Hi Albert,

Tim Wichmanns nbcache utilities consist of two Perl scripts. The first one, 
rmnbcache, is a command-line utility supposed to be called by the notebook 
author on his notebook files before checking them in. rmnbcache strips all 
image and cell cache data from a notebook, thereby greatly reducing file 
size. The script is independent of the source-code control system used; it 
can be used with RCS, CVS, SVN, ClearCase, ... Of course, you *could* call 
rmnbcache automatically in a CVS or SVN pre-commit check script, but "server 
side" is not a requirement and was not the original design intention.

On the other hand, the second Perl program, testnbcache, is meant to be used 
as a server-side pre-commit check script and was designed for use with CVS. 
testnbcache checks if a notebook being checked in still has cache data and 
rejects a commit if this is the case. If you want to use it with SVN, then 
you would have to write a SVN pre-commit hook script that calls testnbcache 
as a subprogram.

I am using the nbcache utilities for Mathematica up to v5.2 in both CVS and SVN 
environments. I have no experience with v6 either, but since the tools are 
still being used by my former colleagues for Mathematica application
development (www.analog-insydes.de) up to v6, I suppose that they still
work the way they did for previous Mathematica versions.

Best regards,

Eckhard
