::
::  Accepts an optional argument of a list of one or more desks, returns info
::  on all desks if no desks are specified.
::
::  Keyword arguments include =filt and =verb. =filt takes one of %running,
::  %suspended, %exists, %exists-not, or %blocking; =verb takes either & or |

::  the desks from the list that match the filter, with the exception of the
::  %blocking filter which always returns all desks that match.
