usage: strapclean.py <url or socket_path> <rdffile_path_or_url>

Feed an RDF graph to a strap server.
The first argument is either a strap:// URL, or a file:/// URL or path to a
unix socket on which a strap server is listening.

example:
    strapdump.py strap://localhost:1234/path/to/graph my_file.rdf
    strapdump.py /tmp/strap.sock my_file.rdf
