#With thanks to Ray Pereda (who ported the Perl code to Ruby) I  
#have released a Stemmer gem which contains the Porter word stemming  
#algorithm. Both Lucas Carlson and I were using this code in our  
#Bayesian classifier projects, I have used it in another  
#project and I'm sure other people make use of it too. It made  
#sense to Lucas and I to separate it out into a Gem to make it  
#easier for others to use.
