[ptp-dev] ANTLR licensing issues

[Craig Rasmussen <crasmussen@xxxxxxxx>]

At the last PTP telecon, Doug brought up the unpleasant possibility  
that we may not be able to use ANTLR because of licensing issues.  As  
we are rather far along with the Fortran 2003 grammar, this would be  
unfortunate.  Chris Rickett and I have been discussing the  
possibility of replacing the ANTLR runtime if there are licensing  
issues with it.  Fortran lexing is problematic anyway, so it wouldn't  
be too far out of bounds for us to replace the whole runtime.

My question is, is there any licensing issues with the EPL using  
ANTLR generated files (both parser and lexer) and not the runtime  
(jar files)?

Cheers,
Craig
