The Kconfig way


Kconfig/Kbuild is a complex beast
It is a set of Makefile rules and dependencies
Somebody complained that instead of augmenting make, we should replace it
Those developers eventually surrendered and used Kconfig

But the Kconfig language is simple
It is documented in the kernel sources
Documentation/kbuild/kconfig-language.txt
But it's so easy that for most things you can just copy other Kconfig files

You can configure with any out of a range of tools
config, menuconfig, nconfig, qconfig, gconfig, ...

The output is a text file
You can ship configuration examples
And you easily apply a predefined configuration
