CVS interface module

[Jim]

Hello,

Inside of a Python script I need to work a CVS archive.  Nothing fancy,
but I need to update the local tree, change or add some files from time
to time, and commit.  Naturally I looked for a module that would allow
me to easily see if there were conflicts, the server is down, etc.

I've looked in this group, Googled around, etc., but I've not found
anything.  Is there a reasonably mature project that people use for
this purpose?

Thanks,
Jim
