+;;
+
+;;; Commentary:
+;;
+;; This package is for creating and managing multiple terminal buffers in Emacs.
+;;
+;; By default, term.el provides a great terminal emulator in Emacs.
+;; But I have some troubles with term-mode:
+;;
+;; 1. term.el just provides commands `term' or `ansi-term'
+;; for creating a terminal buffer.
+;; And there is no special command to create or switch
+;; between multiple terminal buffers quickly.
+;;
+;; 2. By default, the keystrokes of term.el conflict with global-mode keystrokes,
+;; which makes it difficult for the user to integrate term.el with Emacs.
+;;
+;; 3. By default, executing *NIX command “exit” from term-mode,
+;; it will leave an unused buffer.
+;;
+;; 4. term.el won’t quit running sub-process when you kill terminal buffer forcibly.
+;;
+;; 5. Haven’t a dedicated window for debug program.
+;;
+;; And multi-term.el is enhanced with those features.
+;;
+
+;;; Installation:
+;;
+;; Copy multi-term.el to your load-path and add to your ~/.emacs
+;;
+;; (require 'multi-term)
+;;
+;; And setup program that `multi-term' will need:
+;;
+;; (setq multi-term-program "/bin/bash")
+;;
+;; or setup like me "/bin/zsh" ;)
+;;
+;; Below are the commands you can use:
+;;
+;; `multi-term' Create a new term buffer.
+;; `multi-term-next' Switch to next term buffer.
+;; `multi-term-prev' Switch to previous term buffer.
+;; `multi-term-dedicated-open' Open dedicated term window.
+;; `multi-term-dedicated-close' Close dedicated term window.
+;; `multi-term-dedicated-toggle' Toggle dedicated term window.
+;; `multi-term-dedicated-select' Select dedicated term window.
+;;
+;; Tips:
+;;
+;; You can type `C-u' before command `multi-term' or `multi-term-dedicated-open'
+;; then will prompt you shell name for creating terminal buffer.
+;;
+
+;;; Customize:
+;;
+;; `multi-term-program' default is nil, so when creating new term buffer,
+;; send environment variable of `SHELL' (`ESHELL', `/bin/sh') to `make-term'.
+;;
+;; And you can set it to your liking, like me: ;-)
+;;
+;; (setq multi-term-program "/bin/zsh")
+;;
+;; `multi-term-default-dir' default is `~/', only use when current buffer
+;; is not in a real directory.
+;;
+;; `multi-term-buffer-name' is the name of term buffer.
+;;
+;; `multi-term-scroll-show-maximum-output' controls how interpreter
+;; output causes window to scroll.
+;;
+;; `multi-term-scroll-to-bottom-on-output' controls whether interpreter
+;; output causes window to scroll.
+;;
+;; `multi-term-switch-after-close' try to switch other `multi-term' buffer
+;; after close current one.
+;; If you don't like this feature just set it with nil.
+;;
+;; `term-unbind-key-list' is a key list to unbind some keystroke.
+;;
+;; `term-bind-key-alist' is a key alist that binds some keystroke.
+;; If you don't like default, modify it.
+;;
+;; `multi-term-dedicated-window-height' the height of a dedicated term window.
+;;
+;; `multi-term-dedicated-max-window-height' the max height limit that dedicated
+;; window is allowed.
+;;
+;; `multi-term-dedicated-skip-other-window-p' whether skip dedicated term
+;; window when use command `other-window' to cycle windows order.
+;;
+;; All of the above can be customize by:
+;; M-x customize-group RET multi-term RET
+;;
+
+;;; Change log:
+;;
+;; 2009/07/04
+;; * Add new option `multi-term-dedicated-select-after-open-p'.
+;;
+;; 2009/06/29
+;; * Fix regexp bug.
+;;
+;; 2009/04/21
+;; * Fix a bug that bring at `2009/03/28':
+;; It will kill sub-process in other multi-term buffer
+;; when we kill current multi-term buffer.
+;;
+;; 2009/03/29
+;; * Add new command `term-send-reverse-search-history'.
+;;
+;; 2009/03/28
+;; * Add new option `multi-term-switch-after-close'.

+;; * Fix doc.
+;;
+;; 2009/01/29
+;; * Use `term-quit-subjob' instead `term-interrupt-subjob'.
+;; * Fix doc.
+;;
+;; 2009/01/13
+;; * Rewrite advice for `pop-to-buffer' to avoid `pop-to-buffer' not effect
+;; when have many dedicated window in current frame.
+;; * Rewrite advice for `delete-other-windows' to avoid use common variable
+;; `delete-protected-window-list' and use `window-dedicated-p' instead.
+;; Remove variable `delete-protected-window-list' and function
+;; `multi-term-dedicated-match-protected-window-p'.
+;;
+;; 2009/01/06
+;; * Improve document.
+;;
+;; 2008/12/29
+;; * Remove option `multi-term-current-window-height' and
+;; function `multi-term-current-directory'.
+;; * Add some functions to make get dedicated term buffer,
+;; those functions is beginning with `multi-term-dedicated-'.
+;; * Modified advice `delete-window', make command `delete-window'
+;; and delete dedicated window, but will remember window height
+;; before deleted.
+;; * Don't remember dedicated window height if larger than max value.
+;; * Fix some bug with `delete-other-windows' and window configuration.
+;; And this bug exists with another extension `sr-speedbar'.
+;; * Add new variable `delete-protected-window-list' for protected
+;; special window that won't be deleted.
+;; This variable is common for any extension that use dedicated
+;; window.
+;; * Fix doc.
+;;
+;; 2008/12/21
+;; * Default bind `C-m' with `term-send-input'.
+;;
+;; 2008/12/10
+;; * Improve customize interface.
+;; * Setup customize automatically, don't need to user setup it up.
+;; * Add option `multi-term-try-create'.
+;; * Make function `multi-term-switch' accept offset argument.
+;; * Fix doc.
+;;
+;; 2008/10/22
+;; * Add variable `multi-term-current-window-height'.
+;; * Add variable `multi-term-buffer-name'.
+;; * Add variable `term-unbind-key-list'.
+;; * Add variable `term-rebind-key-alist'.
+;; * Move key setup and some extension from `term-extension.el'.
+;; * Create new function `multi-term-keystroke-setup'.
