USAGE__description="
	A program which automatically connects to any available connections
	described in the configuration file.
	  (configure with 'scwrypts remote configure')

	The omni-session is running it's own wrapper TMUX server with a special
	config. In the wrapper session, 'M-s' is overwritten as the prefix.
	Switch between connections by using 'M-s' followed by the session ID
	number (or use any other default default tmux navigation command). Full
	configuration can be found here:
	  - $SCWRYPTS_ROOT__remote/omni/tmux.conf

	Shut-down the omni-session by pressing 'M-Q' (Q not q! ALT + SHIFT + Q)

	Disconnect (but leave the session running) with 'M-s, d'

	A background process periodically attempts to refresh lost connections.
	Immediate retry can be forced with 'M-R'.
	
	Running this command in an existing tmux session will likely result
	in an infinite loop, so:
	  - don't run the omni-session in a TMUX session
	  - don't connect to the omni-session directly (always use this scwrypt)
