In the version of PPrint that I use, there is a license notice in the
documentation (pprint.html). I just copied that notice into the PPrint.hs
file before using it in my own projects, like so:

Of course, the last word is with Daan Leijen, but I think you should be
legally in the clear doing it that way. It is pretty obvious that, while the
license is in the documentation, it is meant to apply to the code.
