check-system 1.0.0

Tool for checking that a system is ok

Check system

Small cli tool that check system environment markers according to PEP 508 and exits with an error if it is not.

It is meant to be used to abort scripts that are run on the "wrong" system, e.g., a compilation of requirements (with pip-compile) run on a different architecture than the intended use of the requirement file.

The whole library is just one file check_system.py.
