automatic shutdown as command line option

[stepp]

Hello !
I would like to start the bsplayer so that it automatically
shuts down the computer after playing a video
- but only once.

It would be nice to have two smarticons: one for
starting with automatic shutdown and one for starting
the player without the option.

Maybe there is a command line option for starting with
automatic shutdown.

However I didn't find any lists explaining the command
line options.

Regards - S.
