Didn't know that; that's great.  "Source available on request" usually
scares me off, but I suppose they just haven't gotten around to
packaging it up properly, or don't want the hassle of leading an open
source project.

I'm afraid the theory flies a ways over my head, but it sure seems
cool that one could use antlr to create processors specialized for a
(human-readable) domain language and be able to use XSugar to get all
the benefits of (barely human-readable) XML e.g. for documentation.
Might not work for all languages, but for data languages in particular
I would think one could do interesting things (my own little project
is a typesetting language).  Then again, there's always Lua.  ;)
