TkCVS is a Tcl/Tk-based graphical interface to the CVS and Subversion
configuration management systems. It will also help with RCS. TkDiff
is included for browsing and merging your changes.
TkCVS shows the status of the files in the current working directory,
and has tools for tagging, merging, importing, exporting, checking
in/out, and other user operations.
TkCVS also aids in browsing the repository. For Subversion, the
repository tree is browsed like an ordinary file tree. For CVS, the
CVSROOT/modules file is read. TkCVS extends CVS with a method to
produce a "user friendly" listing of modules. This requires special
comments in the CVSROOT/modules file.
Although TkCVS now supports Subversion, it will still work happily
without it in your CVS directories. It didn't abandon CVS, it just
grew some new capabilities.
