kit

n. [Usenet; poss.: fr.: DEC slang for a full software distribution, as
opposed to a patch or upgrade] A source software distribution that has been
packaged in such a way that it can (theoretically) be unpacked and installed
according to a series of steps using only standard Unix tools, and entirely
documented by some reasonable chain of references from the top-level README
file. The more general term distribution may imply that special tools or
more stringent conditions on the host environment are required.
