Handle KeyboardInterrupt gracefully rather the printing a backtrace. Most users of these tools don't expect a backtrace when then hit Ctrl-C. Also, fix a few other inconsistencies found in the python startup code of these different scripts: - always call main function 'main' (rather than 'Main') - always return 0 from main function - if main takes args never include argv[0] Review URL: https://codereview.chromium.org/955993006 git-svn-id: svn://svn.chromium.org/chrome/trunk/tools/depot_tools@294250 0039d316-1c4b-4281-b951-d872f2087c98

"""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)."""
