-CHANGES FROM 2.0 to 2.1 18 October 2015
-
-Incompatible Changes
-====================
-
-* Mouse-mode has been rewritten.  There's now no longer options for:
-	- mouse-resize-pane
-	- mouse-select-pane
-	- mouse-select-window
-	- mode-mouse
-
-  Instead there is just one option:  'mouse' which turns on mouse support
-  entirely.
-* 'default-terminal' is now a session option.  Furthermore, if this is set
-  to 'screen-*' then emulate what screen does.  If italics are wanted, this
-  can be set to 'tmux' but this is still new and not necessarily supported
-  on all platforms with older ncurses installs.
-* The c0-* options for rate-limiting have been removed.  Instead, a backoff
-  approach is used.
-
-Normal Changes
-==============
-
-* New formats:
-	- session_activity
-	- window_linked
-	- window_activity_format
-	- session_alerts
-	- session_last_attached
-	- client_pid
-	- pid
-* 'copy-selection', 'append-selection', 'start-named-buffer' now understand
-  an '-x' flag to prevent it exiting copying mode.
-* 'select-pane' now understands '-P' to set window/pane background colours.
-* 'renumber-windows' now understands windows which are unlinked.
-* 'bind' now understands multiple key tables.  Allows for key-chaining.
-* 'select-layout' understands '-o' to undo the last layout change.
-* The environment is updated when switching sessions as well as attaching.
-* 'select-pane' now understands '-M' for marking a pane.  This marked pane
-  can then be used with commands which understand src-pane specifiers
-  automatically.
-* If a session/window target is prefixed with '=' then only an exact match
-  is considered.
-* 'move-window' understands '-a'.
-* 'update-environment' understands '-E' when attach-session is used on an
-  already attached client.
-* 'show-environment' understands '-s' to output Bourne-compatible commands.
-* New option: 'history-file' to save/restore command prompt history.
-* Copy mode is exited if the history is cleared whilst in copy-mode.
-* 'copy-mode' learned '-e' to exit copy-mode when scrolling to end.
-
-CHANGES FROM 1.9a to 2.0 6 March 2015
-
-Incompatible Changes
-====================
-
-* The choose-list command has been removed.
-* 'terminal-overrides' is now a server option, not a session option.
-* 'message-limit' is now a server option, not a session option.
-* 'monitor-content' option has been removed.
-* 'pane_start_path' option has been removed.
-* The "info" mechanism which used to (for some commands) provide feedback
-  has been removed, and like other commands, they now produce nothing on
-  success.
-
-Normal Changes
-==============
-
-* tmux can now write an entry to utmp if the library 'utempter' is present
-  at compile time.
-* set-buffer learned append mode (-a), and a corresponding
-  'append-selection' command has been added to copy-mode.
-* choose-mode now has the following commands which can be bound:
-	- start-of-list
-	- end-of-list
-	- top-line
-	- bottom-line
-
-* choose-buffer now understands UTF-8.
-* Pane navigation has changed:
-	- The old way of always using the top or left if the choice is ambiguous.
-	- The new way of remembering the last used pane is annoying if the
-	  layout is balanced and the leftmost is obvious to the user (because
-	  clearly if we go right from the top-left in a tiled set of four we want
-	  to end up in top-right, even if we were last using the bottom-right).
-
-      So instead, use a combination of both: if there is only one possible
-      pane alongside the current pane, move to it, otherwise choose the most
-      recently used of the choice.
-* 'set-buffer' can now be told to give names to buffers.
-* The 'new-session', 'new-window', 'split-window', and 'respawn-pane' commands
-  now understand multiple arguments and handle quoting problems correctly.
-* 'capture-pane' understands '-S-' to mean the start of the pane, and '-E-' to
-  mean the end of the pane.
-* Support for function keys beyond F12 has changed.  The following explains:
-	- F13-F24 are S-F1 to S-F12
-	- F25-F36 are C-F1 to C-F12
-	- F37-F48 are C-S-F1 to C-S-F12
-	- F49-F60 are M-F1 to M-F12
-	- F61-F63 are M-S-F1 to M-S-F3
-
- Therefore, F13 becomes a binding of S-F1, etc.
-* Support using pane id as part of session or window specifier (so % means
-  session-of-%1 or window-of-%1) and window id as part of session
-  (so @1 means session-of-@1).
-* 'copy-pipe' command now understands formats via -F
-* 'if-shell'  command now understands formats via -F
-* 'split-window' and 'join-window' understand -b to create the pane to the left
-  or above the target pane.
-
-CHANGES FROM 1.9 to 1.9a 22 February 2014
-
-NOTE:  This is a bug-fix release to address some important bugs which just
-missed the 1.9 deadline, but were found afterwards.
-
-Normal Changes
-==============
-
-* Fix crash due to uninitialized lastwp member of layout_cell
-* Fix -fg/-bg/-style with 256 colour terminals.  
-
-CHANGES FROM 1.8 to 1.9, 20 February 2014
-
-NOTE:  This release has bumped the tmux protocol version.  It is therefore
-advised that the prior tmux server is restarted when this version of tmux is
-installed, to avoid protocol mismatch errors for newer clients trying to
-talk to an older running tmux server.
-
-Incompatible Changes
-====================
-
-* 88 colour support has been removed.
-* 'default-path' has been removed.  The new-window command accepts '-c' to
-  cater for this.  The previous value of "." can be replaced with: 'neww -c
-  $PWD', the previous value of '' which meant current path of the pane can
-  be specified as:  'neww -c "#{pane_current_path}"'
-
-Deprecated Changes
-==================
-
-* The single format specifiers:  #A -> #Z (where defined) have been
-  deprecated and replaced with longer-named equivalents, as listed in the
-  FORMATS section of the tmux manpage.
-* The various foo-{fg,bg,attr} commands have been deprecated and replaced
-  with equivalent foo-style option instead.  Currently this is still
-  backwards-compatible, but will be removed over time.
-
-Normal Changes
-==============
-
-* A new environment variable TMUX_TMPDIR is now honoured, allowing the
-  socket directory to be set outside of TMPDIR (/tmp/ if not set).
-* If -s not given to swap-pane the current pane is assumed.
-* A #{pane_syncronized} format specifier has been added to be a conditional
-  format if a pane is in a syncronised mode (c.f. syncronize-panes)
-* Tmux now runs under Cygwin natively.
-* Formats can now be nested within each other and expanded accordingly.
-* Added 'automatic-rename-format' option to allow the automatic rename
-  mechanism to use something other than the default of
-  #{pane_current_command}.
-* new-session learnt '-c' to specify the starting directory for that session
-  and all subsequent windows therein.
-* The session name is now shown in the message printed to the terminal when
-  a session is detached.
-* Lots more format specifiers have been added.
-* Server race conditions have been fixed; in particular commands are not run
-  until after the configuration file is read completely.
-* Case insensitive searching in tmux's copy-mode is now possible.
-* attach-session and switch-client learnt the '-t' option to accept a window
-  and/or a pane to use.
-* Copy-mode is only exited if no selection is in progress.
-* Paste key in copy-mode is now possible to enter text from the clipboard.
-* status-interval set to '0' now works as intended.
-* tmux now supports 256 colours running under fbterm.
-* Many bug fixes!
-
-CHANGES FROM 1.7 to 1.8, 26 March 2013
-
-Incompatible Changes
-====================
-
-* layout redo/undo has been removed.
-
-Normal Changes
-==============

