That is, the ones that begin with "<jd:"...
The ones directly usable through the UI in JDownloader include orgfilename, orgfiletype, simpledate, orgpackagename, packagename, etc.
I've looked through PackagizerController.java in the source and it should have them all (I guess?) but I'm having trouble figuring out everything and what each one does.
For example, what are these (I think they exist?): append, env, hoster, source, indexof, subfolderbyplugin, orgfilenamewithoutext, prop. How do I use these and what do they do--(orgfilenamewithoutext is self-explanatory, I know)?. There are probably others I've missed (and I am certainly not sure how to use them). A reference/guide would be REALLY helpful
EDIT: Figured out append - it just allows you to tack on additional text to the result of the previous rule(s) (right?)
