Please review my inclusion of your suggestions. Additionally I move to
src_prepare to be more binpackage compatible as things are only of
interest at compile time.
commit 366a690925f5cc5e4bdd2ea984d9ccca65d8f996
Author: Justin Lecher <jlec@gentoo.org>
Date: Wed Nov 28 11:54:16 2012 +0100
Be bin package friendly
Move standard call of cuda_sanitize to src_prepapere as it isn't need
for bin packages.

Author: Justin Lecher <jlec@gentoo.org>
Date: Wed Nov 28 11:24:16 2012 +0100
Implemented comments from g-dev review
* Fix whitespacing
* Fix man pages tags
* Try to do things in functions instead of global scope
* remove _ from local variables
* inline check for presents and functionality of cuda-config
