+dnl These are alternate definitions of some macros, which produce
+dnl strings in the output marked with "@@@" so we can easily extract
+dnl the information we want. The `#' at the end of the first line of
+dnl each definition seems to be necessary to prevent m4 from eating
+dnl the newline, which makes the @@@ not always be at the beginning of
+dnl a line.
