There's the DEFUN tutorial that you can grab as a text file from
http://tmp.barzilay.org/tutorial.txt -- it covers defining a new
language in several ways.  But it doesn't get to defining a new syntax
reader yet.  (It should, in the future, and then it should also become
a proper guide in the documentation.)
