The CVSTools provide a simple project versioning system built upon CVS
which is used by all PADL software.  These tools are also required to
build NetInfo for Linux and our commerial software.  The following scripts
are included in CVSTools:

checkpoint
Based on Apple's checkpoint program, this creates Perl program the
CVSVersionInfo.txt file for a work area (when invoked with -create).  To
checkpoint (i.e. increment the version number and create a CVS tag) type
checkpoint with no arguments, or with the new version number as an
argument.

cvslib.pl
Common library functions used by some of these scripts for getting the
repository and project names.  One can override CVSVersionInfo.txt
location with the CVSVERSIONDIR environment variable, which is useful for
nested source trees where one wishes to pull in the top level version info
for the project name, and the current directory name for the program.

tarup
Executes cvs export and then creates a tarball in
~/dist/project-version.tar.gz.

vers_string
Equivalent of OS X's /usr/bin/vers_string, instead using
CVSVersionInfo.txt the repository and project names.
