Started real porting effort. The goal is to port one ANTLR runtime class at a time from Java to Perl, including full API coverage and documentation. First stop of the porting train: ANTLR::Runtime::BitSet.

Got the first parser working: SimpleCalc, taken from the Five minute introduction to ANTLR 3.

Hi Ron
I'm interested in leveraging my current Perl infrastructure to produce a DSL for MySQL dataloading and maintenance related tasks.
Very interested in this port. Keep up the good work !
Thank you
