      3 This is largely ripped from somebar's ipc patchset; just with some personal modifications.

      8       This protocol allows clients to update and get updates from dwl.

     10       Warning! The protocol described in this file is experimental and
     11       backward incompatible changes may be made. Backward compatible
     12       changes may be added together with the corresponding interface
     13       version bump.
     14       Backward incompatible changes are done by bumping the version
     15       number in the protocol and interface names and resetting the
     16       interface version. Once the protocol is to be declared stable,
     17       the 'z' prefix and the version number in the protocol and
     18       interface names are removed and the interface version number is
     19       reset.
