Hey,

I'm attaching:
* the eclass updated according to suggestion from scarabeus,
* the diff between the first revision and the current one.

Changes include:
* moving EAPI check to the global scope,
* moving documentation around,
* passing parameters to inner functions (inherited from base.eclass).

Please review this one, if there are no objections we'd like to introduce it 
to the tree in about two weeks time starting from now.

Thanks a lot,
Dominik
