Configuration Menu Language

From Wikipedia, the free encyclopedia

Configuration Menu Language was used, before compilation of older versions of the Linux kernel, to configure the set of values that will determine the composition and exact functionality of the kernel. Wide variations in kernel functionality exist; a particular kernel can be customized for the exact hardware it will run on and it can be tuned by indicating preference for one behavior over another.

CML was originally written by Raymond Chen in 1993.^[1]

A replacement system for the original Configuration Menu Language was developed by Eric S. Raymond and named CML2 (for Configuration Menu Language 2), but has been officially rejected^[2] by the core Linux kernel team.

The LinuxKernelConf system replaced CML in kernel version 2.5.45, and remains in use for the current 2.6 kernel.^[3]

Anybody remember that? The developer there also got rejected, the improvement was made differently (and much more in line with existing practices and maintainership), and life went on.”
