Look ath te PackageBuilder src and the addFromDrl - you'll see there the first bit of code that builds the descr. Also look the DrlParserTest which parses code segments and checks the resulting descrs.

Okay, I took some simple example from Drools examples (HelloWorldExample) and
tried to reverse engineer package object in Eclipse debugger, but looks like
the package object doesn't contain any objects from descr package. I assume I
need to compile that Package object somehow?

Could somebody please point me to the right way in getting solid knowledge of
how can I build custom package descriptor w/o any DRL/XML - but from my custom
rule descriptors/storage?

Thank you in advance!
