# This package was last seen at http://www.tdb.uu.se/~jan/html2ps.html.
# The software wasn't developed anymore, none of my patches were accepted
# therefore I've forked it and add all the patches to this version.
#  
# Currently it's distributed as a component of the bigger package under
# the same license as Perl or GNU GPL, whichever you prefer.
