autosuspend  is  a  daemon  that  periodically  suspends  a  system  on  inactivity and wakes it up again
       automatically in case it is needed.  For this purpose, autosuspend  periodically  iterates  a  number  of
       user-configurable  activity  checks,  which indicate whether an activity on the host is currently present
       that should prevent the host from suspending.  In case one of the  checks  indicates  such  activity,  no
       action  is  taken  and periodic checking continues.  Otherwise, in case no activity can be detected, this
       state needs to be present for a specified amount of time before the host is suspended by autosuspend.  In
       addition to the activity checks, wake up checks are used to determine planned future  activities  of  the
       system  (for  instance,  a  TV recording or a periodic backup).  In case such activities are known before
       suspending, autosuspend triggers a command to  wake  up  the  system  automatically  before  the  soonest
       activity.

       If  not  specified  via  a  command  line  argument,  autosuspend  looks  for  a default configuration at
       /etc/autosuspend.conf.  autosuspend.conf(5) describes the configuration file, the available  checks,  and
       their configuration options.

Commandlineoptions
       General syntax:
          autosuspend [options] daemon|presuspend|version [subcommandoptions]

   Generaloptions-h,--help
              Displays an online help.

       -cFILE,--configFILE
              Specifies an alternate config file to use instead of the default on at /etc/autosuspend.conf.

       -lFILE,--loggingFILE
              Configure  the  logging  system  with  the  provided  logging file.  This file needs to follow the
              conventions                for                Pythonloggingfiles
              </usr/share/doc/python3-doc/html/library/logging.config.html#logging-config-fileformat>.

       -d     Configure full debug logging in the command line.  Mutually exclusive to autosuspend-l.

   Subcommanddaemon
       Starts the continuously running daemon.

       -a,--allchecks
              Usually,  autosuspend stops checks in each iteration as soon as the first matching check indicates
              system activity.  If this flag is set, all subsequent checks are still  executed.   Useful  mostly
              for debugging purposes.

       -rSECONDS,--runforSECONDS
              If  specified,  do  not run endlessly.  Instead, operate only for the specified amount of seconds,
              then exit.  Useful mostly for debugging purposes.

   Subcommandpresuspend
       Should be called by the system before suspending.

       No options

   Subcommandversion
       Outputs the currently installed version of autosuspend to stdout.
