Compare two different snapshots in time of CVS projects : compare_cvs_versions

`compare_cvs_versions`

requires Ruby to be installed.

compare_cvs_versions takes two directory names as arguments, which should contain two different snapshots in time of a project under CVS control.

compare_cvs_versions enables you to compare those two versions of the project and to generate a side-by-side diff of the filenames and version numbers. The comparison is done soley based on the version numbers which are stored in the CVS/Entries files.
e.g.:

        # mkdir /tmp/past ; cd /tmp/past
        # cvs co -D past-date   projectname

        # mkdir /tmp/today ; cd /tmp/today
        # cvs co  projectname

	# compare_cvs_versions /tmp/past  /tmp/today 
	./Makefile                                     1.9   =      1.9
	./README                                       1.2   =      1.2
	./certsrv/VCafe.vep                            1.2  >>>
	./certsrv/config/kra-key.db                    1.2   =      1.2
	./certsrv/config/ns-certsrv4_2SP2.conf              <<<     1.1
	./certsrv/config/ra-cert7.db                   1.2   =      1.2
	./certsrv/run.mk                               1.3   <      1.4

The results of comparing the two versions is indicated by:

>>> file exists only in first directory
<<< file exists only in second directory
< files version number is ascending
> files version number is descending
= files version number did not change

compare_cvs_versions uses the CVS/Entries files within the checked-out directories. Directory names are ommitted in the output (because they don't have version numbers).
