If the Main module imports System.Environment, you can get this effect via

	Main> withArgs ["arg1","arg2"] main

(there's withProgName too)

That seems to imply that the \* feature isn't working under Windows, so
none of the packages are available.  Can you load Distribution.Simple?
(But it does work when built with MSYS+MinGW, as does HGL itself.)

You also need MSYSdtk.  The commands to build winhugs aren't in the
Makefile yet.  By hang, I mean it doesn't even create a window.

There's nothing in the Makefile, but I understand xsltproc can generate
it from the .xml files.

There's also the MSI packaging.  Sigbjorn, are you there?
