       grandfatherclock plays audio files to sound the nearest hour or quarter
       as directed.  Command line arguments and an optional configuration file
       determine the location of the audio files, and  the  commands  to  play
       them.   The  file  is  usually executed every hour or quarter hour by a
       cron(1) job.


       Options are set by reading an  optional  configuration  file  and  then
       modifying  options  set  by  command  line arguments.  No more than one
       configuration file is read.  The configuration file name is  the  first
       of: the one named in the command line, the one named in the environment
       variable, the first readable one named in the FILES section.
