------------------
* DVRs on the current network can now be listed with ``dvr neigh``.
This command does not require a hostname.
* For all other commands, which do require a hostname, it should now be
passed using the ``-h`` option to ``dvr``.
* Live video from camera N can now be obtained by passing ``monitor:N``
to ``dvr cat``. Append ``;hd`` or ``;sd`` to select the corresponding
stream, and mind the shell quoting.
* Sizes are now displayed in GNU 'human-readable' format (2K, 31M, etc.)
using ``humanize`` when ``dvr find`` is given the ``-h`` flag.
