Description:

This is the Jam/MR program as published by Perforce.

A powerful and highly customizable utility to build programs
and other things, that can run on Un*x, Nt, VMS, OS/2 and
Macintosh MPW, using portable Jamfiles. It can build large
projects spread across many directories in one pass.

It takes some time to fully apprehend, especially when one's
already accustomed to make(1), but there's no comparison in
power when comparing these 2 tools.

Standard rules:
- can automatically extract header dependencies for C/C++ (you can
customize for you own language)
- provide for automatic "clean", "install", "uninstall" rules,
so that an automake-like tool is not needed
