    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.
