"""Prototype compiler wrapper.
Only tested with: gcc, g++, clang, clang++
Installation instructions:
1. Rename compiler from <compiler_name> to <compiler_name>.real
2. Create symlink from this script (compiler_wrapper.py), and name it
<compiler_name>. compiler_wrapper.py can live anywhere as long as it is
executable.
Design doc:
https://docs.google.com/document/d/1yDgaUIa2O5w6dc3sSTe1ry-1ehKajTGJGQCbyn0fcEM
