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.
