+# Revision history:
+# 20090902: download from twice
+# 20090903: Weakly assign MACHINE and DISTRO
+# 20090904:  * Don't recreate local.conf is it already exists
+#            * Pass 'unknown' machines to OE directly
+# 20090918: Fix /bin/env location
+#           Don't pass MACHINE via env if it's not set
+#           Changed 'build' to 'bitbake' to prepare people for non-scripted usage
+#           Print bitbake command it executes
+# 20091012: Add argument to accept commit id.
+# 20091202: Fix proxy setup
