simple import hook

[DevPlayer]

And for an insane amount of what REALLY gets imported:

python.exe -B -s -S -v -v -v -v your_module_here.py %1 %2 %3 %4 %5 %6
%7 %8 %9

or more appropiately:

python -v -v -v -v your_module_here.py


And for completeness, if you feel those options aren't telling the
whole truth, you can turn on your operating system's file auditing for
opens and reads; I forget if there are other places that can be
imported from besides *.py, *.pyo, *.pyc, *.pyd files too (maybe
zips?)
