+Lucene Contrib Analyzers README file
+
+This project provides pre-compiled version of the Snowball stemmers
+based on revision 500 of the Tartarus Snowball repository,
+together with classes integrating them with the Lucene search engine.
+
+A few changes has been made to the static Snowball code and compiled stemmers:
+
+ * Class SnowballProgram is made abstract and contains new abstract method stem() to avoid reflection in Lucene filter class SnowballFilter.
+ * All use of StringBuffers has been refactored to StringBuilder for speed.
+ * Snowball BSD license header has been added to the Java classes to avoid having RAT adding new ASL headers.
+
+
+IMPORTANT NOTICE ON BACKWARDS COMPATIBILITY!
+
+An index created using the Snowball module in Lucene 2.3.2 and below
+might not be compatible with the Snowball module in Lucene 2.4 or greater.
