    DESCRIPTION
           The FHist program contains 3 utilities, a file history
           tool ``fhist'', a file comparison tool ``fcomp'', and a
           file merging tool ``fmerge'.  All three are bundled
           together, because they all use the same minimal-difference
           algorithm.

           fhist
    	       Keeps track of versions of a file.  See fhist(1)
    	       for more	information.

           fcomp
    	       Compares	two versions of	a file.	 See fcomp(1) for
    	       more information.

           fmerge
    	       Merges together edits from two descendants of a
    	       file.  See fmerge(1) for	more information.

           The history tool	presented here,	fhist, is a minimal
           history tool.  It provides no locking or	branching.  This
           can be useful in	contexts where the configuration
           management or change control be being provided by some
           other tool.

    RELEASE	NOTES
           For excruciating	detail,	and also acknowledgements of
           those who generously sent me feedback, please see the
           etc/CHANGES.1.6 file included in	this distribution.

           A number	of features and	bug fixes have been added to
           fhist with this release.	 A few of them are detailed here:

       Version 1.6
           * An RPM	spec file has been added to the	distribution.

           * The code is now more robust about what	various	UNIX
           systems return from pathconf().

           * A bug with the	``fcomp	-blank'' option	has been fixed.

       Version 1.5
           * Binary	files are now detected on input, and the
           utilities file gracefully with a	warning	or error message,
           as appropriate.

           * Some buffer over-run bugs have	been fixed.

           * Several improvements have been	made to	the portability.

       Version 1.4
           * The install and build procedures have been made more
           robust, and they	take note of more of the information
           provided	by GNU Autoconf.

           * The error messages have been internationalized, so it is
           now possible to obtain error messages in	your native
           language.  (If you would	like to	contribute with	error
           message translations, please contact the	author.)

           * An LSM	description has	been added, along with a HTML
           page to present it all nicely at	the archive site.

           * A RedHat Package Manager spec file has	been added, so
           that a RedHat package can be created.  The spec file is in
           the standard distribution.

       Version 1.3
           This version was	not distributed	 at all.

       Version 1.2
           This version was	not distributed	very widely.

           * The non-standard isblank function is no longer	used, it
           cause too many portability problems.

           * The use of pathconf is	not more robust	for more
           operating systems.

       Version 1.1
           * The fhist package now uses a shell script called
           configure to configure itself.  This script is generated
           using the GNU Autoconf utility.	This should make fhist
           significantly easier to configure, and significantly more
           portable.

           * A bug has been	fixed in the conflict reporting	of the
           fmerge program.	It now correctly opens the conflicts
           file.

           * The fhist program now uses pathconf(2)	to determine file
           name length limits.
