# A wrapper for running tmux. Takes on (optional) main session name as
# argument, creates it if it doesn't exist. Then (in either case),
# a new slave session is created and attached to the main session.
# The slave session is configured to be destroyed automatically when
# detached, but the main session stays alive. This arrangement allows
# each slave session to have independent control over active windows/panes.
#
# (Make sure ~/.tmux.conf does not interfere by having something like
#  `new-session` or `attach-session` in it.)
