-/**
- * @file testing/gnunet-testing-run-service.c
- * @brief tool to start a service for testing
- * @author Florian Dold
- *
- * Start a peer, running only the service specified on the command line.
- * Outputs the path to the temporary configuration file to stdout.
- *
- * The peer will run until this program is killed,
- * or stdin is closed. When reading the character 'r' from stdin,
- * the running service is restarted with the same configuration.
- *
- * This executable is intended to be used by gnunet-java, in order to reliably
- * start and stop services for test cases.
