+# help you build a list of the places you need to modify when changing a header
+# or other "global" name. The only argument is the pattern you want to search
+# for. It should be quoted to escape shell interpretation of the pattern's
+# special characters.
+#
+# Note that the implementation is based on llvmdo. See that script for more
+# details.
