;;; Commentary:
;; This is a major mode which can be used to write files for
;; taskjuggler. See http://www.taskjuggler.org for that scheduling
;; software.
;; The version 2.4.1 of taskjuggler shipped with a tiny emacs lisp
;; file called taskjug.el. From this I have taken the indentation
;; function. All the rest was written from scratch, thus the new name
;; of the file: taskjuggler-mode.el
;; So it's kudos to Sean Dague (http://dague.net) for that older
;; version. In his code he praised Scott Andrew Borton for writing a
;; very good tutorial on writing modes.
;;
;; Webpage: http://www.skamphausen.de/cgi-bin/ska/taskjuggler-mode
;;; FIXMEs
;; * The parser is called too often!
;; * The parser should be able to return several results in one call
;; * Cleanup repetion of task vs resources.
;; * Handling of multi-file documents (includes in the parser)
;; * What about buffer local variants of tasks and resources?
;; * support supplement
;;; TODO
;; * Context-sensitive highlighting, e.g. columns in reports
;; * Ad-Hoc highlighting of things in buffer, e.g. task names,
;; resource names.
;; * Viewing of results, either using TaskjugglerUI or HTML-reports
;;; More Ideas
;; * Sorting of tasks in a context: by name, by priority
;; * Highlighting of priority according to value
;; * Validation of dependencies
