About GDL: how to help and contribute • Try it! Let us know what you use GDL for. Or if you don’t, why not. • Report feature/improvement requests and bugs (with example codes). • Send patches (GPL code) with new features, bugfixes or test routines. • Port or package GDL for new platforms. • Report problems to packagers. • Let others know about GDL! We need help! • What is really important now is that GDL is User-wish driven project. • We cannot check all the cases: please report! • We don’t know all keywords: please report if missing or misbehaving. • We don’t know or haven’t checked all (sometime crazy) interactions between keywords: please report problems (IDL Documentation is itself not always without ambiguities).
