It is now on its way and should be available very soon on your nearest CPAN mirror site. You can now generate standalone parser modules, so you don't need anymore the Parse-Yapp module itself to have them run. Francois Desarmenien, all rights reserved.
Comments are welcome too.
Just drop me a mail. If not, I suggest the GNU Bison manual which is a very good tutorial to LALR parsing and yacc's grammar syntax. Any help on this issue would be very welcome. It is written only in Perl, with standard distribution modules, so you don't need any compiler nor special modules. I just hope it can be useful.
