Currently, the codes are compiled to .pyd files using Cython so I guess they are protected from people who want to see the source code.
However, the problem is that we would like them (the cythonized code) to be unusable without appropriate license files just like any commercial software.
Is there a way for a source code to check for available license files before proceeding to the actual execution? or perhaps any other way to check the user's PC information before allowing execution?
