"""This script is a wrapper around the GN binary that is pulled from Google
|
|
Cloud Storage when you sync Chrome. The binaries go into platform-specific
|
|
subdirectories in the source tree.
|
|
|
|
This script makes there be one place for forwarding to the correct platform's
|
|
binary. It will also automatically try to find the gn binary when run inside
|
|
the chrome source tree, so users can just type "gn" on the command line
|

(normally depot_tools is on the path)."""
