- Part of gif2png (the file 437_l1.c) was generated by the `trans'
- program written by Kosta Kostis <kosta@live.robin.de>. This package
- (a great source for character conversion tables) is available as
- ftp://ftp.uni-erlangen.de/pub/doc/ISO/charsets/transXXX.tar.gz
- where XXX is replaced by a version number.
- The PNG specification is available from
- <http://www.cdrom.com/png/>. Obviously, without the PNG effort this
- program wouldn't have been possible or necessary (or even
- conceivable).
