Hi Guix,

I often find myself typing `guix environment -l guix.scm' in the Guix
source root and thought IWBN no make that "just work".  WYDT?

Greetings,
janneke

Developers are encouraged to include a `guix.scm' in the root of their project
source to set-up a development environment (See 4.2 Invoking ‘guix package’),
so that

    guix environment -l guix.scm

provides a development environment.

* guix.scm: Return guix "git" package.
