I was wondering since there�s loads of useful stuff in there it seems, but there's little documented on what goodies there are or what they do

Most of them are used by the build process, and are named reasonably self-descriptively, so between the name, comments in the script, and how they are used by the Makefiles and other scripts are fairly easy to figure out. For the most part, they're well within the range of "If you know enough about Linux to be poking around in the kernel source, you almost certainly know enough to be able to figure it out on your own". One that's not directly used in the build process, but still mind-bogglingly useful if you're planning to write patches or post questions about specific files is get_maintainer.pl. If there's a specific script whose function or purpose stumps you even after you've tried all the obvious stuff, let us know and we'll fill in the blanks.
