redmenace's builds would qualify as CVS builds
CVS = Concurrent Version System
it's the tool that allows 20 programmers spread all over the world to work on the same program simulatenously without major headaches - it contains the latest version of the code at a central location
a programmer can "checkout" the code, make alterations then submit those alterations - and only those alterations go in, so if another programmer simultanously changed some other part of the same file both changes take place
so a "CVS build" means "A build based upon the most up to date code available"
