+## What should I do before opening an issue?
+
+Before opening an issue, please ensure that:
+
+- Your problem is a specific problem or question or suggestion, not a general
+  complaint.
+
+- `$TERM` inside tmux is screen, screen-256color, tmux or tmux-256color. Check
+  by running `echo $TERM` inside tmux.
+
+- You can reproduce the problem with the latest tmux release, or a build from
+  Git master.
+
+- Your question or issue is not covered [in the
+  manual](https://man.openbsd.org/tmux.1) (run `man tmux`).
+
+- Your problem is not mentioned in [the CHANGES
+  file](https://raw.githubusercontent.com/tmux/tmux/master/CHANGES).
+
+- Nobody else has opened the same issue recently.
+
+## What should I include in an issue?
+
+Please include the output of:
+
+~~~bash
+uname -sp && tmux -V && echo $TERM
+~~~
+
+Also include:
+
+- Your platform (Linux, OS X, or whatever).
+
+- A brief description of the problem with steps to reproduce.
+
+- A minimal tmux config, if you can't reproduce without a config.
+
+- Your terminal, and `$TERM` inside and outside of tmux.
+
+- Logs from tmux (see below).
+
+- At most one or two screenshots, if helpful.
+
+## How do I test without a .tmux.conf?
+
+Run a separate tmux server with `-f/dev/null` to skip loading `.tmux.conf`:
+
+~~~bash
+tmux -Ltest kill-server
+tmux -Ltest -f/dev/null new
+~~~
+
+## How do I get logs from tmux?
+
+Add `-vv` to tmux to create three log files in the current directory. If you can
+reproduce without a configuration file:
+
+~~~bash
+tmux -Ltest kill-server
+tmux -vv -Ltest -f/dev/null new
+~~~
+
+Or if you need your configuration:
+
+~~~base
+tmux kill-server
+tmux -vv new
+~~~
+
+The log files are:
+
+- `tmux-server*.log`: server log file.
+
+- `tmux-client*.log`: client log file.
+
+- `tmux-out*.log`: output log file.
+
+Please attach the log files to your issue.

+# Welcome to tmux!
+
+tmux is a terminal multiplexer: it enables a number of terminals to be created,
+accessed, and controlled from a single screen. tmux may be detached from a
+screen and continue running in the background, then later reattached.
+
+This release runs on OpenBSD, FreeBSD, NetBSD, Linux, OS X and Solaris.
+
+## Dependencies
+
+tmux depends on [libevent](https://libevent.org) 2.x, available from [this
+page](https://github.com/libevent/libevent/releases/latest).
+
+It also depends on [ncurses](https://www.gnu.org/software/ncurses/), available
+from [this page](https://invisible-mirror.net/archives/ncurses/).
+
+## Installation
+
+### From release tarball
+
+To build and install tmux from a release tarball, use:
+
+~~~bash
+./configure && make
+sudo make install
+~~~
+
+tmux can use the utempter library to update utmp(5), if it is installed - run
+configure with `--enable-utempter` to enable this.
+
+### From version control
+
+To get and build the latest from version control - note that this requires
+`autoconf`, `automake` and `pkg-config`:
+
+~~~bash
+git clone https://github.com/tmux/tmux.git
+cd tmux
+sh autogen.sh
+./configure && make
+~~~
+

-******************************************************************************
-
-* How is tmux different from GNU screen?
-
-tmux and GNU screen have many similarities. Some of the main differences I am
-aware of are (bearing in mind I haven't used screen for a few years now):
-
-- tmux uses a client-server model. Each server has single Unix domain socket in
-  /tmp and within one server there are multiple sessions which may be attached
-  to multiple clients (terminals).
-
-  This has advantages, notably: windows may be linked simultaneously to
-  multiple sessions; windows may be moved freely between sessions; and a client
-  may be switched between sessions easily (C-b D). There is one major
-  disadvantage: if the server crashes, game over, all sessions die. In
-  practice, however, tmux is quite stable and gets more so as people report any
-  bugs they hit :-).
-
-  This model is different from screen, where typically each new screen instance
-  is independent. tmux supports the same behaviour by using multiple servers
-  with the -L option but it is not typically recommended.
-
-- Different command interfaces. One of the goals of tmux is that the shell
-  should be easily usable as a scripting language - almost all tmux commands
-  can be used from the shell and behave identically whether used from the
-  shell, from a key binding or from the command prompt. Personally I also find
-  tmux's command interface much more consistent and clearer, but this is
-  subjective.
