#
# Convert a single gnuplot demo script to a web page
# Usage:
#	webify xxx
#
# Reads xxx.dem and creates xxx.html along with associated 
# png images output to xxx.<n>.png 
#
# If gpsavediff is present also create a set of scripts
# xxx.<n>.gnu corresponding to the minimal set of commands 
# needed to generate that png image.
#
# If gnuplot_demo.css is present, link to it as a stylesheet.

# EAM Aug 2005
# If DEMOTERM is present as an environmental variable, then use
#    set term DEMOTERM
# rather than the default terminal settings
# E.g. (for image demo)
#    setenv DEMOTERM "png truecolor enhanced font 'arial,8' transparent size 450,320"
#    ./webify.pl image
#
# EAM Apr 2009
#    new layout for generated web pages