-* Session choosing fixed to work with unattached sessions.
-* New window options window-status-last-{attr,bg,fg} to denote the last
-  window which was active.
-* Scrolling in copy-mode now scrolls the region without moving the mouse
-  cursor.
-* run-shell learnt '-t' to specify the pane to use when displaying output.
-* Support for middle-click pasting.
-* choose-tree learns '-u' to start uncollapsed.
-* select-window learnt '-T' to toggle to the last window if it's already
-  current.
-* New session option 'assume-paste-time' for pasting text versus key-binding
-  actions.
-* choose-* commands now work outside of an attached client.
-* Aliases are now shown for list-commands command.
-* Status learns about formats.
-* Free-form options can be set with set-option if prepended with an '@'
-  sign.
-* capture-pane learnt '-p' to send to stdout, and '-e' for capturing escape
-  sequences, and '-a' to capture the alternate screen, and '-P' to dump
-  pending output.
-* Many new formats added (client_session, client_last_session, etc.)
-* Control mode, which is a way for a client to send tmux commands.
-  Currently more useful to users of iterm2.
-* resize-pane learnt '-x' and '-y' for absolute pane sizing.
-* Config file loading now reports errors from all files which are loaded via
-  the 'source-file' command.
-* 'copy-pipe' mode command to copy selection and pipe the selection to a
-  command.
-* Panes can now emit focus notifications for certain applications
-  which use those.
-* run-shell and if-shell now accept formats.
-* resize-pane learnt '-Z' for zooming a pane temporarily.
-* new-session learnt '-A' to make it behave like attach-session.
-* set-option learnt '-o' to prevent setting an option which is already set.
-* capture-pane and show-options learns '-q' to silence errors.