-
-- tmux calls window names (what you see in the status line) "names", screen
-  calls them "titles".
-
-- tmux has a multiple paste buffers. Not a major one but comes in handy quite a
-  lot.
-
-- tmux supports automatically renaming windows to the running application
-  without gross hacks using escape sequences. Its even on by default.
-
-- tmux has a choice of vi or emacs key layouts. Again, not major, but I use
-  emacs so if tmux did support only one key set it would be emacs and then all
-  the vi users would get humpy. Key bindings may be completely reconfigured in
-  any case.
-
-- tmux has an option to limit the window size.
-
-- tmux has search in windows (C-b f).
-
-- The window split (pane) model is different. tmux has two objects, windows and
-  panes; screen has just windows. This difference has several implications:
-
-  * In screen you can have a window appear in several layouts, in tmux a pane
-  can only be in one window (fixing this is a big todo item but quite
-  invasive).
-
-  * tmux layouts are immutable and do not get changed unless you modify them.
-
-  * In tmux, all panes are closed when you kill a window.
-
-  * tmux panes do not have individual names, titles and so on.
-
-  I think tmux's model is much easier to manage and navigate within a window,
-  but breaking panes off from and joining them to windows is more clumsy.
-
-  tmux also has support for preset pane layouts.
-
-- tmux's status line syntax is more readable and easier to use. I think it'd be
-  hard for anyone to argue with this. tmux doesn't support running a command
-  constantly and always using the last line of its output, commands must be run
-  again each time.
-
-- tmux has modern, easily extended code. Again hard to argue screen is better
-  if you have looked at the code.
-
-- tmux depends on libevent. I don't see this as a disadvantage: libevent is
-  small and portable, and on modern systems with current package management
-  systems dependencies are not an issue. libevent brings advantages in code
-  simplicity and performance.
-
-- screen allows the window to be bigger than the terminal and can pan around
-  it. tmux limits the size to the largest attached client. This is a big todo
-  item for tmux but it is not trivial.
-
-- screen has builtin serial and telnet support; this is bloat and is unlikely
-  to be added to tmux.
-
-- screen has support for updating utmp. Nobody has really come up with a clean,
-  portable way to do this without making tmux setuid or setgid yet.
-
-- Environment handling is different.
-
-- tmux tends to be more demanding on the terminal so tends to show up terminal
-  and application bugs which screen does not.
-
-- screen has wider platform support, for example IRIX, and for odd terminals.
-
-* I found a bug! What do I do?
-
-Please send bug reports by email to nicm@users.sourceforge.net or
-tmux-users@lists.sourceforge.net. Please include as much of the following
-information as possible:
-
-- the version of tmux you are running;
-- the operating system you are using and its version;
-- the terminal emulator you are using and the TERM setting when tmux was
-  started;
-- a description of the problem;
-- if the problem is repeatable, the steps to repeat the problem;
-- for screen corruption issues, a screenshot and the output of "infocmp $TERM"
-  from outside tmux are often very useful.
-
-* Why doesn't tmux do $x?
-
-Please send feature requests by email to nicm@users.sourceforge.net.
-
-* Why do you use the screen terminal description inside tmux? It sucks.
-
-It is already widely available. It is planned to change to something else such
-as xterm-xfree86 at some point, if possible.
-
-* I don't see any colour in my terminal! Help!
-
-On some platforms, common terminal descriptions such as xterm do not include
-colour. screen ignores this, tmux does not. If the terminal emulator in use
-supports colour, use a value for TERM which correctly lists this, such as
-xterm-color.
-
-* tmux freezes my terminal when I attach to a session. I even have to kill -9
-  the shell it was started from to recover!
-
-Some consoles really really don't like attempts to set the window title. Tell
-tmux not to do this by turning off the "set-titles" option (you can do this
-in .tmux.conf):
-
-     set -g set-titles off
-
-If this doesn't fix it, send a bug report.
-
-* Why is C-b the prefix key? How do I change it?
-
-The default key is C-b because the prototype of tmux was originally developed
-inside screen and C-b was chosen not to clash with the screen meta key. It
-also has the advantage of not interfering with the use of C-a for start-of-line
-in emacs and the shell (although it does interfere with previous-character).
