``*************************************************************************
** WARNING: License Definition for the Project is Deprecated **
Briefcase now uses PEP 621 format for license definitions.
Previously, the name of the license was assigned to the 'license'
field in pyproject.toml. For PEP 621, the name of the license is
assigned to 'license.text' or the name of the file containing the
license is assigned to 'license.file'.
The current configuration for the Project has a 'license' field
that is specified as a string:
license = "MIT"
To use the PEP 621 format (and to remove this warning), specify that
the LICENSE file contains the license for the Project:
license.file = "LICENSE"
