+;;
+;; The bs-package contains a main function bs-show for poping up a
+;; buffer in a way similar to `list-buffers' and `electric-buffer-list':
+;; The new buffer offers a Buffer Selection Menu for manipulating
+;; the buffer list and buffers.

+
+;;; Quick Installation und Customization:
+
+;; Use
+;; M-x bs-show
+;; for buffer selection or optional bind a key to main function `bs-show'
+;; (global-set-key "\C-x\C-b" 'bs-show) ;; or another key
+;;
+;; For customization use
+;; M-x bs-customize
+
+
+;;; More Commentary:
+
+;; bs-show will generate a new buffer named *buffer-selection*, which shows
+;; all buffers or a subset of them, and has possibilities for deleting,
+;; saving and selecting buffers. For more details see docstring of
+;; function `bs-mode'. A current configuration describes which buffers appear
+;; in *buffer-selection*. See docstring of variable `bs-configurations' for
+;; more details.
+;;
+;; The package bs combines the advantages of the Emacs functions
+;; `list-buffers' and `electric-buffer-list'.
+;;
+;; Additioal features for Buffer Selection Menu:
+;; - configurable list of buffers (show only files etc.).
+;; - comfortable way to change displayed subset of all buffers.
+;; - show sorted list of buffers.
+;; - cyclic navigation:
+;; - goes to top of buffer list if you are on last line and press down.
+;; - goes to end of buffer list if you are on first line and press up.
+;; - Offer an alternative buffer list by prefix key C-u.
+
+;;; Cycling through buffers
+
+;; This package offers two functions for buffer cycling. If you want to cycle
+;; through buffer list you can use `bs-cycle-next' or `bs-cycle-previous'.
+;; Bind these function to a key like
+;; (global-set-key [(f9)] 'bs-cycle-previous)
+;; (global-set-key [(f10)] 'bs-cycle-next)
+;;
+;; Both functions use a special subset of all buffers for cycling to avoid
+;; to go through internal buffers like *Messages*.
+;;
+;; Cycling through buffers ignores sorting because sorting destroys
+;; the logical buffer list. If buffer list is sorted by size you
+;; won't be able to cycle to the smallest buffer.
+
+;;; Customization:
+
+;; There is a customization group called `bs' in group `convenience'.
+;; Start customization by M-x bs-customize
+;;
+;; Buffer list
+;; -----------
+;; You can define your own configurations by extending variable
+;; `bs-configurations' (see docstring for details).
+;;
+;; `bs-default-configuration' contains the name of default configuration.
+;; The default value is "files" which means to show only files.
+;;
+;; If you always want to see all buffers, customize variable
+;; `bs-default-configuration' in customization group `bs'.
+;;
+;; Configure sorting
+;; -----------------
+;; You can define functions for sorting the buffer list.
+;; When selecting buffers, you can step through available sorting
+;; methods with key 'S'.
+;; To define a new way of sorting, customize variable `bs-sort-functions'.
+;;
+;; There are four basic functions for sorting:
+;; by buffer name, by mode, by size, or by filename
+;;
+;; Configure buffer cycling
+;; ------------------------
+;; When cycling through buffer list the functions for cycling will use
+;; the current configuration of bs to calculate the buffer list.
+;; If you want to use a different configuration for cycling you have to set
+;; the variable `bs-cycle-configuration-name'. You can customize this variable.
+;;
+;; For example: If you use the configuration called "files-and-scratch" you
+;; can cycle through all file buffers and *scratch* although your current
+;; configuration perhaps is "files" which ignores buffer *scratch*.

+
+(autoload (quote idlwave-mode) "idlwave" "\
+Major mode for editing IDL and WAVE CL .pro files.
+
+The main features of this mode are
+
+1. Indentation and Formatting
+ --------------------------
+ Like other Emacs programming modes, C-j inserts a newline and indents.
+ TAB is used for explicit indentation of the current line.