-
-Changing is simple: change the "prefix-key" option, and - if required - move
-the binding of the "send-prefix" command from C-b (C-b C-b sends C-b by
-default) to the new key. For example:
-
-	set -g prefix C-a
-	unbind C-b
-	bind C-a send-prefix
-
-* How do I use UTF-8?
-
-When running tmux in a UTF-8 capable terminal, UTF-8 must be turned on in tmux;
-as of release 0.9, tmux attempts to autodetect a UTF-8-capable terminal by
-checking the LC_ALL, LC_CTYPE and LANG environment variables. list-clients may
-be used to check if this is detected correctly; if not, the -u command-line
-flag may be specified when creating or attaching a client to a tmux session:
-
-	$ tmux -u new
-
-Since the 1.0 release, tmux will turn on UTF-8 related options automatically
-(ie status-utf8, and utf8) if the above conditions are met.
-
-* How do I use a 256 colour terminal?
-
-Provided the underlying terminal supports 256 colours, it is usually sufficient
-to add the following to ~/.tmux.conf:
-
-	set -g default-terminal "screen-256color"
-
-Note that some platforms do not support "screen-256color" ("infocmp
-screen-256color" will return an error) - in this case see the next entry in
-this FAQ.
-
-tmux attempts to detect a 256 colour terminal both by looking at the colors
-terminfo entry and by looking for the string "256col" in the TERM environment
-variable.
-
-If both these methods fail, the -2 flag may be passed to tmux when attaching
-to a session to indicate the terminal supports 256 colours.
-
-* vim or $otherprogram doesn't display 256 colours. What's up?
-
-Some programs attempt to detect the number of colours a terminal is capable of
-by checking the colors terminfo or Co termcap entry. However, this is not
-reliable, and in any case is missing from the "screen" terminal description
-used inside tmux.
-
-There are two options (aside from using "screen-256color") to allow programs to
-recognise they are running on a 256-colour terminal inside tmux:
-
-- Manually force the application to use 256 colours always or if TERM is set to
-  screen. For vim, you can do this by overriding the t_Co option, see
-  http://vim.wikia.com/wiki/256_colors_in_vim.
-- Creating a custom terminfo file that includes colors#256 in ~/.terminfo and
-  using it instead. These may be compiled with tic(1).
-
-* How do I make Ctrl-PgUp and Ctrl-PgDn work in vim?
-
-tmux supports passing through ctrl (and where supported by the client terminal,
-alt and shift) modifiers to function keys using xterm(1)-style key sequences.
-This may be enabled per window, or globally with the tmux command:
-
-	setw -g xterm-keys on
-
-Because the TERM variable inside tmux must be set to "screen", vim will not
-automatically detect these keys are available; however, the appropriate key
-sequences can be overridden in .vimrc using the following:
-
-	if &term == "screen"
-	set t_kN=^[[6;*~
-	set t_kP=^[[5;*~
-	endif
-
-And similarly for any other keys for which modifiers are desired.
-
-Please note that the "xterm-keys" setting may affect other programs, in the
-same way as running them in a standard xterm; for example most shells do not
-expect to receive xterm(1)-style key sequences so this setting may prevent keys
-such as ctrl-left and ctrl-right working correctly. tmux also passes through
-the ctrl (bit 5 set, for example ^[[5~ to ^[[5^) modifier in non-xterm(1) mode;
-it may be possible to configure vim to accept these, an example of how to do so
-would be welcome.
-
-vim users may also want to set the "ttyfast" option inside tmux.
-
-* Why doesn't elinks set the window title inside tmux?
-
-There isn't a way to detect if a terminal supports setting the window title, so
-elinks attempts to guess by looking at the environment. Rather than looking for
-TERM=screen, it uses the STY variable to detect if it is running in screen;
-tmux does not use this so the check fails. A workaround is to set STY before
-running elinks.
-
-The following shell function does this, and also clears the window title on
-exit (elinks, for some strange reason, sets it to the value of TERM):
-
-	elinks() {
-        	STY= `which elinks` $*
-	        echo -ne \\033]0\;\\007;
-	}
-
-* What is the proper way to escape characters with #(command)?
-
-When using the #(command) construction to include the output from a command in
-the status line, the command will be parsed twice. First, when it's read by the
-configuration file or the command-prompt parser, and second when the status
-line is being drawn and the command is passed to the shell. For example, to
-echo the string "(test)" to the status line, either single or double quotes
-could be used:
-
-	set -g status-right "#(echo \\\\(test\\\\))"
-	set -g status-right '#(echo \\\(test\\\))'
-
-In both cases, the status-right option will be set to the string "#(echo
-\\(test\\))" and the command executed will be "echo \(test\)".
