MacCVSPro 2.7d3 appears to ignore the folder name when
determining if the current folder is a legitimate part of the currently
checked out archive. This caused some problems for me
because I was reorganizing my directory structure I simply
renamed the directories instead of creating new ones and then
copying the contents of the old directory into the new one.
Also, since Interface Builder and Project Builder project files (.nib
and .pbproj) aren't probably recognized as bundles, it is easy to
forget to delete the "invisible" CVS folder inside the bundle when
copying them and so MacCVSPro incorrectly assumes that their
check-in status in the CVS folder is correct. It isn't.
