Release packaging using automake/autoconf This program was written by a German university student named Alexander Lehmann <firstname.lastname@example.org> 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 <email@example.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. This code was totally stable between 2004 and 2009, so it lay dormant in a bunch of RCS files for six years before being converted to a more modern VCS. If you really care about the release dates for all the ancient versions, you can deduce them by mining the tagged versions.
