# Usage:
#   In a CMS or LMS container,
#   from the directory /edx/app/edxapp/edx-platform, run:
#     ./scripts/update-assets-dev.sh
#
# This file is an experimental re-implementation of the asset complation process
# defined by the pavelib.assets:update_assets task in
# https://github.com/edx/edx-platform/blob/master/pavelib/assets.py.
# As the script name implies, it is only suited to compile assets for usage
# in a development environment, NOT for production. 
#
# It was written as part of the effort to move our dev tools off of Ansible and
# Paver, described here: https://github.com/edx/devstack/pull/866
# TODO: If the effort described above is abandoned, then this script should
# probably be deleted.
