"""
Compiles Python files into PYC files using the same
version of Python that we bundle with our standalone builds.
It creates hash-based PYC files in opt level 1 with hash checks
defaulting to off, so we don't have to worry about timestamps or
loading speed hits due to hash checks. (see PEP 552).
We just need to tell modders that they'll need to clear these
cache files out or turn on debugging mode if they want to tweak
the built-in scripts.
