Kernel patching
===============

To have crtools up and running either 

1) use patches from kernel/ directory
2) or clone git://github.com/cyrillos/linux-2.6.git
   and switch to branch "crtools". Note these patches
   are guaranteed to be up to date only with major
   release of crtool. If you're testing development
   version -- make sure you're applying series from
   kernel/ directory.

It's based on Linux
