Stallman and Francois Pinard ! They gave me a lot of valueable hints and suggestions to Gcal! Lots of thanks to Kai Uwe Rommel , who did the major part of adapting Gcal to OS/2 systems. Special thanks to the Info-ZIP group (), which merely granted me the permission to use their `version_local()' function of `zip-2.1' in a modified way for Gcal (the `print_compiler_info()' function is based on copyrighted code by the Info-ZIP group). Also special thanks to Helmer Aslaksen for his well written `The Mathematics of the Chinese Calendar' paper that is published via , and his helpful comments and discussion about the Chinese and Japanese calendars. Also thanks to Paul Schlyter for his fine `How to compute planetary positions' and `How to compute rise/set times and altitude above horizon' texts published via and . Thanks to Keith Burnett who publishes a lot of diverse --good quality-- astronomical sources and links at . And lots of thanks to Steven L. Moshier for his great `aa.arc' ephemeris calculation software, which inspired me to implement astronomical functions into Gcal to calculate the various data and times of Sun and Moon.
