(Usenet, possibly from DEC) Slang fOR a full software distribution, as opposed to a patchOR 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. [Jargon File] (1994-11-18)
