2. Authorship of XEmacs
XEmacs is the result of the time and effort of many people, and the
active developers have changed over time. There are two major
components of the XEmacs effort – writing the code itself and providing
all the support work (testing the code, releasing beta and final
versions, handling patches, reading bug reports, maintaining the web
site, managing the mailing lists, etc. etc.). Neither component would
work without the other.
CODING
The primary code contributor over the years has been Ben Wing (active
since late 1992). Between 1991 and 1995, large amounts of coding was
contributed by Jamie Zawinski and Chuck Thompson. Many other people
have authored major subsystems or otherwise contributed large amounts of
code, including Andy Piper, Hrvoje Niksic, Jerry James, Jonathan Harris,
Kyle Jones, Martin Buchholz, Michael Sperber, Olivier Galibert, Richard
Mlynarik, Stig, William Perry and plenty of others.

- -
Jamie Zawinski (April 1991 - June 1994, 19.0 - 19.10)
The recent overlapping dates are intentional, since two or three trees
are maintained simultaneously at any point.
Other major support work:
- -
Adrian Aichner wrote and maintains the web site.
- -
Stephen Turnbull has produced many of the beta and semi-stable releases
and has attempted to be the "face" of XEmacs on the newsgroups and
mailing lists.
- -
Steve Youngs, Ville Skyttä¬ and now Norbert Koch have taken turns
maintaining the packages.
- -
Vin Shelton maintains the stable releases.
- -
Testing - #### Norbert, Adrian, ???
