- *			General SGML Parser code		SGML.c
- *			========================
- *
- *	This module implements an HTStream object.  To parse an
- *	SGML file, create this object which is a parser.  The object
- *	is (currently) created by being passed a DTD structure,
- *	and a target HTStructured object at which to throw the parsed stuff.
- *
- *	 6 Feb 93  Binary searches used. Interface modified.
