Re: overriding the filter method

It's not in the copy that I printed. (or on the page you referred me to, or on any of the other pages
in that document.  I did a search for "TKeyword", "token.getLine", and they're not present in
thesis.html.) Page 38 has the syntax for Helpers, States, Tokens, ....  Page 39 has the only filter
example I could find. That code shows how to recognize nested comments.

The TKeyword method looks useful and needs to be documented better. I see (on page 35) that
root.node.TSomeToken is generated by the Lexer, but it's not until page 62 that you mention
get/setLine (but not get/setColumn). Even though the method is mentioned, there doesn't appear to be a
description of what arguments are needed for the TSomeToken constructor. I'm trying to get javadoc to
generate the documentation, but having some trouble getting the details to work under Cygwin with the
NT version of Java.
