Robert Muir updated LUCENE-2055:
--------------------------------

    Description: 
would like to remove stemmers in the following packages, and instead in their 
analyzers use a SnowballStemFilter instead.

* analyzers/fr
* analyzers/nl
* analyzers/ru

below are excerpts from this code where they proudly proclaim they use the 
snowball algorithm.
I think we should delete all of this custom stemming code in favor of the 
actual snowball package.


{noformat}
/**
 * A stemmer for French words. 
 * <p>
 * The algorithm is based on the work of
 * Dr Martin Porter on his snowball project<br>
 * refer to http://snowball.sourceforge.net/french/stemmer.html<br>
 * (French stemming algorithm) for details
 * </p>
 */

public class FrenchStemmer {

/**
 * A stemmer for Dutch words. 
 * <p>
 * The algorithm is an implementation of
 * the <a 
href="http://snowball.tartarus.org/algorithms/dutch/stemmer.html";>dutch 
stemming</a>
 * algorithm in Martin Porter's snowball project.
 * </p>
 */
public class DutchStemmer {

/**
 * Russian stemming algorithm implementation (see 
http://snowball.sourceforge.net for detailed description).
 */
class RussianStemmer
{noformat}



  was:
would like to mark the following code deprecated, so it can be removed.

* analyzers/fr: all except ElisionFilter, this is unrelated and standalone.
* analyzers/nl:entire package
* analyzers/ru: entire package

below are excerpts from this code where they proudly proclaim they use the 
snowball algorithm.
I think we should delete all of this code in favor of the actual snowball 
package.
