-		The semantics of subarchmap and machinemap changed a bit in 2.0.3 to
-		work better with vapier's CBUILD stuff. I've removed the "monolithic"
-		machinemap from this file and split up its contents amongst the
-		various arch/foo.py files.
-
-		When register() is called on each module in the arch/ dir, it now
-		returns a tuple instead of acting on the subarchmap dict that is
-		passed to it. The tuple contains the values that were previously
-		added to subarchmap as well as a new list of CHOSTs that go along
-		with that arch. This allows us to build machinemap on the fly based
-		on the keys in subarchmap and the values of the 2nd list returned
-		(tmpmachinemap).
-
-		Also, after talking with vapier. I have a slightly better idea of what
-		certain variables are used for and what they should be set to. Neither
-		'buildarch' or 'hostarch' are used directly, so their value doesn't
-		really matter. They are just compared to determine if we are
-		cross-compiling. Because of this, they are just set to the name of the
-		module in arch/ that the subarch is part of to make things simpler.
-		The entire build process is still based off of 'subarch' like it was
-		previously. -agaffney

+Enbedded target, similar to the stage2 target, builds upon a stage2 tarball.

+A stage2 tarball is unpacked, but instead

+		The semantics of subarchmap and machinemap changed a bit in 2.0.3 to
+		work better with vapier's CBUILD stuff. I've removed the "monolithic"
+		machinemap from this file and split up its contents amongst the
+		various arch/foo.py files.
+
+		When register() is called on each module in the arch/ dir, it now
+		returns a tuple instead of acting on the subarchmap dict that is
+		passed to it. The tuple contains the values that were previously
+		added to subarchmap as well as a new list of CHOSTs that go along
+		with that arch. This allows us to build machinemap on the fly based
+		on the keys in subarchmap and the values of the 2nd list returned
+		(tmpmachinemap).
+
+		Also, after talking with vapier. I have a slightly better idea of what
+		certain variables are used for and what they should be set to. Neither
+		'buildarch' or 'hostarch' are used directly, so their value doesn't
+		really matter. They are just compared to determine if we are
+		cross-compiling. Because of this, they are just set to the name of the
+		module in arch/ that the subarch is part of to make things simpler.
