#!/usr/bin/perl -w
#
# usage: ldp_print <single_file.html>
#
# Creates a PDF variant of a single-file HTML representation of a
# DocBook SGML (or XML) instance. This simple wrapper assumes that
# the file was created using {open}jade in a manner similar to:
#
#	jade -t sgml -i html -V nochunks -d $style $fname > $fname.html
#
# Give this script the filename as an argument. It will then parse
# the file into 'title.html' and 'body.html' and send each to
# htmldoc (as the corresponding title page and body of the document).
#
#
# CAVEATS:
#
# Assumes perl is in /usr/bin; adjust if necessary
#
# You may need to specify where the htmldoc executable resides.
# The script assumes it's within your $PATH.
#
# If you want Postscript as an output variant, uncomment the 
# appropriate lines (see below).
#
# Relies on output from a DocBook instance created via DSSSL/{open}jade!
#
# Cleans up (removes) the intermediate files it creates (but not the
# PDF or Postscript files, obviously!)
#
# Works silently; PDF (PostScript) will be created in the same directory
# as was specified for the input (single-file HTML) file.
#
# Provided without warranty or support!
