checkcvswrappers
This is a utility to help manage your cvs wrappers ($CVSROOT/cvswrapers and ~/.cvswrappers). It helps you avoid the situation where you import or add files into a cvs repository with the wrong wrapper, which could mean that when these files are checkout’d they are corrupt. You can read the man page; download a tarball; or browse the cvs repository.
Note that you will also need: cmake (download from here) and the argv library (argv-2.4.0.tar.gz).
