[Serusers] New route graph utility

Hello, in case you are not following the CVS commit log messages: I just checked in a small python script which should be able to print a dependency graph in ASCII of the route blocks of a SER config file. When you try to understand more complex configuration files this tool might be helpfull. But be warned: this is still alpha code! It will not eat your config file, but the output might not meet your expectations :-) If you run it with the default configuration file the output will look like this: ./route_graph.py ../../etc/ser.cfg Main | \- 1 | \- 1 | \- 1 | \- 1 A more complex scenario (from a config with named routes) could look like this: ./route_graph.py ./ser.cfg Main | \- ROUTE_RPC | | | \- ROUTE_ERROR_REPLY | \- ROUTE_PROXYINIT | | | \- ROUTE_ERROR_REPLY | \- ROUTE_INDIALOG | | | \- ROUTE_ERROR_REPLY | | | \- ROUTE_ST | | | \- ROUTE_FORWARD | | | | | \- ROUTE_LI | | | | | \- ROUTE_RTPPROXY | | | | | \- ROUTE_RR | \- ROUTE_DOMAINPOLICY | | | \- ROUTE_ERROR_REPLY | \- ROUTE_REGISTRAR | | | \- ROUTE_ERROR_REPLY | \- ROUTE_AUTHENTICATION | | [... omitted bigger parts...] Send routes ----------- onsend Failure routes -------------- FAILURE_ROUTE | \- ROUTE_RTPPROXY | \- ROUTE_VOICEMAIL | | | \- ROUTE_SEMS | | | | | \- ROUTE_LI | | | | | \- ROUTE_RR | | | \- ROUTE_ERROR_REPLY | [... omitted bigger parts...] Onreply routes -------------- REPLY_ROUTE Feedback is welcome. Patches even more! :-) Greetings Nils