-
-* tmux uses too much CPU. What do I do?
-
-Automatic window renaming may use a lot of CPU, particularly on slow computers:
-if this is a problem, turn it off with "setw -g automatic-rename off". If this
-doesn't fix it, please report the problem.
-
-* I use PuTTY and my tmux window pane separators are all qqqqqqqqq's! 
-
-PuTTY is using a character set translation that doesn't support ACS line
-drawing. With a Unicode font, try setting PuTTY to use a different translation
-on the Window -> Translation configuration page. For example, change UTF-8 to
-ISO-8859-1 or CP437. It may also be necessary to adjust the way PuTTY treats
-line drawing characters in the lower part of the same configuration page.
-
-* What is the best way to display the load average? Why no #L?
-
-It isn't possible to get the load average portably in code and it is preferable
-not to add portability goop. The following works on at least Linux, *BSD and OS
-X:
-
-uptime|awk '{split(substr($0, index($0, "load")), a, ":"); print a[2]}'
-
-* How do I attach the same session to multiple clients but with a different
-  current window, like screen -x?
-
-One or more of the windows can be linked into multiple sessions manually with
-link-window, or a grouped session with all the windows can be created with
-new-session -t.
-
-* Ctrl and arrow keys doesn't work in putty! What do I do?
-
-putty inverts the sense of the cursor key mode on ctrl, which is a bit hard for
-tmux to detect properly. To get ctrl keys right, change the terminfo settings
-so kUP5 (Ctrl-Up etc) are the adjusted versions, and disable smkx/rmkx so tmux
-doesn't change the mode. For example with this line in .tmux.conf (assuming you
-have TERM set to xterm):
-
-set -g terminal-overrides "xterm*:kLFT5=\eOD:kRIT5=\eOC:kUP5=\eOA:kDN5=\eOB:smkx@:rmkx@"
-
-Note that this will only work in tmux 1.2 and above.
-
-* How can I blank the tmux window?
-
-GNU screen has a feature whereby it will blank the screen after a period of
-inactivity. To do the same thing in tmux, use the lock-command setting, for
-example (with GNU bash):
-
-set -g lock-command 'tput civis && read -s -n1'
-
-This will remove the cursor and tell the shell to quit once a key has been
-pressed. For zsh, use "read -s -k1".
-
-In addition, it's possible to have both blanking and locking (for instance via
-lock(1) or vlock(1)) by using the following:
-
-bind x set lock-command '/usr/bin/vlock' \; lock-client \; set lock-command 'tput civis && read -s -n1'
-
-* vim displays reverse video instead of italics, while less displays italics
-  (or just regular text) instead of reverse. What's wrong?
-
-Screen's terminfo description lacks italics mode and has standout mode in its
-place, but using the same escape sequence that urxvt uses for italics. This
-means applications (like vim) looking for italics will not find it and might
-turn to reverse in its place, while applications (like less) asking for
-standout will end up with italics instead of reverse. To make applications
-aware that tmux supports italics and to use a proper escape sequence for
-standout, you'll need to create a new terminfo file with modified sgr, smso,
-rmso, sitm and ritm entries:
-
-	$ mkdir $HOME/.terminfo/
-	$ screen_terminfo="screen"
-	$ infocmp "$screen_terminfo" | sed \
-	  -e 's/^screen[^|]*|[^,]*,/screen-it|screen with italics support,/' \
-	  -e 's/%?%p1%t;3%/%?%p1%t;7%/' \
-	  -e 's/smso=[^,]*,/smso=\\E[7m,/' \
-	  -e 's/rmso=[^,]*,/rmso=\\E[27m,/' \
-	  -e '$s/$/ sitm=\\E[3m, ritm=\\E[23m,/' > /tmp/screen.terminfo
-	$ tic /tmp/screen.terminfo
-
-And tell tmux to use it in ~/.tmux.conf:
-	
-	set -g default-terminal "screen-it"
-
-If your terminal supports 256 colors, use:
-
-	$ screen_terminfo="screen-256color"
-
-instead of "screen". See the FAQ entry about 256 colors support for more info.
-Also note that tmux will still display reverse video on terminals that do not
-support italics.
