# HTML parser
# Jim Davis, July 15 1994

# This is an HTML parser not an SGML parser.  It does not parse a DTD,
# The DTD is implicit in the code, and specific to HTML.  
# The processing of the HTML can be customized by the user by
#   1) Defining routines to be called for various tags (see Begin and End arrays)
#   2) Defining routines html_content and html_whitespace

# This is not a validating parser.   It does not check the content model
# eg you can use DT outside a DL and it won't know.  It is too liberal in
# what tags are allowed to minimize what other tags.

# Bugs - can't parse the prolog or whatever you call it
#   <!DOCTYPE HTML [
#     <!entity % HTML.Minimal "INCLUDE">
#     <!-- Include standard HTML DTD -->
#     <!ENTITY % html PUBLIC "-//connolly hal.com//DTD WWW HTML 1.8//EN">
#     %html;
#     ]>

# modified 3 Aug to add a bunch of HTML 2.0 tags
# modified 3 Sept to print HTML stack to STDERR not STDOUT, to add new
#  routines html_begin_doc and html_end_doc for application specific cleanup
#  and to break parse_html into two pieces.
# modified 30 Sept 94.  parse_attributes now handles tag attributes that
#   don't have values.  thanks to  Bill Simpson-Young <bill@syd.dit.csiro.au>
#   for the code.
# modified 17 Apr 95 to support FORMS tags.
#
# modified 6 July 1995 by Ti Lian Hwang <tilh@sin-co.sin-ro.dhl.com>
#   to handle 'printer drivers' - files to be 'require' depending on $TERM
#   files are to have name of 'h2a_$TERM.pl'
