dbus-tests 1.12.0-1ubuntu1 (ppc64el binary) in ubuntu bionic

 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 automated and manual tests for D-Bus, and the
 dbus-test-tool utility. It also provides copies of the D-Bus libraries and
 executables compiled with extra debug information and logging.
 .
 See the dbus package description for more information about D-Bus in general.
