I'm unsure what the different between the User Guide and User Manual
are, is one just a newer version? Its probably best to just put the
latest one under Help/Contents, or you start to confuse people - the
last thing you want is to have to find help to find how to find help!

Libraries I would say yes. Haskell Report is a bit too dense for most
people who are learning, and those who aren't can find it themselves
from Haskell.org - its rare to read the report. Does Hugs tend to ship
with documentation on the libraries installed?

Thanks
