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