distribution: n. 1. A software source tree packaged for
distribution; but see kit. Since about 1996 unqualified use of
this term often implies `Linux distribution'. 2. A vague term
encompassing mailing lists and Usenet newsgroups (but not BBSfora); any topic-oriented message channel with multiple
recipients. 3. An information-space domain (usually loosely
correlated with geography) to which propagation of a Usenet message
is restricted; a much-underutilized feature.
