Declare a license in the package metadata (PyPI reports the package as UNKNOWN)

[nuest]

Hi, and thanks for staticmap!

The published package (staticmap 0.5.7) bundles the Apache-2.0 LICENSE.txt, but its distribution metadata declares no license: setup.py passes neither a license= argument nor any License :: classifier (classifiers=[]). Automated license scanners (e.g. pip-licenses) therefore report the package as UNKNOWN.

Declaring the license in setup.py would fix it:

setup(
    ...,
    license="Apache-2.0",
    classifiers=[
        "License :: OSI Approved :: Apache Software License",
    ],
)

This makes the license machine-readable and lets downstream projects verify dependency licenses automatically in CI. Thanks!
