Re: [Caml-list] Dypgen C++ grammar

["Lukasz Dobrek" <dobrek@gmail.com>]

Hi,
as a side question sort of related to the topic, has anybody written perhaps a
parser for Fortran. I am every once a while forced to write some
numerical code in Java ( no comments please, I know ). I would like
to have a version of f2java, as adapting the output of f2c is a pain.

Regards,
Lukasz
