Description:

The kernel-source package contains the source code files for the Linux
kernel. These source files are needed to build most C programs, since
they depend on the constants defined in the source code. The source
files can also be used to build a custom kernel that is better tuned to
your particular hardware, if you are so inclined (and you know what you're
doing).

!! The tmb kernels is an experimental kernel based on the mdk kernels,
with added patches. Some of them may/will never end up in the main
mdk kernels due to their experimental nature. Some refer to this
kernel as a 'hackkernel' ...
Use these kernels at your own risk !!
