Just for clarity, I have something like:

... in p.g

class P extends Parser;
options {
  exportVocab = P;
  importVocab = L;
}
rule
   : "keyword" DASH "modifier"
   ;


... in l.g

class L extends Lexer;
options {
  exportVocab = L;
  importVocab = P;
}

DASH
   : '-'
   ;


... and I am attempting to use antlr.Tool to compile them, and it
whinges at me if I give >1 grammar file to compile.

thanks,
David.
