After updating Haskell GHC to Version 7.0.4, wai-handler-devel stopped working, responding with "command not found"

The fix is to add the correct path ($HOME/Library/Haskell/bin) to your .bash_profile

export PATH="$HOME/Library/Haskell/bin;$PATH"

In .bash_profile (or what have you)

function rserve () {
    ruby -rwebrick -e"s = WEBrick::HTTPServer.new(:Port => 3000,  :DocumentRoot => Dir.pwd); trap('INT') { s.shutdown }; s.start"

}

	For each Ruby module/class, we have Ruby methods on the left and the equivalent
	Clojure functions and/or relevant notes are on the right.

	For clojure functions, symbols indicate existing method definitions, in the
	clojure namespace if none is explicitly given. clojure.contrib./ functions can
	be obtained from http://github.com/kevinoneill/clojure-contrib/tree/master,
	ruby-to-clojure./ functions can be obtained from the source files in this
	gist.

	If no method symbol is given, we use the following notation:

	// From: https://github.com/christkv/node-mongodb-native
	// Not picking on the driver itself, it appears to be idiomatic node javascript


	// Custom factory (need to provide a 12 byte array);
	CustomPKFactory = function() {}
	CustomPKFactory.prototype = new Object();
	CustomPKFactory.createPk = function() {
	return new ObjectID("aaaaaaaaaaaa");
	}

	Ideas for light-weight node middleware functions
	Riffing on ideas for weaving functions together in a middleware architecture for node.


	Overview:
	a function that returns a rack-style array of status, headers and body

	Function Requirements:
	access to the environment (essentially the raw node request and response objects)
