Event Publisher =============== ``comet-sendvo`` is a simple event publisher: it forwards messages from an author to a broker. After installation, it should be possible to execute ``comet-sendvo`` directly from the command line. Use the ``--help`` option to display a brief usage message:: $ comet-sendvo --help Usage: comet-sendvo [options] Options: -h, --host= Host to send to. [default: localhost] -p, --port= Port to send to. [default: 8098] -f, --file= Where to read XML text (- is stdin). [default: -] --version Display Twisted version and exit. --help Display this help and exit. Basic usage is straightforward: simply supply ``comet-sendvo`` with the details of the broker to connect to using the ``--host`` and ``--port`` options (or accept the defaults), and give it the text of a VOEvent either directly on standard input or by giving the path to a file. For example:: $ comet-sendvo --host=remote.invalid --port=8098 < voevent_to_publish.xml Or:: $ comet-sendvo -h remote.invalid -f voevent_to_publish.xml
