+#!/bin/bash
+#
+# This script attempts to repair the use of creating
+# dependency graphs of packages.
+#
+# This got unusuable, (and broken beyond repair?) with
+# enhancements to bitbake in its dependency tracking.
+#
+# This script is a hack. It works for me.
+#
+# Apply the patch from this bug report to bitbake
+# (if not yet upstream), tested against r1152 of
+# svn://svn.berlios.de/bitbake/branches/bitbake-1.8
