Extensions come in two flavors, server and client (and most commonly,
combinations of both).  The interfaces for writing server extensions
are defined in the following locations under the X source tree:

R3: doc/Server/ext.doc
R4: mit/doc/Server/ddx.tbl.ms

A good description of the Xlib hooks for adding client-side extensions
can be found in Appendix C of "The X Window System: C Library and Protocol
Reference" ala Scheifler, Gettys, and Newman ("The Red Book").

The following directories contain examples of both server and client
extensions:

R3: extensions
R4: mit/extensions
