;; Commentary:
;;
;; This library implements a TaskJuggler exporter for org-mode.
;; TaskJuggler uses a text format to define projects, tasks and
;; resources, so it is a natural fit for org-mode. It can produce all
;; sorts of reports for tasks or resources in either HTML, CSV or PDF.
;; The current version of TaskJuggler requires KDE but the next
;; version is implemented in Ruby and should therefore run on any
;; platform.
;;
;; The exporter is a bit different from other exporters, such as the
;; HTML and LaTeX exporters for example, in that it does not export
;; all the nodes of a document or strictly follow the order of the
;; nodes in the document.
;;
;; Instead the TaskJuggler exporter looks for a tree that defines the
;; tasks and a optionally tree that defines the resources for this
;; project. It then creates a TaskJuggler file based on these trees
;; and the attributes defined in all the nodes.
;;
;; * Installation
;;
;; Put this file into your load-path and the following line into your
;; ~/.emacs:
;;
;; (require 'org-taskjuggler)
;;
;; The interactive functions are similar to those of the HTML and LaTeX
;; exporters:
;;
;; M-x `org-export-as-taskjuggler'
;; M-x `org-export-as-taskjuggler-and-open'
;;
;; * Tasks
;;
;; Let's illustrate the usage with a small example. Create your tasks
;; as you usually do with org-mode. Assign efforts to each task using
;; properties (it's easiest to do this in the column view). You should
;; end up with something similar to the example by Peter Jones in
;; http://www.contextualdevelopment.com/static/artifacts/articles/2008/project-planning/project-planning.org.
;; Now mark the top node of your tasks with a tag named
;; "taskjuggler_project" (or whatever you customized
;; `org-export-taskjuggler-project-tag' to). You are now ready to
;; export the project plan with `org-export-as-taskjuggler-and-open'
;; which will export the project plan and open a Gantt chart in
;; TaskJugglerUI.
;;
;; * Resources
;;
;; Next you can define resources and assign those to work on specific
;; tasks. You can group your resources hierarchically. Tag the top
;; node of the resources with "taskjuggler_resource" (or whatever you
;; customized `org-export-taskjuggler-resource-tag' to). You can
;; optionally assign an identifier (named "resource_id") to the
;; resources (using the standard org properties commands) or you can
;; let the exporter generate identifiers automatically (the exporter
;; picks the first word of the headline as the identifier as long as
;; it is unique, see the documentation of
;; `org-taskjuggler-get-unique-id'). Using that identifier you can
;; then allocate resources to tasks. This is again done with the
;; "allocate" property on the tasks. Do this in column view or when on
;; the task type
;;
;; C-c C-x p allocate RET <resource_id> RET
;;
;; Once the allocations are done you can again export to TaskJuggler
;; and check in the Resource Allocation Graph which person is working
;; on what task at what time.
;;
;; * Export of properties
;;
;; The exporter also takes TODO state information into consideration,
;; i.e. if a task is marked as done it will have the corresponding
;; attribute in TaskJuggler ("complete 100"). Also it will export any
;; property on a task resource or resource node which is known to
;; TaskJuggler, such as limits, vacation, shift, booking, efficiency,
;; journalentry, rate for resources or account, start, note, duration,
;; end, journalentry, milestone, reference, responsible, scheduling,
;; etc for tasks.
;;
;; * Dependencies
;;
;; The exporter will handle dependencies that are defined in the tasks
;; either with the ORDERED attribute (see TODO dependencies in the Org
;; mode manual) or with the BLOCKER attribute (see org-depend.el) or
;; alternatively with a depends attribute. Both the BLOCKER and the
;; depends attribute can be either "previous-sibling" or a reference
;; to an identifier (named "task_id") which is defined for another
;; task in the project. BLOCKER and the depends attribute can define
;; multiple dependencies separated by either space or comma. You can
;; also specify optional attributes on the dependency by simply
;; appending it. The following examples should illustrate this:
;;
;; * Training material
;; :PROPERTIES:
;; :task_id: training_material
;; :ORDERED: t
;; :END:
;; ** Markup Guidelines
;; :PROPERTIES:
;; :Effort: 2d
;; :END:
;; ** Workflow Guidelines
;; :PROPERTIES:
;; :Effort: 2d
;; :END:
;; * Presentation
;; :PROPERTIES:
;; :Effort: 2d
;; :BLOCKER: training_material { gapduration 1d } some_other_task
;; :END:
;;
;;;; * TODO
;; - Use SCHEDULED and DEADLINE information (not just start and end
;; properties).
;; - Look at org-file-properties, org-global-properties and
;; org-global-properties-fixed
;; - What about property inheritance and org-property-inherit-p?
;; - Use TYPE_TODO as an way to assign resources
;; - Make sure multiple dependency definitions (i.e. BLOCKER on
;; previous-sibling and on a specific task_id) in multiple
;; attributes are properly exported.
