$ brew install frege

Launching `fregec` from the command line will execute `exec java
-Xss1m -jar fregec.jar`, along with any arguments you supply.  For
example:

$ echo 'package helloworld.HelloWorld where

import frege.IO

main :: [String] -> IO ()
main _ = print "Hello, world!"
' >> HelloWorld.fr

$ mkdir classes
$ fregec -d classes HelloWorld.fr

Remember to use Java 7, and enjoy!

Great work, James.
Can't try it out because I don't have no Mac, though.

BTW, when was the last time I saw someone use echo as a program editor?
Closest that comes to mind is "Evolution of a Programmer" where in some
stage the source code is entered with cat >hello.c
:)
