The first line below changes the command key from Ctrl-b to Ctrl-a, to
emulate Gnu screen.

  $ cat ~/.tmux.conf
  set-option -g prefix C-a
  new-session -nlocalhost -sMyFirstTmuxSession
  new-window -d -nfoo -t1
  new-window -d -nbar -t2
  new-window -d -nmail -t3

I started my first session with this command:

  $ tmux attach

And when I detach it, I can resume it again with the same command.

I based the config file above off the following example config, after
some hunting around in the man page.

  $ tail -n12 /usr/share/doc/tmux/example_tmux.conf
  # Create a single default session, because a session is created here, tmux
  # should be started with "tmux attach" rather than "tmux new"
  new -d -s0 -nirssi 'exec irssi'
  set -t0:0 monitor-activity on
  set  -t0:0 aggressive-resize on
  neww -d -ntodo 'exec emacs ~/TODO'
  setw -t0:1 aggressive-resize on
  neww -d -nmutt 'exec mutt'
  setw -t0:2 aggressive-resize on
  neww -d
  neww -d
  neww -d

The modifications were mainly to replace all the aliases in the
/usr/share/doc/ example with the corresponding full command
names. (Seems a bit weird to put abbreviated aliases in a example
meant to provide documentation.)
