There is no file fsq.tokens.
This is a message from antlr, so how can I change this?  I didn’t do
anything except creating the three grammar files.  Should I put the line

tokenVocab=fsqLexer;

in faqTreeParser?

Hm, AntlrIDE (for Eclipse) seems to move the Java output files to the
appropriate folder, but leave the tokens file where the grammar is.
This is fine with me.

Aha, invoking antlr from the command line indeed does create the file
fsqParser.tokens.  So this seems to be a bug with AntlrIDE.  Is somebody
from there reading this, or should I report it elsewhere?

Thanks, H.
