-"""
-Cache built dependencies for builds.

-This script is finding common install directory and either
-packs each folder into a tar.gz archive, if it wasn't packed before,
-or unpacks existing archives.
-
-Expected to be executed from 'build' directory (e.g. that might contain 'Linux/x86_64/install').

-Usage: python cache_dependencies.py [pack|unpack]
