"""
|
|
Check dependencies and give recommendations about how to satisfy them
|
|
|
|
Limitations:
|
|
|
|
* Does not detect whether packages are already installed. Solving this requires writing more of a configuration
|
|
management system. Or we could switch to an existing one.
|
|
* Not fully PEP508 compliant. Not slightly. It makes bold assumptions about the simplicity of the contents of
|
|
EXTRAS_REQUIRE. This is fine because most developers do, too.
