- History
- This program was written by a German university student named Alexander
- Lehmann <alex@hal.rhein-main.de> in 1995. He evolved it to a beta
- version 0.6 and then dropped off the face of the net. In Fall 1999,
- after the program had been stable and in production use for four years,
- Greg Roelofs <newt@pobox.com> added some minor features and released 0.7.
- A short time later, with Greg's consent, I took over maintaining
- gif2png in order to give it a proper manual page and release
- packaging. Alexander Lehmann is OK with this and has even approved
- a change in the license terms to use the libpng/zlib license.
