chialisp_stdlib

Use:

pip install chialisp_stdlib

To get the path to the include files, use

from chialisp_stdlib import NIGHTLY_INCLUDE_DIRECTORY
from chialisp_stdlib import STABLE_INCLUDE_DIRECTORY

Note that *_INCLUDE_DIRECTORY is a pathlib.Path and not a str, so if your API expects str-based paths, use str(path) to convert.

And upgrade your API: see PEP519. C'mon, it's 2023 (as of this writing).
