#
#   Updated by Michael Radwin (http://www.radwin.org/michael/blog/)
#   on Dec 26th, 2003 to include image size attributes and link
#   titles.
#
# You may distribute this code freely.  It's not rocket science.
#
# Given an OPML file on stdin, produces an XHTML "blgoroll" fragment
# suitable for inclusion on a weblog.  Tested with AmphetaDesk and
# Radio UserLand.
#
# Usage: opml2html.pl < foo.opml > bar.html