-
-If your urxvt cannot display italics at all, make sure you have an italics
-capable font enabled, for example, add to ~/.Xdefaults:
-
-	urxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
-
-* How can I make tmux use my terminal's scrollback buffer?
-
-Normally, tmux enables the terminal's "alternate screen". Most terminals (such
-as xterm) do not save scrollback for the alternate screen. You might prefer
-tmux to use the normal screen, so it uses your terminal's scrollback
-buffer. This way, you can access the scrollback buffer as usual, for example
-using the mouse wheel - although there is no guarantee output inside tmux will
-always (or ever) be added to the scrollback.
-
-You can make tmux use the normal screen by telling it that your terminal does
-not have an alternate screen. Put the following in ~/.tmux.conf:
-
-        set -g terminal-overrides 'xterm*:smcup@:rmcup@'
-
-Adjust if your $TERM does not start with xterm.
-
-tmux will still emulate the alternate screen for applications run under tmux,
-so you don't really lose anything with this setting. The only disadvantage is
-that when you exit tmux, it will not restore whatever was there before you
-started.
-
-* How do I see the default configuration?
-
-Show the default session options by starting a new tmux server with no
-configuration file:
-
-        $ tmux -Lfoo -f/dev/null start\; show -g
-
-Or the default window options:
-
-        $ tmux -Lfoo -f/dev/null start\; show -gw

+====================================

+A lot of the compat/ code in tmux comes from libutil, especially imsg.

-NOTES
-=====

-This file describes rough notes regarding ideas for potential future tmux
-development.  It's not necessarily guaranteed that items in this TODO file
-will ever get implemented.
-
-It is asked therefore, that anyone thinking of undertaking a task in this
-TODO file, email tmux-users@lists.sf.net to discuss the feature.
-
-Thie file is split up between tmux user interface (UI) issues, and terminal
-compatibility issues.
-
-TMUX UI ISSUES
-==============
-
-- implicitly add exec to the commands for new windows (switch to disable it)?
-- bring back detach-session to detach all clients on a session?
-- allow fnmatch for -c, so that you can, eg, detach all clients
-- garbage collect window history (100 lines at a time?) if it hasn't been used
-  in $x time
-- flags to centre screen in window
-- activity/bell should be per-window not per-link? what if it is cur win in
-  session not being watched?
-- should be able to move to a hidden pane and it would be moved into view. pane
-  number in status line/top-right would be cool for this
-- support other mouse modes (highlight etc) and use it in copy mode
-- set-remain-on-exit is a bit of a hack, some way to do it generically?
-- would be nice to be able to use "--" to mark start of command w/ neww etc
-  to avoid quoting
-- make command sequences more usable: don't require space after ;, handle
-  errors better
-- choice and more mode would be better per client than per window?
-- hooks to which commands may be attached, for example: tmux add-hook
-  "new-session" if-shell "[ -e $HOME/.tmux-session.conf ]" source-file
-  $HOME/.tmux-session.conf
-- way to set socket path from config file
-- warts on current naming:
-  	- display-time but message-fg/bg/attr
-	- list-* vs show-*
-	- server-info
-	- up-pane/down-pane/swap-pane -U/swap-pane -D vs next-*/previous-*
-	- split-window -> split-pane??
-- some way to force a screen to use the entire terminal even if it is forced
-  to be smaller by other clients. pan smaller terminal? (like screen F)
-	-- idea of a "view" onto a window, need base x/y offsets for redraw
-- commands should be able to succeed or fail and have || or && for command
-  lists
-- some way to keep a command running continually and just use its last line of
-  output
-- UTF-8 to a non-UTF-8 terminal should not be able to balls up
-  the terminal - www/ruby-addressable; make regress
-- support esc-esc to quit in modes
-- fix ctrl+F1-F4 output. to what?
-- better utf8 support: window names, prompt input, message display
-- option to move copy mode indicator into status line
-- selection behaviour closer to vi in vi mode
-- live update: server started with -U connects to server, requests sessions and
-  windows, receives fds
-- sort out inheriting config from shell on new sessions/windows:
-        should pick up default-path/termios/etc from client if possible,
-	else leave empty/default
-- link panes into multiple windows
-- bells should be passed between sessions with visual-bell etc
-  sequence until its shell exits, to allow them to be used from the config file
-- better session sharing: create-socket command to create socket somewhere (-r
-  flag for readonly)
-- multiline status line (no?)