-* Resizing panes will now reflow the text inside them.
-* Lots and lots of bug fixes, fixing memory-leaks, etc.
-* Various manpage improvements.
-
-CHANGES FROM 1.6 to 1.7, 13 October 2012
-
-* tmux configuration files now support line-continuation with a "\" at the
-  end of a line.
-* New option status-position to move the status line to the top or bottom of
-  the screen.
-* Enforce history-limit option when clearing the screen.
-* Give each window a unique id, like panes but prefixed with @.
-* Add pane id to each pane in layout description (while still accepting
-  the old form).
-* Provide defined ways to set the various default-path possibilities: ~
-  for home directory, . for server start directory, - for session start
-  directory and empty for the pane's working directory (the default). All
-  can also be used as part of a relative path (eg -/foo). Also provide -c
-  flags to neww and splitw to override default-path setting.
-* Add -l flag to send-keys to send input literally (without translating
-  key names).
-* Allow a single option to be specified to show-options to show just that
-  option.
-* New command "move-pane" (like join-pane but allows the same window).

-* copy mode learns "wrap-search" option.
-* Add a simple form of output rate limiting by counting the number of
-  certain C0 sequences (linefeeds, backspaces, carriage returns) and if it
-  exceeds a threshold (current default 250/millisecond), start to redraw
-  the pane every 100 milliseconds instead of making each change as it
-  comes. Two configuration options - c0-change-trigger and
-  c0-change-interval.
-* find-window learns new flags:  "-C", "-N", "-T" to match against either or
-  all of a window's content, name, or title.  Defaults to all three options
-  if none specified.
-* find-window automatically selects the appropriate pane for the found
-  matches.
-* show-environment can now accept one option to show that environment value.
-* Exit mouse mode when end-of-screen reached when scrolling with the mouse
-  wheel.
-* select-layout learns -u and -U for layout history stacks.
-* kill-window, detach-client, kill-session all  learn "-a" option for
-  killing all but the current thing specified.
-* move-window learns "-r" option to renumber window sequentially in a
-  session.
-* New session option "renumber-windows" to automatically renumber windows in
-  a session when a window is closed.  (see "move-window -r").
-* Only enter copy-mode on scroll up.
-* choose-* and list-* commands all use "-F" for format specifiers.
-* When spawning external commands, the value from the "default-shell" option
-  is now used, rather than assuming /bin/sh.
-* New choose-tree command to render window/sessions as a tree for selection.
-* display-message learns new format options.
-* For linked-windows across sessions, all flags for that window are now
-  cleared across sessions.

