PUBLIC MARKS from ogrisel with tags java & opennlp

I found a great set of tools for natural language processing. The Java package includes a sentence detector, a tokenizer, a parts-of-speech (POS) tagger, and a treebank parser. It took me a little while to figure out where to start so I thought I'd post my findings here. I'm no linguist and I don't have previous experience with NLP, but hopefully this will help some one get setup with OpenNLP.
