+# If you have patches you want patch files outside the aboriginal
+# patch directory to be applied, supply the path here. Paths to the
+# patches are built using the pattern
+#   ${EXTERNAL_PATCH_DIR}/${PACKAGE}/*.patch
+# So one or more patches to apply to linux could be in the
+# ${EXTERNAL_PATCH_DIR}/linux directory and will be applied in sorted
+# order. The path is either absolute or relative to the aboriginal
+# topdir.
