# Helper script for commands related to the CS Unplugged repository.
#
# Notes:
#  - Changes to template only require user to refresh browser.
#  - Changes to static files require the 'static' command to be run.
#  - Changes to Python code are detected by gunicorn and should take effect
#    on the server after a few seconds.
#
# Future plans:
#  - Start systems when a command is given (for example: 'static') when the
#    development system has not yet been started.
#  - When 'start' is run open website in default browser without creating
#    new terminal prompt.
