invenio-initialise-virtualenv

#!/bin/bash
#
# A helper devscript to initialise virtualenv for Invenio development.
# Assumes certain sudo rights.  Typical usage:
#
#   $ cd ~/private/src/invenio
#   $ git checkout master
#   $ mkvirtualenv --system-site-packages invenio-master
#   $ invenio-initialise-virtualenv invenio-master --yes-i-know
#   $ deactivate && workon invenio-master
#   $ invenio-recreate-demo-site --yes-i-know
