[oe] Use python in variable assigment of a recipe

[Steffen Sledz]

According to the user manual it is possible to use python code in variable assignments by using ${@...}.

I like to use a function (subprocess.check_output) here which requires an import statement. Where do i have to place this import?

And another question. Is it possible to determine the path to the recipe itself from with it?

Thx,
Steffen
