Auto-create processe's output-path?

[Olivier Dion via <gwl-devel@gnu.org>]

Hi,

I think it would be nice if GWL automatically creates the `output-path`
of a process.  

Currently, I have to do the following:
--8<---------------cut here---------------start------------->8---
output-path "output-of"
packages ... "coreutils" ...
# {
  ...
  mkdir {{output-path}}
  ...
}
--8<---------------cut here---------------end--------------->8---

I don't really like this because now I need "coretutils" as a dependency
-- which I tend to reduce to a minimal -- and I also need to manually
call `mkdir` in my script.

Would it be possible for GWL to do this instead?
