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
