checking out various versions autumatically

[Michael Bieber]

Hi group,

I'm looking for a way in checking out an arbitrary software projects cvs 
version tree (or a part of it) controlled by a script. In the 'complete 
case' the script should be able to detect all existing versions (nodes) 
for the project in question. The result should be arranged in a 
directory tree. Possible platforms running the script include Linux and 
also Windows systems (one of them is sufficient).
Anybody out there able to guide me in finding a starting point ?
Additional question (might be slightly OT here): Is someone aware of a 
similar solution for subversion ?
