This is a portable version of Modula-3 ( http://en.wikipedia.org/wiki/Modula-3 ), upon which cvsup is designed. Csup is a rewrite of cvsup in the C language, and as such can be included as part of the base operating system. It is only linked against a few system libraries. This also means it can be built using the same tools and system compiler whenever the system itself is updated. Csup is faster, built-in, and has no third party dependencies. Theoretically it should have less potential for problems. Cvsup is a third party port, which itself depends on other third party ports. -Mike
