Setup
-----
1. Install MPW. The mpw binary should be somewhere in your `$PATH`.
It also checks `/usr/local/bin/mpw` and `$HOME/mpw/bin/mpw`
It also checks `/usr/local/bin/mpw` and `$HOME/mpw/bin/mpw`. You can
use mpw-shell without it but only with builtin commands.
2. Copy the `Startup` script to `$HOME/mpw/`. This script is executed
when mpw-shell (or mpw-make) starts up (imagine that) and should
be used to set environment variables.
Command Line Flags
------------------
-D name=value Define environment variable
-v Be verbose (equivalent to -Decho=1)
-f Ignore the Startup script
-c string Execute string
-h Display help
