# You can configure this script in three ways. 
# 1. First, set the variables in this column with more comments. 
# 2. The second is to pass an environment variable via a flag such as --help. 
# 3. The third way is to set the variable externally, or pass it in as an environment variable

# Default configuration for OpenIM Repo
# The OpenIM Repo settings can be customized according to your needs.

# OpenIM Repo owner, by default it's set to "OpenIMSDK". If you're using a different owner, replace accordingly.
