-# This file is (possibly, depending on python version) imported by |
-# gyp_webrtc when GYP_PARALLEL=1 and it creates sub-processes |
-# through the multiprocessing library. |

-# Importing in Python 2.6 (fixed in 2.7) on Windows doesn't search for |
-# imports that don't end in .py (and aren't directories with an |
-# __init__.py). This wrapper makes "import gyp_webrtc" work with |
-# those old versions and makes it possible to execute gyp_webrtc.py |
-# directly on Windows where the extension is useful. |