-* Various manpage improvements.
-
-CHANGES FROM 1.5 TO 1.6, 23 January 2012
-
-* Extend the mode-mouse option to add a third choice which means the mouse
-  does not enter copy mode.
-* Add a -r flag to switch-client to toggle the client read-only flag.
-* Add pane-base-index option.
-* Support \ for line continuation in the configuration file.
-* Framework for more powerful formatting of command output and use it for
-  list-{panes,windows,sessions}. This allows more descriptive replacements
-  (such as #{session_name}) and conditionals.
-* Mark dead panes with some text saying they are dead.
-* Reject $SHELL if it is not a full path.
-* Add -S option to refresh-client to redraw status line.
-* Add an else clause for if-shell.
-* Try to resolve relative paths for loadb and saveb (first, using client
-  working directory, if any, then default-path or session working directory).
-* Support for \e[3J to clear the history and send the corresponding
-  terminfo code (E3) before locking.
-* When in copy mode, make repeat count indicate buffer to replace, if used.
-* Add screen*:XT to terminal-overrides for tmux-in-tmux.
-* Status-line message attributes added.
-* Move word-separators to be a session rather than window option.
-* Change the way the working directory for new processes is discovered. If
-  default-path isn't empty, it is used. Otherwise, if a new window is created
-  from the command-line, the working directory of the client is used. If not,
-  platform specific code is used to retrieve the current working directory
-  of the process in the active pane. If that fails, the directory where the
-  session was created is used, instead.
-* Do not change the current pane if both mouse-select-{pane,window} are
-  enabled.
-* Add \033[s and \033[u to save and restore cursor position.
-* Allow $HOME to be used as default-path.
-* Add CNL and CPL escape sequences.
-* Calculate last position correctly for UTF-8 wide characters.
-* Add an option allow-rename to disable the window rename escape sequence.
-* Attributes for each type of status-line alert (ie bell, content and
-  activity) added. Therefore, remove the superfluous options
-  window-status-alert-{attr,bg,fg}.
-* Add a -R flag to send-keys to reset the terminal.
-* Add strings to allow the aixterm bright colours to be used when
-  configuring colours.
-* Drop the ability to have a list of keys in the prefix in favour of two
-  separate options, prefix and prefix2.
-* Flag -2 added to send-prefix to send the secondary prefix key.
-* Show pane size in top right of display panes mode.
-* Some memory leaks plugged.
-* More command-prompt editing improvements.
-* Various manpage improvements.
-* More Vi mode improvements.
-
-CHANGES FROM 1.4 TO 1.5, 09 July 2011
-
-* Support xterm mouse modes 1002 and 1003.
-* Change from a per-session stack of buffers to one global stack. This renders
-  copy-buffer useless and makes buffer-limit now a server option.
-* Fix most-recently-used choice by avoiding reset the activity timer for
-  unattached sessions every second.
-* Add a -P option to new-window and split-window to print the new window or
-  pane index in target form (useful to pass it into other commands).
-* Handle a # at the end of a replacement string (such as status-left)
-  correctly.
-* Support for UTF-8 mouse input (\033[1005h) which was added in xterm 262.
-  If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all
-  UTF-8 terminals. The option defaults to on if LANG etc are set in the same
-  manner as the utf8 option.
-* Support for HP-UX.
-* Accept colours of the hex form #ffffff and translate to the nearest from the
-  xterm(1) 256-colour set.
-* Clear the non-blocking IO flag (O_NONBLOCK) on the stdio file descriptors
-  before closing them (fixes things like "tmux ls && cat").
-* Use TMPDIR if set.
-* Fix next and previous session functions to actually work.
-* Support -x and -y for new-session to specify the initial size of the window
-  if created detached with -d.
-* Make bind-key accept characters with the top-bit-set and print them as octal.
-* Set $TMUX without the session when background jobs are run.
-* Simplify the way jobs work and drop the persist type, so all jobs are
-  fire-and-forget.
-* Accept tcgetattr/tcsetattr(3) failure, fixes problems with fatal() if the
-  terminal disappears while locked.
-* Add a -P option to detach to HUP the client's parent process (usually causing
-  it to exit as well).
-* Support passing through escape sequences to the underlying terminal by using
-  DCS with a "tmux;" prefix.
-* Prevent tiled producing a corrupt layout when only one column is needed.
-* Give each pane created in a tmux server a unique id (starting from 0), put it
-  in the TMUX_PANE environment variable and accept it as a target.
-* Allow a start and end line to be specified for capture-pane which may be
-  negative to capture part of the history.
-* Add -a and -s options to lsp to list all panes in the server or session
-  respectively. Likewise add -s to lsw.
-* Change -t on display-message to be target-pane for the #[A-Z] replacements
-  and add -c as target-client.
-* The attach-session command now prefers the most recently used unattached
-  session.
-* Add -s option to detach-client to detach all clients attached to a session.
-* Add -t to list-clients.
-* Change window with mouse wheel over status line if mouse-select-window is on.
-* When mode-mouse is on, automatically enter copy mode when the mouse is
-  dragged or the mouse wheel is used. Also exit copy mode when the mouse wheel
-  is scrolled off the bottom.
-* Provide #h character pair for short hostname (no domain).
-* Don't use strnvis(3) for the title as it breaks UTF-8.
-* Use the tsl and fsl terminfo(5) capabilities to update terminal title and
-  automatically fill them in on terminals with the XT capability (which means
-  their title setting is xterm-compatible).
-* Add a new option, mouse-resize-pane. When on, panes may be resized by
-  dragging their borders.
-* Fix crash by resetting last pane on {break,swap}-pane across windows.
-* Add three new copy-mode commands - select-line, copy-line, copy-end-of-line.
-* Support setting the xterm clipboard when copying from copy mode using the
-  xterm escape sequence for the purpose (if xterm is configured to allow it).
-* Support xterm(1) cursor colour change sequences through terminfo(5) Cc
-  (set) and Cr (reset) extensions.
-* Support DECSCUSR sequence to set the cursor style with two new terminfo(5)
-  extensions, Cs and Csr.
-* Make the command-prompt custom prompts recognize the status-left option
-  character pairs.
-* Add a respawn-pane command.
-* Add a couple of extra xterm-style keys that gnome terminal provides.
-* Allow the initial context on prompts to be set with the new -I option to
-  command-prompt. Include the current window and session name in the prompt
-  when renaming and add a new key binding ($) for rename session.
-* Option bell-on-alert added to trigger the terminal bell when there is an
-  alert.
-* Change the list-keys format so that it shows the keys using actual tmux
-  commands which should be able to be directly copied into the config file.
-* Show full targets for lsp/lsw -a.
-* Make confirm-before prompt customizable with -p option like command-prompt
-  and add the character pairs #W and #P to the default kill-{pane,window}
-  prompts.
-* Avoid sending data to suspended/locked clients.
-* Small memory leaks in error paths plugged.
-* Vi mode improvements.

