New app server based on XPCOM

XP Server is an app server based on XPCOM and Apache.
Requests are made to the Apache server and handled by
a module. The module reads XML template files and then
uses XPCOM to create a SAX chain of components to
handle the request.  Components can be written in C,
Java, or Javascript. There are existing components for
XML, XSLT, 3D charting, GD graphics, FOP to PDF and
database integration. XP Server was originally written
for a dotcom venture that didn't make it, the code has
been donated to mozdev.org and it's looking for new
owners.
