Snapshot 0.2.0 (2005-02-15 Carl Worth <cworth@cworth.org>)
==========================================================
Remove all command-line options for generating PNG images, (see
svg2png instead).

Add support for specifying a list of SVG images on the commad-line,
(for slide-show like switching throught images with space/backspace).

Switch from argp to getopt for command-line parsing for better
portability.

Various little fixes.
