"""Check Imports Script.

Quickly verify that a list of Python files can be loaded by the Python interpreter
without raising any errors. Ran before running more expensive tests. Useful in
Makefiles.

If loading a file fails, the script prints the problematic filename and the detailed
error traceback.
