+# Purpose: Given the names of C source files this script will print the
+#	   file name, line number, and function name of any function that
+#	   doesn't begin with the letter `h' or `H' as stipulated by the
+#	   HDF5 programming style guide.
+#
+#	   Emacs users can run this script as the compile command and
+#	   use `next-error' (usually bound to M-`) to find each name
+#	   violation.
