To install (as root):

$ python setup.py

If you are using Ubuntu you may need to install python*-dev.

To distribute with your application, simply copy the pgpu/ tree into the main 
dir of your application.

You may wish to do this for two reasons:

1) Not everyone has PGPU installed, therefore if you ship it, your users won't 
   have to install it themselves.

2) Shipping PGPU locks in features and locks out new bugs.