-To enable italics, create a new terminfo entry called "tmux" (some platforms

-* How can I make tmux use my terminal's scrollback buffer?
+* tmux doesn't start with "daemon failed"
 
-Normally, tmux enables the terminal's "alternate screen". Most terminals (such
+tmux shows something similar to this when started:
-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
+    fatal: server_start: daemon failed: No such file or directory
-not have an alternate screen. Put the following in ~/.tmux.conf:
+    fatal: main_dispatch: imsg_read failed
 
-        set -ga terminal-overrides ',xterm*:smcup@:rmcup@'
+A possible reason is that /dev/null is not a character device or is otherwise
+inaccessible.
 
-Adjust if your $TERM does not start with xterm.
+Check with:
 
-tmux will still emulate the alternate screen for applications run under tmux,
+    file /dev/null
-so you don't really lose anything with this setting. The only disadvantage is
+    ls -l /dev/null
-that when you exit tmux, it will not restore whatever was there before you
-started.
 
-* How do I see the default configuration?
+If it is not a character device or has incorrect permissions, it can typically
+be recreated with:
 
-Show the default session options by starting a new tmux server with no
+    cd /dev && rm null && ./MAKEDEV null
-configuration file:
-
-        $ tmux -Lfoo -f/dev/null start\; show -g
-
-Or the default window options:
-
-        $ tmux -Lfoo -f/dev/null start\; show -gw
-
-* How do I copy a selection from tmux to the system's clipboard?
-
-When running in xterm(1), tmux can automatically send copied text to the
-clipboard. This is controlled by the set-clipboard option and also needs this
-X resource to be set:
-
-	XTerm*disallowedWindowOps: 20,21,SetXprop
-
-For rxvt-unicode (urxvt), there is an unofficial Perl extension here:
-
-        http://anti.teamidiot.de/static/nei/*/Code/urxvt/
-
-Otherwise a key binding for copy mode using xclip (or xsel) works:
-
-	bind -temacs-copy C-y copy-pipe "xclip -i >/dev/null"
-
-Or for inside and outside copy mode with the prefix key:
-
-        bind C-y run -b "tmux save-buffer - | xclip -i"
-
-On OS X, reattach-to-usernamespace lets pbcopy/pbpaste work:

-* Why do I see dots around a session when I attach to it?
+$Id: FAQ,v 1.41 2010-12-15 23:31:30 nicm Exp $
-
-tmux limits the size of the window to the smallest attached session. If
-it didn't do this then it would be impossible to see the entire window.
-The dots mark the size of the window tmux can display.
-
-To avoid this, detach all other clients when attaching:
-
-	$ tmux attach -d
-
-Or from inside tmux by detaching individual clients with C-b D or all
-using:
-
-	C-b : attach -d

