NAME
     cvsgdiff - Graphical Diff for CVS

SYNOPSIS
     cvsgdiff [ <files> ...]
              [ -r <rev1> ]
              [ -r <rev2> ]
              [ -gdiff <gdiff_path> ]
              [ -cvs <cvs_path> ]

DESCRIPTION
     cvsgdiff uses tkdiff or mgdiff to graphically display diffs
     between CVS revisions of a file in your sandbox.  It is
     basically a graphical version of "cvs diff".  If given no
     arguments, cvsgdiff will launch the graphical diff program once
     for every modified file in the current directory.

     If given one or more filenames as arguments, cvsgdiff diplays
     the diffs of each file.  If given a revision, cvsgdiff will
     display the diffs between the file in your sandbox and the BASE
     revision in CVS.  If given two revisions, cvsgdiff will display
     the diffs between the two revisions in CVS for the given file.
     The files in your sandbox are not touched.

     cvsgdiff works by checking out the specified (or defaults to
     BASE) revision of the specified file(s) into your tmp directory
     and then launches a graphics diff program to display the
     differences.  The files in your tmp directory are then removed
     when you exit the graphical diff program.  cvsgdiff currently
     supports tkdiff and mgdiff.  It first checks the environment
     variable GDIFF.  If it is set, that program will be tried first.
     If the GDIFF environment variable specifies an absolute path but
     does not exist, cvsgdiff will then look for tkdiff and mgdiff.

EXAMPLES
     Display diffs for every modified file in and under the current
     directory

         cvsgdiff

     Display diffs for test.pl and test2.pl

         cvsgdiff test.pl test2.pl

     Display diffs between test.pl and CVS revision 0.2 of test.pl

         cvsgdiff -r 0.2 test.pl

     Display diffs between test.pl and the version of test.pl that
     was tagged with RELEASE_TAG

         cvsgdiff -r RELEASE_TAG test.pl

     Display diffs between CVS revisions 0.2 and 0.3 of test.pl

         cvsgdiff -r 0.2 -r 0.3 test.pl
