'''
This script demonstrates deleting a repository from disy Cadenza using the API key
authentication of the Cadenza Management API.

This script imports the functions `build_mgmt_api_request_url` and
`sign_mgmt_api_request_url` from the file `cadenza_api_util.py` provided as part
of the developer documentation. Make sure to have both files in the same folder.
