This directory contains "package" level scripts which are needed either for building the MC image, or are needed when starting or stopping the image in a container. These are not really a part of the xAPP. encode_json.py -- reads a json file and generates the quoted output suitable for passing on a curl command etc. j2src.py -- parses the config file (descriptor file) to extract info needed at the time the start script is run. xam_register.sh -- sends a register or unregister request to the xAPP manager process. These scripts should all be copied to /playpen/bin in the image.
