The "report_rom" component is both a report service and a ROM service. It makes
incoming reports available as ROM modules. The ROM modules are named after the
label of the corresponding report session.

Configuration
-------------

The report-ROM server hands out ROM modules only if explicitly permitted by a
configured policy. For example:

! <config>
!   <rom>
!     <policy label="decorator -> pointer" report="nitpicker -> pointer"/>
!     <policy ...  />
!     ...
!   </rom>
! </config>

The label of an incoming ROM session is matched against the 'label' attribute
of all '<policy>' nodes. If the session label matches a policy label, the
client obtains the data from the report client with the label specified in the
'report' attribute. In the example above, the nitpicker GUI server sends
reports about the pointer position to the report-ROM service. Those reports
are handed out to a window decorator (labeled "decorator") as ROM module.
