Installation Notes:

First make sure that the mathlink.h header file and the ML32i3 (for 32-bit 
systems) or ML64i3 (for 64-bit systems) library are in places that can be 
found by GHC.

Otherwise, the usual rules apply:

> runhaskell Setup.lhs configure
> runhaskell Setup.lhs build
> [sudo] runhaskell Setup.lhs install
