apngopt - optimize animated PNG image files

=head1 SYNOPSIS

  apngopt <INPUT *.gif> [<OUTPUT *.png>]

=head1 DESCRIPTION

After converting impage to APNG with e.g. gif2apng(1), the files size
can further be reduced with this utility.

The Animated Portable Network Graphics (APNG) file format is an
extension to the Portable Network Graphics (PNG) specification. It
allows for animated PNG files that work similarly to animated GIF
files, while retaining backward compatibility with non-animated PNG
files and adding support for 8-bit transparency and 24-bit images.
