It's not a great experience now, but hopefully things are moving in
the right direction.

Cabal-install is intended to remove this problem, so that you can say
"i want crypto" and it gets everything that requires.

I've complained about these before, although I don't think anyone
considered doing anything about it.

--prefix should put it where you want. What you really want is a
Windows user interface, which is what I want too.

You can install them with runhaskell Setup haddock, but I have no idea
where they end up. They will be on hackage at some point, with

Complain to the author. I always try and include a manual with at
least one short example of how to use the library to do something
interesting. Unfortunately all these things take time, something that
not everyone has.

Part of the problem is that the number of Windows Haskell developers
is low. Another part of the problem is that some people have scorn and
contempt for Windows. Alas, those things are hard to change.
