After consultation with the pig committers, I've put together a page on
pig philosophy. No, this isn't Aristotle's comments about swine. It's
a page that lays out the guiding principles behind pig. This is
intended to help users and developers understand what pig is and what
it aspires to be. It is also intended to guide committers when making
decisions about what to put into pig. Any feedback you have would be
welcome.
