## NAME
    [Lingua::Stem::Pt] - Stemming algorithm for Portuguese

## SYNOPSIS
        use [Lingua::Stem::Pt];
        my $stems   = [Lingua::Stem::Pt::stem]({ -words => $word_list_reference,
                                              -locale => 'pt',
                                          -exceptions => $exceptions_hash,
                                         });

## DESCRIPTION
    This routine applies a stemming slgorithm to a passed anon array of
    Portuguese words, returning the stemmed words as an anon array.

    It is a 'convienence' wrapper for '[Lingua::Stemmer::PT]' that provides a
    standardized interface and caching.

## CHANGES
    2.30 2020.06.20 - Version renumber for module consistency

    1.01 2003.09.28 - Documenation fix

    1.00 2003.04.05 - Initial release

## METHODS
    stem({ -words => \@words, -locale => 'pt', -exceptions => \%exceptions
    });
        Stems a list of passed words using the rules of Portuguese. Returns
        an anonymous array reference to the stemmed words.

        Example:

          my $stemmed_words = [Lingua::Stem::Pt::stem]({ -words => \@words,
                                                      -locale => 'pt',
                                                  -exceptions => \%exceptions,
                                  });

    stem_caching({ -level => 0|1|2 });
        Sets the level of stem caching.

        '0' means 'no caching'. This is the default level.

        '1' means 'cache per run'. This caches stemming results during a
        single call to 'stem'.

        '2' means 'cache indefinitely'. This caches stemming results until
        either the process exits or the 'clear_stem_cache' method is called.

    clear_stem_cache;
        Clears the cache of stemmed words
