Stemmer class is a convenient facade for other stemmer-related classes. The core stemming algorithm and its implementation is taken verbatim from the Egothor project ( www.egothor.org ).

Even though the stemmer tables supplied in the distribution package are built for Polish language, there is nothing language-specific here.
