# DESCRIPTION
#
# Script to update the files on github for the IMA SDK iOS DAI samples
#
# USAGE
#
# Make sure to update the number in the VERSION file each time you do a release
#
# Run this script without arguments to add a new entry to the github release
# section with an already built bundle:
#
#   ./googlemac/iPhone/InteractiveMediaAds/IMA/ios/samples/DAI/make_release
#
# It will create a zipped up release for ima sdk.
#
# To update the source files and bundled files on GitHub run the following,
# updating the source files is usually done automatically by copybara:
#
#   ./googlemac/iPhone/InteractiveMediaAds/IMA/ios/samples/DAI/make_release --update_mode
#
# To build the sample apps through copybara in a temp directory before pushing to GitHub run:
#
#   ./googlemac/iPhone/InteractiveMediaAds/IMA/ios/samples/DAI/make_release --test_mode
#
# In the rare case you want to pass additional args to copybara, you can use the following:
#
# ./make_release --copybara_args='--init-history' or ./make_release -a='--init-history'
#
# The above example will append the '--init-history' argument when it runs copybara.
#
# NOTES
#
# If you don't run gcert, this thing will throw all kinds of weird piper
# errors.
