windows;
+added Stig's script xbm2xface.pl for generating xfaces; fixed
+various compile problems.  Incremented version to 1.5.

+.B uncompface
+[-X] [

+.SH DESCRIPTION
+.IX  compface  ""  "\fLcompface\fP \(em compress face image files"
+.IX  uncompface  ""  "\fLuncompface\fP \(em uncompress face image files"
+.I compface
+is a filter for generating highly compressed representations of 48x48x1
+face image files.
+.I uncompface
+is an inverse filter which performs an inverse transformation with no
+loss of data.
+The algorithm used is highly tuned for its purpose and achieves better
+than a five to one compression ratio on average.
+Arguments operate identically for both programmes.
+The first argument, if present, causes input to be taken from the named
+file instead of from standard input unless it is the string ``-''.
+A second argument, if present, causes output to go to the named file
+instead of to standard output unless it is the string ``-''.
+Subsequent pairs of arguments may be used to specify further pairs
+of input and output files.
+.LP
+The input format for
+.I compface
+(and the output format for
+.IR uncompface )
+is 48 lines each of 3 sixteen bit hexadecimal integers, comma terminated in C
+initialiser style.
+The output format of
+.I compface
+(and the input format for
+.IR uncompface )
+is some number of lines made up of a space followed by printable
+characters (in the range ``!'' to ``~'' inclusive).
+The first line contains 72 characters and following lines contain
+79 characters except that the last line may be short.
+.LP
+If the -X option is given to uncompface, it generates XBM format
+directly.
+.LP
+The amount of compression obtained varies between face image files but
+the output of
+.I compface
+averages less than 200 characters.
+The average number of output lines is three.
+.SH DIAGNOSTICS
+Exit status is normally 0.
+Possible errors include IO errors when opening, reading or writing
+files, format errors in
+.I compface
+input files and invalid arguments.
+Each results in an explanatory message on standard error and an exit status
+of 1.
+A warning will be produced if
+.I compface
+detects extra input data.
+.SH BUGS
+Nominating standard input as input more than once does not work.

+.TH COMPFACE 3 "25 January 1990"
+.SH NAME
+compface, uncompface \- compress and expand 48x48x1 face image files
+.SH SYNOPSIS
+.B compface (buf)
+.LP
+.B uncompface (buf)
+.LP
+.B char *buf
+.SH DESCRIPTION
+.IX  compface  ""  "\fLcompface\fP \(em compress face image files"
+.IX  uncompface  ""  "\fLuncompface\fP \(em uncompress face image files"
+.I compface
+is a function for generating highly compressed representations of 48x48x1
+face image files.
+.I uncompface
+is an inverse function which performs an inverse transformation with no
+loss of data.
+The algorithm used is highly tuned for its purpose and achieves better
+than a five to one compression ratio on average.
+In both functions, input is via a NULL terminated string and a NULL terminated
+output string is written over the input string.
+.I Buf
+should therefore point to a block of 2K size or more to avoid buffer
+overruns during output generation.
+.LP
+The input format for
+.I compface
+(and the output format for
+.IR uncompface )
+is 48 lines each of 3 sixteen bit hexadecimal integers, comma terminated in C
+initialiser style.
+The output format of
+.I compface
+(and the input format for
+.IR uncompface )
+is some number of lines made up of a space followed by printable
+characters (in the range ``!'' to ``~'' inclusive).
+The first line contains 72 characters and following lines contain
+79 characters except that the last line may be short.
+.LP
+The amount of compression obtained varies between face image files but
+the output of
+.I compface
+averages less than 200 characters.
+The average number of output lines is three.
+.SH DIAGNOSTICS
+The return value is normally 0.
+1 will be returned if extra input has been ignored during a compress operation.
+-1 is returned in the case of an invalid input format.
+-2 is returned if an internal buffer overrun occurs.