+
+ To start a continuation line, use \\[idlwave-split-line]. This function can also
+ be used in the middle of a line to split the line at that point.
+ When used inside a long constant string, the string is split at
+ that point with the `+' concatenation operator.
+
+ Comments are indented as follows:
+
+ `;;;' Indentation remains unchanged.
+ `;;' Indent like the surrounding code
+ `;' Indent to a minimum column.
+
+ The indentation of comments starting in column 0 is never changed.
+
+ Use \\[idlwave-fill-paragraph] to refill a paragraph inside a comment. The indentation
+ of the second line of the paragraph relative to the first will be
+ retained. Use \\[idlwave-auto-fill-mode] to toggle auto-fill mode for these comments.
+ When the variable `idlwave-fill-comment-line-only' is nil, code
+ can also be auto-filled and auto-indented (not recommended).
+
+ To convert pre-existing IDL code to your formatting style, mark the
+ entire buffer with \\[mark-whole-buffer] and execute \\[idlwave-expand-region-abbrevs].
+ Then mark the entire buffer again followed by \\[indent-region] (`indent-region').
+
+2. Routine Info
+ ------------
+ IDLWAVE displays information about the calling sequence and the accepted
+ keyword parameters of a procedure or function with \\[idlwave-routine-info].
+ \\[idlwave-find-module] jumps to the source file of a module.
+ These commands know about system routines, all routines in idlwave-mode
+ buffers and (when the idlwave-shell is active) about all modules
+ currently compiled under this shell. Use \\[idlwave-update-routine-info] to update this
+ information, which is also used for completion (see next item).
+
+3. Completion
+ ----------
+ \\[idlwave-complete] completes the names of procedures, functions and
+ keyword parameters. It is context sensitive and figures out what
+ is expected at point (procedure/function/keyword). Lower case
+ strings are completed in lower case, other strings in mixed or
+ upper case.
+
+4. Code Templates and Abbreviations
+ --------------------------------
+ Many Abbreviations are predefined to expand to code fragments and templates.
+ The abbreviations start generally with a `\\`. Some examples
+
+ \\pr PROCEDURE template
+ \\fu FUNCTION template
+ \\c CASE statement template
+ \\f FOR loop template
+ \\r REPEAT Loop template
+ \\w WHILE loop template
+ \\i IF statement template
+ \\elif IF-ELSE statement template
+ \\b BEGIN
+
+ For a full list, use \\[idlwave-list-abbrevs]. Some templates also have
+ direct keybindings - see the list of keybindings below.
+
+ \\[idlwave-doc-header] inserts a documentation header at the beginning of the
+ current program unit (pro, function or main). Change log entries
+ can be added to the current program unit with \\[idlwave-doc-modification].
+
+5. Automatic Case Conversion
+ -------------------------
+ The case of reserved words and some abbrevs is controlled by
+ `idlwave-reserved-word-upcase' and `idlwave-abbrev-change-case'.
+
+6. Automatic END completion
+ ------------------------
+ If the variable `idlwave-expand-generic-end' is non-nil, each END typed
+ will be converted to the specific version, like ENDIF, ENDFOR, etc.
+
+7. Hooks
+ -----
+ Loading idlwave.el runs `idlwave-load-hook'.
+ Turning on `idlwave-mode' runs `idlwave-mode-hook'.
+
+8. Documentation and Customization
+ -------------------------------
+ Info documentation for this package is available. Use \\[idlwave-info]
+ to display (complain to your sysadmin if that does not work).
+ For Postscript and HTML versions of the documentation, check IDLWAVE's
+ homepage at `http://www.strw.leidenuniv.nl/~dominik/Tools/idlwave'.
+ IDLWAVE has customize support - see the group `idlwave'.
+
+9. Keybindings
+ -----------
+ Here is a list of all keybindings of this mode.
+ If some of the key bindings below show with ??, use \\[describe-key]
+ followed by the key sequence to see what the key sequence does.
