Jam (like Make)
By Perforce; My notes on building a Mac jam, Bjam looks like a promising offshoot. Their documentation made me understand that “Jambase” is not the name of a file that the user must write, but a particular file provided with the system. Jambase is user modifiable and written in the same language that the user uses for his own specific work.

gcc info

Here are some web pages of information on gcc. I don't know which are more recent or which may keep up to date. I would like any info on that matter.

The main page, and manuals.
Delorie does free software and has a gcc page.
