# The specified GitHub URL is used to fetch application code. Applications are created with the specified
# subdomain as <subdomain>.usb.cs.purdue.edu. The passed user ID is associated with the created application
# as a label so that stats fetched for applications can be scoped by user by passing the `-l` flag.

# Usage:
# ./make-new-app <GitHub URL> <desired subdomain (eg. 'foobar')> <Pley dashboard user ID>
#
# eg.
#       ./make-new-app https://github.com/spencer-brown/contact-bump contact-bump 2304awoeijf23i2
