 Open a mixer device and return an OSS mixer device object.  
 \var{device} is the mixer device filename to use.  If it is
 not specified, this module first looks in the environment variable
 \envvar{MIXERDEV} for a device to use.  If not found, it falls back to
-\file{/dev/mixer}.  You may specify \code{'r'}, \code{'rw'} or
-\code{'w'} for \var{mode}; the default is \code{'r'}.

-% If so this argument and the code that handles it should be ripped out.
