+;;; Commentary:
+;;
+;; fringe-helper contains helper functions for fringe bitmaps.
+;;
+;; `fringe-helper-define' allows you to to define fringe bitmaps using a visual
+;; string replesentation.  For example:
+;;
+;; (fringe-helper-define 'test-bitmap '(top repeat)
+;;   "XX......"
+;;   "..XX...."
+;;   "....XX.."
+;;   "......XX")
+;;
+;; You can also generate arguments for `define-fringe-bitmap' yourself, by
+;; using `fringe-helper-convert'.
+;;
+;; fringe-helper also provides a few stock bitmaps.  They are loaded on demand
+;; by `fringe-lib-load' and adapt to the current fringe size to a certain
+;; extend.
+;;
+;; `fringe-helper-insert' inserts a fringe bitmap at point and
+;; `fringe-helper-insert-region' inserts a fringe bitmap along a region.
+;; `fringe-helper-remove' removes both kinds.
+;;
+;;
+;; Here's an example for enhancing `flymake-mode' with fringe bitmaps:
+;;
+;; (require 'fringe-helper)
+;; (require 'flymake)
+;;
+;; (defvar flymake-fringe-overlays nil)
+;; (make-variable-buffer-local 'flymake-fringe-overlays)
+;;
+;; (defadvice flymake-make-overlay (after add-to-fringe first
+;;                                  (beg end tooltip-text face mouse-face)
+;;                                  activate compile)
+;;   (push (fringe-helper-insert-region
+;;          beg end
+;;          (fringe-lib-load (if (eq face 'flymake-errline)
+;;                               fringe-lib-exclamation-mark
+;;                             fringe-lib-question-mark))
+;;          'left-fringe 'font-lock-warning-face)
+;;         flymake-fringe-overlays))
+;;
+;; (defadvice flymake-delete-own-overlays (after remove-from-fringe activate
+;;                                         compile)
+;;   (mapc 'fringe-helper-remove flymake-fringe-overlays)
+;;   (setq flymake-fringe-overlays nil))
+;;
+;;
+;;; Change Log:
+;;
+;; 2008-06-04 (0.1.1)
+;;    Fixed bug where `fringe-helper-remove' missed overlays at the end.
+;;    Fixed `fringe-lib-load' to work when already loaded.
+;;
+;; 2008-04-25 (0.1)
+;;    Initial release.

+;;
+;;
+;;; Commentary:
+;;
+;; This minor mode will add little +/- displays to foldable regions in the
+;; buffer and to folded regions. It is indented to be used in conjunction with
+;; hideshow.el which is a part of GNU Emacs since version 20.
+;;
+;; Currently it works for me but is not tested heavily. Please report any bugs
+;; to the above email address
+;;
+;;; Installation:
+;; Add the following to your .emacs:
+;;
+;; (autoload 'hideshowvis-enable "hideshowvis" "Highlight foldable regions")
+;;
+;; (autoload 'hideshowvis-minor-mode
+;;   "hideshowvis"
+;;   "Will indicate regions foldable with hideshow in the fringe."
+;;   'interactive)
+;;
+;;
+;; (dolist (hook (list 'emacs-lisp-mode-hook
+;;                     'c++-mode-hook))
+;;   (add-hook hook 'hideshowvis-enable))
+;;
+;; If enabling hideshowvis-minor-mode is slow on your machine use M-x,
+;; customize-option, hideshowvis-ignore-same-line and set it to nil. This will
+;; then display - icons for foldable regions of one line, too but is faster
+;;
+;; To enable displaying a + symbol in the fringe for folded regions,
+;; use:
+;;
+;;    (hideshowvis-symbols)
+;;
+;; in your ~/.emacs
+;;
+;; It is not enabled by default because it might interfere with custom
+;; hs-set-up-overlay functions
+;;
+;;; Changelog
+;;
+;; v0.5, 2012-09-11
+;; - Made ELPA compliant and added function `hideshowvis-symbols'
+;;
+;; v0.4, 2012-03-13
+;; - fixed bug causing transpose-words to be broken as well as causing problems
+;;   when auto-fill-mode was enabled
+;;
+;; v0.3, 2010-08-26
+;; - added autoload cookies
+;; - fixed bug causing major mode menu to disappear, among other things
+;;
+;; v0.2, 2009-08-09
+;; - '-' symbol in fringe is clickable
+;; - don't show '-' in fringe if the foldable region ends on the same line
