TODO:

[x] oe package
	[x] Update .oe and .conf parsers to not strip out all the tabs in our 
	    python function vars..
	[x] Restructure
	[.] Remove duplicated implementations, and convert everyone to the new
	    data and parse methods.
	[ ] API Sanity Audit.
	[ ] Comment/Docs Audit.
	[x] Allow user supply of .oeclasses to be inherited in every file that
	    gets parsed via the INHERITS variable.
		[x] Add default items to the beginning of INHERITS within
		    the parsers.  In this way, we can automatically pull in
		    base.oeclass for oe files, and build_an_srpm.oeclass for
		    .src.rpm files.

[ ] oebuild and oemake
	[ ] Teach the system to support grabbing OEFILES from upstream
	    using our fetch classes.

[.] oebuild
	[ ] Implement and test check_md5, taking nostamp into account.
	[ ] Add '--undo'/'-u' cmdline opt that calls the 'undo' task
	    for the supplied task.
	[ ] Add '--rebuild'/'-r' cmdline opt that calls the 'undo' task
	    for the entire upward path in the digraph, then builds that task.
	    (same thing done when the md5 changes on an affected var in
	     check_md5)
	[x] Use oe.digraph for handling intertask dependency
	[x] Split task execution from function execution
	[x] Add a means to add a task which depends on another task's
	    execution, but not on said task's successful completion.
	[x] Convert to the new parse and data clases ala oemake.
	[x] Fetch shouldnt use stamps at all.  Hmm, due to the way
	    I implemented override of the check functions, the stamp
	    checker will believe unpack's stamp is always out of date,
	    since its dependency item's stamp doesnt exist.  Need to fix
	    that behavior, then enhance the fetch classes to check for
	    existance.
	[x] move set_automatic_vars into either data or parse
	[x] default flag set for both oe and task metadata
	[x] Fix python function implementation, do it the way I did the
	    code for the event handlers. (needed to fix do_fetch)
	[x] Add clean and mrproper targets to base oeclass.

[.] oemake
	[x] Move OEPATH follow into the individual 'handle' functions,
	    whenever the fn path is relative.  Then kill the init call,
	    as it is really extraneous, given handle does it for you.
	[x] Add oe.conf parsing - abort if OEFILES is not defined
	[x] Add parsing of the .oe's listed in OEFILES
	[x] Handle provides in the digraph...
	[x] Handle dependency on just content/glibc vs content/glibc-2.3.1-r0
	[x] Proper event handling and failout when we encounter an unsatisfied
	    dependency.
	[ ] Check for recursive dependency
	[ ] Deal with multiple provides
	[x] Pull package name, version, and revision based on package metadata,
	    rather than based on the filename in the build tools.  This belongs
	    in the parser code.  In this way, we can more easily facilitate
	    builds of src.rpms, .dsc's, et cetera.
		-aside: pulled set_additional_vars into the new parser code

[.] oemaked
	[x] Autobuilder daemon, monitors files and/or directories
	    For changes, and runs oemake when appropriate.
	[ ] Monitor the stamps for a given .oe file as well, to ensure
	    changes in build state as well as changes to build metadata result
	    in a rebuild.

[ ] packages
	[ ] add cross binutils and binutils
	[ ] add gcc
	[ ] figure out where to put the glibc install into the toolchain dir,
	    which is only needed by gcc pass 2.
	[ ] add qtopia 1.6.1
	[ ] add qt 2.3.6
	[ ] convert packages from OpenZaurus buildroot

[ ] Image creation .oe files and/or external tool

[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
[x] 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.