-- support title stack, both internally and externally
-	http://docs.freebsd.org/cgi/getmsg.cgi?fetch=1149299+0+archive/2010/freebsd-questions/20100207.freebsd-questions
-- some way to pad # stuff with spaces, #!2T maybe
-- a binding to "scroll down and exit at bottom" copy mode
-- some way to pass keystrokes in copy mode through to underlying window. why?
-- last window update time and # replacement for it for display-message
-- find-window across sessions - other ways to make session handling easier?
-- ' and " should be parsed the same (eg "\e" vs '\e') in config and command
-  prompt?
-- command to toggle selection not to move it in copy-mode
-- audit of escape sequence support vs xterm
-- support binding keys to mouse (mouse-select-pane -> mouse-keys or something,
-  mouse click == select-pane -t %%, mouse scroll up == copy-mode)
-- bind commands to key sequences? -- make it so ALL keys go through a table,
-  first an implicit table in which C-b is the only default binding to a
-  command that says "next key from $othertable" and so on. means -n can
-  go away as well
-- monitor, bell etc should monitor /all/ panes in the window not just one
-- a history of commands that can be reversed (reverse member of each command,
-  and a buffer)
-- info() when changing to same window
-- way to add dest for break-pane; maybe some easier way to unbreak-pane
-- case insensitive searching
-- incremental searching in copy mode.
-- configurable borders and empty space filler for when panes < window?
-- mouse-select-pane will screw up with !MODE_MOUSE_STANDARD (it sets the
-  flag on w/o checking the others before calling tty_update_mode)
-- pass shell commands as argv rather than strings, allow them to be specified
-  in commands without quotes
-- named buffers and allow gaps in the stack
-- monitor-activity is broken in several ways with multiple clients
-- monitor-activity should be more powerful (eg set a region)
-- maybe a way to put pane names instead of window names in status line
-- support for borderless panes
-- wait-for command 20130222153957.GY6782@yelena.nicm.ath.cx
-- last-pane across sessions
-- panes should have names like windows
-- command-prompt doesn't work if made read-only. why?
-- option to quote format eg #{session_name:quoted}
-- formats need conditions for >0 (for #P)
-- fetch full command line on !Linux, and add option to strip prefixes
-  such as "sh " "/bin/sh " etc etc
-- synchronize-windows option
-- append to buffer in copy mode
-- way to paste w/o trailing whitespace
-- flag to switch-client to switch all clients
-- history of layouts and undo/redo flags to selectl
-- way to tag a layout as a number/name
-- optimize pane redraws, 20120318184853.GK10965@yelena.nicm.ath.cx
-- support multibyte key strings
-- allow commands to be executed when certain patterns in a screen
-  are clicked on with the mouse
-- flag to make next/previous commands skip a window
-- way to do tmux command/run-shell from mode keys
-- send command to all windows
-- choose-pane command (augment choose-tree to do this?)
-- choose-mode and copy-mode are very similar. Perhaps make choose-mode a subset
-  of copy-mode in that it inherits key-bindings and other traits but not all
-- add -c for new-session like new-window
-- flag to choose-* for sort order (eg sort windows/sessions/clients by last
-  used time) - perhaps using formats (but what about numeric sort)?
-- instead of separate window and session options, just one master options list
-  with each option having a type (window or session), then options on window,
-  on session, and global. for window options we look window->session->global,
-  and for session we look session->global
-- maybe keep last layout + size around and if size reverts just put it back
-- way to set hints/limits about pane size for resizing
-- revamp layouts: they are too complicated, should be more closely integrated,
-  should support hints, layout sets should just be a special case of custom
-  layouts, and we should support panes that are not attached to a cell at
-  all. this could be the time to introduce panelink to replace layout_cell
-- run-shell/if-shell should support formats
-- attach should take a pane and select it as well as attaching
-- attach should have a flag to create session if it doesn't exist. or better
-  new a flag to attach it
-
-TERMINAL ISSUES
-================
-
-- use a better termcap internally instead of screen, perhaps xterm
-- clear window title on exit (see using xterm title stack)
-- get it passing all the vttest tests that don't require resizing the terminal
-- support for bce
-- use screen-256color when started on 256 colour terminal?
-* We need a tmux terminfo entry to document the extensions we are using in
-  upstream terminfo. Must NOT change (only add or remove) anything from
-  TERM=screen so we can fallback!
