Hi Steve: The nice thing or at least one of them about using cvs is it only commits modified files which are part of the cvs module. Any object files or backup or anything not part of the module do not get checked in when you do a commit. So your question isn't really a concern. If you are going to submit diff's to us then keep two trees and take a diff -urN between the trees when you are satisfied with your modifications.
