new release of LIP prototype API

[Isaac Jones]

Greetings,

I just uploaded a new release of the Library Infrastructure prototype
API for Distribution.Package and the command-line utility
"haskell-config".  The API for package configuration is included
below, FYI.

I'm going to be focusing more on the Build stuff (rather than the
packaging stuff) for a little while, but with luck, this can be near
to finalization soon.

The web page is here:
http://www.haskell.org/libraryInfrastructure/

Feedback and volunteers for coding are always welcome :)

peace,

isaac

ps. I'm using arch (tla) for version control, so if you've been
wanting to check it out, now is a good time :)
