I would also add the common use of the term "distribution" to that
glossary as well.

At http://python.org/download/ , that big software archive that you
download, unpack, and install---giving you a Python installed on your
system---is referred to as a "distribution". Ex., "the python.org
Python distribution", "the ActiveState Python distribution", etc.

Enthought calls theirs a distribution as well:

Incidentally, Perl calls theirs distributions too:
http://www.cpan.org/ (source code distribution available here
http://www.cpan.org/src/README.html ).

Ruby calls theirs distributions as well http://www.ruby-lang.org/en/downloads/ .
