edge-0.9.1.1: README.md

# README for [`edge` package](http://hackage.haskell.org/package/edge)

There are, unfortunately, a number of complexities and difficulties in the dependency tree, which I think would make it difficult to compile on most platforms. However, it does build on the Debian Jessie release, with ghc-7.6.3 installed:

```sh
sudo apt-get install ghc cabal-install libghc-gloss-dev libghc-alut-dev
cabal update
cabal install edge
~/.cabal/bin/edge
```

If you have already have version of gloss, OpenAL, or GLUT Haskell libraries installed via cabal, you may wish to remove them first with `ghc-pkg unregister gloss` etc.
