;;; ========================================
;;;
;;; ... This file is also part of GNU MediaGoblin, but we're leaving it
;;; under GPLv3 for easy merge back and forth between Guix proper.  It
;;; also borrows some code directly from Guix.
;;;
;;; ========================================
;;; 
;;; With `guix environment' you can use guix as kind of a universal
;;; virtualenv, except a universal virtualenv with magical time traveling
;;; properties and also, not just for Python.
;;;
;;; Ok, here's how to use this thing!  First, install Guix.
;;; Then do:
;;;   guix environment -l guix-env.scm --pure
;;;
;;; And the first time you use it:
;;;   ./bootstrap.sh
;;;   ./configure --with-python3 --without-virtualenv
;;;   make
;;;   virtualenv . && ./bin/python setup.py develop  --no-deps
;;;
;;; ... wait whaaat, what's that last line!  I thought you said this
;;; was a reasonable virtualenv replacement!  Well it is and it will
;;; be, but there's a catch, and the catch is that Guix doesn't know
;;; about this directory and "setup.py dist" is technically necessary
;;; for certain things to run, so we have a virtualenv with nothing
;;; in it but this project itself.
;;;
;;; So anyway, now you can do:
;;;  PYTHONPATH="${PYTHONPATH}:$(pwd)" ./runtests.sh
;;;
;;; Now notably this is goofier looking than running a virtualenv,
;;; but soon I'll do something truly evil (I hope) that will make
;;; the virtualenv and path-hacking stuff unnecessary.
;;;
;;; Have fun!
