[Snowball-discuss] less than zero (enriching Italian stemmer)

[Martin Porter]

Adriano,

Yes, you alter the .sbl file, compile the snowball compiler, and translate
the .sbl file into C or java. If you're a software beginner I suggest you
get local help if you can. This will be easier than trying to take you
through the steps from the snowball-discuss board.

I'm not quite sure where python comes into all this ...
