how to run obexd-client and obexd-server.

Hi,
 I have downloaded and installed obexd(which contains) OPP profile from
http://www.kernel.org/pub/linux/bluetooth/

But I am not getting how to run obexd-client and obexd-server.
Please let me know where can I see  sample programs.

I want to know which command line arguments needs to be given to
server and client to "push"  any string,  like "this is a string",
from client to server.

Thanks.
