## Usage
# ${paperless}/bin/paperless wraps manage.py
# ${paperless}/share/paperless/setup-env.sh can be sourced from a
# shell script to setup a Paperless environment
# paperless.withConfig is a convenience function to setup a
# configured Paperless instance. (See ./withConfig.nix)
# For WSGI with gunicorn, use a shell script like this:
# let
# pythonEnv = paperless.python.withPackages (ps: paperless.runtimePackages ++ [ ps.gunicorn ]);
# in
# writers.writeBash "run-gunicorn" ''
# source ${paperless}/share/paperless/setup-env.sh
# PYTHONPATH=$paperlessSrc ${pythonEnv}/bin/gunicorn paperless.wsgi
# ''
