"""Print a list of files that are mentioned in CVS directories.

Usage: cvsfiles.py [-n file] [directory] ...

If the '-n file' option is given, only files under CVS that are newer

than the given file are printed; by default, all files under CVS are

printed.  As a special case, if a file does not exist, it is always

printed.
