# Script to use autossh to open up a remote screen session, or
# reconnect to an existing one. Based on autossh's original rscreen
# example script as installed on Debian systems into
# /usr/share/doc/autossh/rscreen, but with more generally usable
# defaults

Usage: $BASENAME [autossh or ssh options] <host>
If \$RSCREEN_COMMAND is set (either in the environment, in
/etc/${BASENAME}rc, or in ~/.${BASENAME}rc), it will be used instead of screen
or tmux. Use this feature if you want to supply additional screen
options or tmux commands. (Using \$RTMUX_COMMAND does not work!)
