[ale] lexx/yacc (flex/bison) book recommendation?

[Alan Stewart]

We've written a fairly complex parser using flex/bison (GNU equivalents 
to lex/yacc). I didn't have time to read the book myself so hired a 
contractor to learn it, and learned a good bit myself from 
observing/debugging/upgrading his work. Since this project was started 
I've since learned of other tools I should have researched before going 
the flex/bison route: ATNLR (http://www.antlr.org/) and Spirit 
(http://www.boost.org/libs/spirit/index.html).

The contractor used O'Reilly's book, I mostly used the flex/bison info 
pages. I think the biggest weakness of the O'Reilly book was that it 
covers lex/yacc. The GNU versions of these programs are not 100% 
identical to the versions covered in the O'Reilly book.
