freesmartphone.org D-Bus XML specification & documentation

 The Desktop-Bus prepares applications to communicate with another
 by the sending of predefined signals. The process is agnostic about
 programming languages, but the collaborating tools need to agree on a
 common set of signals and their interpretation. This package provides
 the DBus specifications of the freesmartphone.org software stack that is
 targeted for smartphones. Process these with a D-Bus binding generator
 to create stubs for your program.