+Welcome to tmux!
+
+tmux is a "terminal multiplexer", it enables a number of terminals (or windows)
+to be accessed and controlled from a single terminal. tmux is intended to be a
+simple, modern, BSD-licensed alternative to programs such as GNU screen.
+
+This release runs on OpenBSD, FreeBSD, NetBSD, Linux and OS X and may still
+run on Solaris and AIX (although they haven't been tested in a while). It is
+usable, although there remain a number of missing features and some remaining
+bugs are expected.
+
+Since the 1.2 release that tmux depends on libevent. Download the stable
+version from:
+
+	http://www.monkey.org/~provos/libevent/
+
+tmux consists of a server part and multiple clients. The server is created when
+required and runs continuously unless killed by the user. Clients access the
+server through a socket in /tmp. Multiple sessions may be created on a single
+server and attached to a number of clients. Each session may then have a number
+of windows and windows may be linked to a number of sessions. Commands are
+available to create, rename and destroy windows and sessions; to attach and
+detach sessions from client terminals; to set configuration options; to split
+windows into several simultaneously displayed panes; and to bind and unbind
+command keys (invoked preceded by a prefix key, by default ctrl-b). Please see
+the tmux(1) man page for further information.
+
+A more extensive, but rough, todo list is included in the TODO file.
+
+tmux also depends on several features of the client terminal (TERM), if these
+are missing it may refuse to run, or not behave correctly.
+
+A Vim syntax file is available in the examples directory. To install it:
+
+- Drop the file in the syntax directory in your runtimepath (such as
+  ~/.vim/syntax/tmux.vim).
+- Make the filetype recognisable by adding the following to filetype.vim
+  in your runtimepath (~/.vim/filetype.vim):
+
+	augroup filetypedetect
+		au BufNewFile,BufRead .tmux.conf*,tmux.conf* setf tmux
+	augroup END
+
+- Switch on syntax highlighting by adding "syntax enable" to your vimrc file.
+
+For debugging, running tmux with -v or -vv will generate server and client log
+files in the current directory.
+
+tmux mailing lists are available; visit:
+
+	https://sourceforge.net/mail/?group_id=200378
+
+Bug reports, feature suggestions and especially code contributions are most
+welcome. Please send by email to:
+

-Welcome to tmux!
-
-tmux is a "terminal multiplexer", it enables a number of terminals (or windows)
-to be accessed and controlled from a single terminal. tmux is intended to be a
-simple, modern, BSD-licensed alternative to programs such as GNU screen.
-
-This release runs on OpenBSD, FreeBSD, NetBSD, Linux, OS X and Solaris.
-
-tmux depends on libevent 2.x. Download it from:
-
-	http://www.monkey.org/~provos/libevent/
-
-To build tmux from a release tarball, do:
-
-	$ ./configure && make
-	$ sudo make install
-
-To get and build the latest from version control:
-
-	$ git clone https://github.com/tmux/tmux.git
-	$ cd tmux
-	$ sh autogen.sh
-	$ ./configure && make
-
-For more information see http://git-scm.com. Patches should be sent by email to
-the mailing list at tmux-users@googlegroups.com.
-
-For documentation on using tmux, see the tmux.1 manpage. It can be viewed from
-the source tree with:
-
-	$ nroff -mdoc tmux.1|less
-
-Some common questions are answered in the FAQ file and a more extensive (but
-slightly out of date) guide is available in the OpenBSD FAQ at
-http://www.openbsd.org/faq/faq7.html#tmux. A rough todo list is in the TODO
-file and some example configurations and a Vim syntax file are in the examples
-directory.
-
-For debugging, running tmux with -v or -vv will generate server and client log
-files in the current directory.
-
-tmux mailing lists are available. For general discussion and bug reports:
-
-	https://groups.google.com/forum/#!forum/tmux-users
-
-And for Git commit emails:
-
-	https://groups.google.com/forum/#!forum/tmux-git
-
-Bug reports, feature suggestions and especially code contributions are most
-welcome. Please send by email to:

