MPW Shell
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
MPW Shell is a re-implementation of the Macintosh Programmer's Workshop shell.
|
|
|
|
|
The primary reason is to support MPW Make (which generated shell script). It
|
|
|
|
|
may also be useful for other things.

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`
|
|
|
|
|
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.
