Java to Python translation

[vio]

Greetings,

I need to translate a (rather voluminous 100MB) java program to python. After a
few searches on google, apparently the best tools for this task are Lex-Yacc
(Flex-Bison on linux). While I am working on the Lex-YACC HOWTO, I would be very
interested in hearing of others' successful experiences/feedback at this. Any
pointers of interest would similarily be appreciated.

Many thanks,
Vio
