TODO:

[x] oe.py
	[x] Update .oe and .conf parsers to not strip out all the tabs in our 
	    python function vars..

[ ] oebuild
	[ ] Use oe.digraph for handling intertask dependency
	[ ] Split task execution from function execution
	[ ] Revamp the way in which stamps are implemented
	[ ] Add a means to add a task which depends on another task's
	    execution, but not on said task's successful completion.

[.] oemake
	[.] Add oe.conf parsing - abort if OEFILES is not defined
	[.] Add parsing of the .oe's listed in OEFILES
		[ ] Three types of dependency, and any of the three should
		    have a corresponding provides form.  Establish the
		    variable names, and make use of it.  Remember to deal
		    with per package (PACKAGES var) metadata overrides.
	[ ] Handle provides in the digraph...
	[ ] Generic event handling, and addevent declaration for .oe files.

[x] Update patcher tool to make use of our ability to use python functions.
[x] Write package.oeclass implemented w/ a python function/task
[x] Write src.rpm builder .oeclass
[ ] Write ipkg.oeclass which inherits package.oeclass to produce an ipk from
    our metadata.
[ ] Once we have the per package deployment code, write a staging oeclass
    that lets you use the FILES blocks for our deployment packages to do the
    installs into the appropriate staging areas, to save time writing do_stage
    functions.
[.] Finish up extensibility bits for the core oe code, and merge some of the
    class implementations into something sane.
[ ] Assuming cworth has the base ipkg libs rearchitected, start work on oemake.
    If he hasnt, start rearchitecting ipkg.
