Definitive list of part-of-speech tags?

[lrperlmu]

This is a great parser, thanks for sharing it!

Just wondering if you could include or link to a list of all the part-of-speech tags used and their descriptions (similar to this). I've been asking the internet, but haven't yet found a list that has all the tags that show up in pyStatParser, so I have to look up each one individually. Thank you!
