 Here are some of the cpp macros used, together with some short explanation
 of their use.  Feel free to add more macros and more categories.
+Most of these are from config.in, so it's probably better to put the
+explanations in that file.  Ideally, everything would be defined and
+documented in config.in, and this file would not be necessary.
