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.
