;;; Commentary:
;;
;; ECB stands for "Emacs Code Browser". While Emacs already has good
;; *editing* support for many modes, its *browsing* support is somewhat
;; lacking. That's where ECB comes in: it displays a number of informational
;; windows that allow for easy source code navigation and overview.
;;
;; The informational windows can contain:
;;
;; - A directory tree,
;; - a list of source files in the current directory,
;; - a list of functions/classes/methods/... in the current file, (ECB uses
;; the Semantic Bovinator, or Imenu, or etags, for getting this list so all
;; languages supported by any of these tools are automatically supported by
;; ECB too)
;; - a history of recently visited files,
;; - the Speedbar and
;; - output from compilation (the "*compilation*" window) and other modes like
;; help, grep etc. or whatever a user defines to be displayed in this
;; window.
;;
;; As an added bonus, ECB makes sure to keep these informational windows visible,
;; even when you use C-x 1 and similar commands.
;;
;; It goes without saying that you can configure the layout, ie which
;; informational windows should be displayed where. ECB comes with a number of
;; ready-made window layouts to choose from.
;;
;; Here is an ascii-screenshot of what ECB offers you:

;;; Installation
;;
;; To use the Emacs code browser add the ECB files to your load path and add the
;; following line to your .emacs file:
;;
;; If you want autoloading ECB after first start:
;;
;; (require 'ecb-autoloads)
;;
;; or if you want loading the complete ECB:
;;
;; (require 'ecb)
;;
;; Optional: You can byte-compile ECB with `ecb-byte-compile' after the
;; ECB-package is loaded
;;; Requirements
;;
;; - Semantic, author-version between >= 1.4
;; (http://cedet.sourceforge.net/semantic.shtml).
;; - Eieio, author-version >= 0.17
;; (http://cedet.sourceforge.net/eieio.shtml).
;; - speedbar, author version >= 0.14beta1
;; (http://cedet.sourceforge.net/speedbar.shtml)
;; - Optional: If Java code is edited the ECB works best when the JDEE package
;; (http://sunsite.auc.dk/jde) is installed.
;;; Activation
;;
;; ECB is either activated and started by calling
;; M-x ecb-activate
;; or
;; via the menu "Tools --> Start Code Browser (ECB)"
;;
;; ECB can also be (de)activated/toggled by M-x ecb-minor-mode.
;;
;; After activating ECB you should call `ecb-show-help' to get a detailed
;; description of what ECB offers to you and how to use ECB.
;;; Availability
;;
;; The latest version of the ECB is available at http://ecb.sourceforge.net
;;; History
;;
;; For the ChangeLog of this file see the CVS-repository. For a complete
;; history of the ECB-package see the file NEWS.

(require 'ecb-upgrade)

Emacs-frame for example, because this should be done before the layout is
drawn because ECB computes the size of the ECB-windows with the current frame
size! If you need a hook-option for the real end of the activating process

IMPORTANT: The difference between this hook and

before the layout is redrawn \(for example after calling `ecb-redraw-layout')

"*Specifies all key-bindings for the ECB minor-mode key-map.
The value is a cons-cell where the car is a common-prefix key for all the
key-bindings. The cdr is a list of key-bindings each of them a list again. A
key-binding has the following form:
'\(<common-prefix-flag> <keysequence> <function>) where
<common-prefix-flag>: If t then the common-prefixkey defined as car of the
value \(see above) is used.
<keysequence>: If the common prefixkey is used then the final key-binding is the
concatenation of the common-prefixkey \(see above) and this
keysequence.
<function>: The function to bind to the key. This can also be a
lambda-expression .
It is highly recommended to use one of the standard keys C-c or C-x as first key
of your common-prefixkey!
You MUST change this option via customize to take effect!
All keysequences must be inserted as a string and must follow the syntax needed
by `read-kbd-macro' or `kbd'. This means you can insert the key in the same
manner \"C-h k\" displays keysequences. Here is the summary of the syntax:
Text is divided into \"words \" separated by whitespace. Except for the words
described below, the characters of each word go directly as characters of the
keysequence. The whitespace that separates words is ignored. Whitespace in the
macro must be written explicitly, as in \"C-c SPC\".
* The special words RET, SPC, TAB, DEL, LFD, ESC, and NUL represent special
control characters. The words must be written in uppercase.
* A word in angle brackets, e.g., <return>, <down>, <left> or <f1>, represents
a function key. \(Note that in the standard configuration, the function
key <return> and the control key RET are synonymous.). You can use angle
brackets on the words RET, SPC, etc., but they are not required there.
* Keys can be written by their ASCII code, using a backslash followed by up
to six octal digits. This is the only way to represent keys with codes
above \377.
* One or more prefixes M- \(meta), C- \(control), S- \(shift), A- \(alt),
H- \(hyper), and s- \(super) may precede a character or key notation. For
function keys, the prefixes may go inside or outside of the brackets:
C-<down> = <C-down>. The prefixes may be written in any order: M-C-x =
C-M-x.
Prefixes are not allowed on multi-key words, e.g., C-abc, except that the
Meta prefix is allowed on a sequence of digits and optional minus sign:
M--123 = M-- M-1 M-2 M-3.
* The `^' notation for control characters also works: ^M = C-m."
