This program calls purple API functions using DBus and prints the return value.
If you are not interested in the return value, use purple-send-async.

Usage:

   $0 method-name type1:parameter1 type2:parameter2 ...

This shell script just invokes dbus-send, see man dbus-send for how 
to specify the parameters.  

Examples:

   $0 PurpleAccountsFindConnected string: string:prpl-jabber
   $0 PurpleAccountsGetAll
   $0 PurpleCoreQuit

Use dbus-viewer to get the list of supported functions and their parameters.
