* debian/control:
  - Drop Vcs-Bzr and update maintainer; this is in universe, not maintained
    by the Desktop Team.
* debian/patches/debian-changes-3.2.2-0ubuntu1:
  - Dropped, looks like an accidental change

<p>
72
 
<a class="link" href="CheeseCameraDeviceMonitor.html" title="CheeseCameraDeviceMonitor"><span class="type">CheeseCameraDeviceMonitor</span></a> provides a basic interface for
73
 
video4linux device enumeration and hotplugging.
74
 
</p>
75
 
<p>
76
 
It uses either GUdev or some platform specific code to list video
77
 
devices.  It is also capable (right now in linux only, with the
78
 
udev backend) to monitor device plugging and emit a
79
 
CheeseCameraDeviceMonitor::added or
80
 
CheeseCameraDeviceMonitor::removed signal when an event happens.
