;;; Commentary:
;;
;; Once a language file has been parsed into a TAG, it is often useful
;; then display that tag information in browsers, completion engines, or
;; help routines.  The functions and setup in this file provide ways
;; to reformat a tag into different standard output types.
;;
;; In addition, macros for setting up customizable variables that let
;; the user choose their default format type are also provided.
;;

;;; Code:
(require 'semantic)
(require 'semantic/tag-ls)
(require 'ezimage)

(eval-when-compile (require 'semantic/find))

;;; Tag to text overload functions
;;
;; abbreviations, prototypes, and coloring support.
