-# data -- only char and entity references and end tags are special)
-# and CDATA (character data -- only end tags are special).

-# SGML parser base class -- find tags and call handler functions.
-# Usage: p = SGMLParser(); p.feed(data); ...; p.close().
-# The dtd is defined by deriving a class which defines methods
-# with special names to handle tags: start_foo and end_foo to handle
-# <foo> and </foo>, respectively, or do_foo to handle <foo> by itself.
-# (Tags are converted to lower case for this purpose.)  The data
-# between tags is passed to the parser by calling self.handle_data()
-# with some data as argument (the data may be split up in arbutrary
-# chunks).  Entity references are passed by calling
-# self.handle_entityref() with the entity reference as argument.
