It apparently is a file to be be processed by 'cython'.
See, e.g., python-cytoolz and python-pyclipper for how to use 'cython'.

From (guix)Synopses and descriptions:

‘Please avoid marketing phrases such as “world-leading”,
“industrial-strength”, and “next-generation”, and avoid superlatives
like “the most advanced”—they are not helpful to users looking for a
package and may even sound suspicious.  Instead, try to be factual,
mentioning use cases and features.’

'awesome' and 'is fun to use' is marketing, and not very informative.

The file LICENSE isn't the 1-clause BSD.
Rather, it appears to be the 3-clause BSD, with ‘the name of the copyright holder’
removed.

Greetings,
