cvsps in root of a checkout (not in one specific module)

Question

I've seen this on a couple of different repos.

I want to import all the top level modules of a CVS repo into a single git repo.

So:

cvs co .
cvsps

but this fails, giving lots of messages like this:

WARNING: file X doesn't match strip_path Y. ignoring.

and only outputting 5 trivial seeming patches.

I can run cvsps for each module, and get reasonable patch sets for each of them. But I want this for the whole repo rather than having a separate history for each module.
