"""Build GaCy Go for Android and package its runtime data.

Usage: python tools/package_go_runtime.py PATH_TO_GAC_GO
The source checkout is read only; its current source/resources are packaged.
Mutable saves are seeded from the checkout's committed defaults, never from
the operator's live working files.