SYNCING

@@ -1,176 +0,0 @@
-Preamble
-========
-
-Tmux portable relies on  repositories "tmux" and "tmux-openbsd".
-Here's a description of them:
-
-* "tmux" is the portable version, the one which contains code for other
-  operating systems, and autotools, etc., which isn't found or needed in the
-  OpenBSD base system.
-
-* "tmux-openbsd" is the version of tmux in OpenBSD base system which provides
-  the basis of the portable tmux version.
-
-Note:  The "tmux-openbsd" repository is actually handled by "git cvsimport"
-running at 15 minute intervals, so a commit made to OpenBSD's tmux CVS
-repository will take at least that long to appear in this git repository.
-(It might take longer, depending on the CVS mirror used to import the
-OpenBSD code).
-
-If you've never used git before, git tracks meta-data about the committer
-and the author, as part of a commit, hence:
-
-% git config [--global] user.name "Your name"
-% git config [--global] user.email "you@yourdomain.com"
-
-Note that, if you already have this in the global ~/.gitconfig option, then
-this will be used.  Setting this per-repository would involve not using the
-"--global" flag above.   If you wish to use the same credentials always,
-pass the "--global" option, as shown.
-
-This is a one-off operation once the repository has been cloned, assuming
-this information has ever been set before.
-
-Cloning repositories
-====================
-
-This involves having both tmux and tmux-openbsd cloned, as in:
-
-% cd /some/where/useful
-% git clone https://github.com/tmux/tmux.git
-% git clone https://github.com/ThomasAdam/tmux-openbsd.git
-
-Note that you do not need additional checkouts to manage the sync -- an
-existing clone of either repositories will suffice.  So if you already have
-these checkouts existing, skip that.
-
-Adding in git-remotes
-=====================
-
-Because the portable "tmux" git repository and the "tmux-openbsd"
-repository do not inherently share any history between each other, the
-history has been faked between them.  This "faking of history" is something
-which has to be told to git for the purposes of comparing the "tmux" and
-"tmux-openbsd" repositories for syncing.  To do this, we must reference the
-clone of the "tmux-openbsd" repository from the "tmux" repository, as
-shown by the following command:
-
-% cd /path/to/tmux
-% git remote add obsd-tmux file:///path/to/tmux-openbsd
-
-So that now, the remote "obsd-tmux" can be used to reference branches and
-commits from the "tmux-openbsd" repository, but from the context of the
-portable "tmux" repository, which makes sense because it's the "tmux"
-repository which will have the updates applied to them.
-
-Fetching updates
-================
-
-To ensure the latest commits from "tmux-openbsd" can be found from within
-"tmux", we have to ensure the "master" branch from "tmux-openbsd" is
-up-to-date first, and then reference that update in "tmux", as in:
-
-% cd /path/to/tmux-openbsd
-% git checkout master
-% git pull
-
-Then back in "tmux":
-
-% cd /path/to/tmux
-% git fetch obsd-tmux
-
-Creating the necessary branches
-===============================
-
-Now that "tmux" can see commits and branches from "tmux-openbsd" by way
-of the remote name "obsd-tmux", we can now create the master branch from
-"tmux-openbsd" in the "tmux" repository:
-
-% git checkout -b obsd-master obsd-tmux/master
-
-Adding in the fake history points
-================================= 
-
-To tie both the "master" branch from "tmux" and the "obsd-master"
-branch from "tmux-openbsd" together, the fake history points added to the
-"tmux" repository need to be added.  To do this, we must add an
-additional refspec line, as in:
-
-% cd /path/to/tmux
-% git config --add remote.origin.fetch '+refs/replace/*:refs/replace/*'
-% git fetch origin
-
-Performing the Sync
-===================
-
-Make sure the "master" branch is checked out:
-
-% git checkout master
-
-The following will show commits on OpenBSD not yet synched with "tmux":
-
-% git log master..obsd-master
-
-From there, merge the result in, fixing up any conflicts which might arise.
-
-% git merge obsd-master
-
-Then ensure things look correct by BULDING the result of that sync:
-
-% make clean && ./autogen.sh && ./configure && make
-
-Compare the git merge result with what's on origin/master -- that is, check
-which commits you're about to push:
-
-% git log origin/master..master
-
-And if happy:
-
-% git push origin master
-
-Keeping an eye on libutil in OpenBSD
-====================================
-
-A lot of the compat/ code in tmux comes from libutil, especially imsg.
-Sometimes the API can change, etc., which might cause interesting problems
-trying to run the portable version of tmux.  It's worth checking
-periodically for any changes to libutil in OpenBSD and syncing those files
-to compat/ as and when appropriate.
-
-Release tmux for next version
-=============================
-
-1. Comment the "found_debug=yes" line in configure.ac, since releases
-   don't have debugging enabled, otherwise make(1) aborts when
-   preparing the distribution.
-
-2. Update and commit README and CHANGES.  The former should be checked for
-   anything outdated and updated with a list of things that might break
-   upgrades and the latter should mention all the major changes since
-   the last version.
-
-3. Tag with:
-
-   % git tag -a 2.X
-
-   Where "2.X" is the next version.
-
-   Push the tag out with:
-
-   % git push 2.X
-
-4. Build the tarball with 'make dist'.
-
-5. Check the tarball.  If it's good, go here to select the tag just pushed:
-
-   https://github.com/tmux/tmux/tags
-
-   Click the "Add release notes", upload the tarball and add a link in the
-   description field to the CHANGES file.
-
-7. Clone the tmux.github.io repository, and change the RELEASE version in
-   the Makefile.  Commit it, and run 'make' to replace %%VERSION%%.  Push
-   the result out.
-
-8. Bump version in tmu/tmux.git configure.ac and uncomment "found_debug=yes" to
-   create a debug build by default.

