How to Customize

Copy the default_config.sh file to config.sh in the scripts directory.
Make any necessary edits there, the script will pick up config.sh over default_config.sh.

How to Update

The configuration script is versioned with the variable CONFIG_FILE_VERSION. Any time that the configuration format is changed in default_config.sh, this value is bumped. Once this happens config.sh must be updated manually from the default file to ensure the new/changed variables are as desired. Once the merge is complete the config.sh file's CONFIG_FILE_VERSION should match the default and the build will run.
