porter.js

=========

[Martin Porter's stemmer](http://tartarus.org/~martin/PorterStemmer/) wrapped

in CommonJS for use in node.js. 

Dr Porter explains the stemmer thus:

> The Porter stemming algorithm (or ‘Porter stemmer’) is a process for removing

> the commoner morphological and inflexional endings from words in English. Its

> main use is as part of a term normalisation process that is usually done when

> setting up Information Retrieval systems.

This is merely a wrapping of work done by others.   The initial javascript port

was done by "Andargor" with substantial revisions by Christopher McKenzie.  More

information is available on Porter's site via the link given above.
