"""
This module provides a port of the Snowball stemmers developed by Martin
Porter.

At the moment, this port is able to stem words from fourteen languages: Danish,
Dutch, English, Finnish, French, German, Hungarian, Italian, Norwegian,
Portuguese, Romanian, Russian, Spanish and Swedish.

The algorithms have been developed by Martin Porter. These stemmers are called
Snowball, because he invented a programming language with this name for
creating new stemming algorithms. There is more information available at
http://snowball.tartarus.org/