-- better UTF-8 support:
-	* window names and titles
-	* message display
-	* prompt input
-	* multibyte key input
-	* searching in copy mode
-
-- copy/paste improvements:
-	* incremental searching
-	* paste w/o trailing whitespace
-	* command to toggle selection not to move it in copy-mode
-	* regex searching
-	* copy-pipe should have -x as well
-
-- layout stuff
-	* way to tag a layout as a number/name
-	* maybe keep last layout + size around and if size reverts just put it
-	  back
-	* 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
-	* way to set hints/limits about pane size for resizing
-	* panning over window (window larger than visible)
-	* a mode where one application can cross two panes (ie x|y, width =
-	  COLUMNS/2 but height = ROWS * 2)
-	* general key to space cells out evenly (horiz or vert) within their
-	  parent cell (could replace even-vert/even-horiz layouts)
-	* separate active panes for different clients
-
-- terminfo bits
-	* use a better termcap internally instead of screen, perhaps xterm
-	* use screen-256color when started on 256 colour terminal?
-
-- code cleanup
-	* 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
-	* the way pane, window, session destroy is handled is too complicated
-	  and the distinction between session.c, window.c and server-fn.c
-	  functions is not clear. could we just have kill_pane(),
-	  kill_window(), unlink_window(), kill_session() that fix up all data
-	  structures (flagging sessions as dead) and return a value to say
-	  whether clients need to be checked for dead sessions? sort of like
-	  session_detach now but more so. or some other scheme to make it
-	  simpler and clearer? also would be nice to remove/rename server-fn.c
-	* more readable way to work out the various things commands need to
-	  know about the client, notably:
-		- is this the config file? (cmdq->c == NULL)
-		- is this a command client? (cmdq->c != NULL &&
-		  cmdq->c->session == NULL)
-		- is this a control client?
-		- can i do stdin or stdout to this client?
-	  or even guarantee that cmdq->c != NULL and provide a better way to
-	  tell when in the config file - then we use cmdq->c if we need a
-	  client w/o a session else cmd_current_client
-	* optimize pane redraws, 20120318184853.GK10965@yelena.nicm.ath.cx
-
-- miscellaneous
-	* way to keep a job running just read its last line of output for #()
-	* link panes into multiple windows
-	* live update: server started with -U connects to server, requests
-	  sessions and windows, receives file descriptors
-	* there are inconsistencies in what we get from old shell and what
-	  comes from config for new sessions and windows. likewise, panes and
-	  jobs and run-shell and lock command all start with slightly different
-	  environments
-	* multiline status line?
-	* customizable command aliases
-	* automatic pane logging
-	* BCE? We are halfway there (output side is done for pane backgrounds),
-	  just need to change how screen/grid handles erase
