Many aspects of

The configuration file is located in the spooler hierarchy

The following options are recognized:
as a configuration parameter specification that is interpreted
after reading the per-device configuration file.
For example, ``-c sessiontracing:0x4f'' would set the
configuration parameter to ``0x4f'', overriding any setting in
the configuration file.

A device identifier is formed from a device filename by removing
any leading ``/dev/'' and converting any ``/'' characters to ``_''
