+spatches are the semantic patches
+tmp is just tmp
+inputs are copied from $LINUX
+per-file-changes contain input files that have specific transforms
+final contains the final form of the file, with 'global' changes applied (e.g. kzalloc -> calloc)
+
+transform copies files from $LINUX and then transforms them for use by stand-alone program/coreboot
+
+The Makefile is simple; this runs 'fast enough' that a complicated Makefile is not worth it.
+
+There's still some duct tape here but it's getting there.

+#!/bin/bash
+# This script has been honed over quite a few iterations. The trick is to make
+# it easy for you to see what transformations occur
+# without burying you in files.
+# Also, coccinelle is not perfect, so we have to help her at times. As she
+# gets smarter, we can shrink thigns we do in here.
+# So we get input files, then do per-file changes, then do all-file changes
+# I've deliberately made this script simple. Please don't decide it needs to
+# be automagic. Just let it work in its simple way. Also, if you change even
+# one simple thing, ALWAYS rerun this script do make sure you did not make a
+# global test. NEVER test one little thing in isolation. That way
+# lies madness.
+# The only thing you need to set is
+# export LINUX=/path/to/your/linux/tree.
+# Order in which we do things.
+# 1. Get source files into inputs.
+# 2. cp them to per-file-changes
+#    Note that we even copy ones that might not currently need per-file
+#    changes. Because they may in future and it keeps the script simple.
+#    We tried both ways and like this best.
+# 3. run 'ed' across a few files that need it
+# 4. run coccinelle with any per-file changes
+#    There is some ugliness here as we have to do a reverse patch step. Sorry.
+# 5. cp per-file-changes/* to final
+# 6. run coccinelle files that apply to more than one file
+#    it's best to run coccinelle on as many files as possible, she's pretty
+#	smart about
+#    certain transformations, e.g. if you remove a function definition she can
+#    remove all calls to that function (usually)
+#
+# Now you can
+# make (will build all working tools)
+# or
+# make broken
+# for things that don't build yet.
