The X11 sample server, from which this code base derives, was
originally designed by Phil Karlton and Susan Angebrandt of Digital,
and Bob Scheifler (MIT). The original ddx and mi implementation was by
Raymond Drewry and Todd Newman.

Major reimplementation has occurred over the years, by Bob Scheifler
of MIT and the X Consortium, Keith Packard (of MIT, NCD, SuSE, HP) and
many others. fb has replaced the old cfb code, and was written by
Keith Packard.

DDX drivers have been written by many companies and people over
the years, too numerous to name here.  This tree contains the kdrive
driver written by Keith Packard, the Cygwin/X project's driver, and also
the XFree86 DDX. As other ddx frameworks are added, this author's list
will need extensive additions.

The KDrive DDX was derived from the X11 sample server, and was largely written
by Keith Packard. Anders Carlsson and Jaymz Julian made significant
contributions.

The Xizzle (XFree86) DDX was largely written by the XFree86 Project, Inc, with
substantial contributions by others.

The GLX implementation was provided by SGI.

XXX this needs work, particularly for DRI/mesa etc.XXX
XXX full xfree86 ddx credit
XXX am I right about KDrive?

Eric Anholt has been reworking the DRI driver for this X server implementation.
