2.17:
Changes: This release finishes the numbered lists. All tools have
a 'Close' button now. The configurable resources mechanism now
works without X11 for command line calls. There is preliminary
support for 'shapes', the newer Word figures mechanism. There is
support for the Euro sign if the font supports it. With some
configuration,
Ted can now use most fonts configured in GhostScript. It uses more
CSS and fewer tables in HTML. Many annoying bugs were fixed.
