python-dbus-dev 1.1.0-1 (i386 binary) in ubuntu quantal

 D-Bus is a message bus, used for sending messages between applications.
 Conceptually, it fits somewhere in between raw sockets and CORBA in
 terms of complexity.
 .
 This package provides development files required to compile main-loop
 integration modules for python-dbus, such as dbus.mainloop.qt provided
 by PyQt. It is Python-version-independent: you must also depend on either
 python-dbus or python3-dbus, if required.
