+ This file is in the public domain.
+
+ Descriptive text for the C preprocessor macros that
+ the distributed Autoconf macros can define.
+ No software package will use all of them; autoheader copies the ones
+ your configure.in uses into your configuration header file templates.
+
+ The entries are in sort -df order: alphabetical, case insensitive,
+ ignoring punctuation (such as underscores). Although this order
+ can split up related entries, it makes it easier to check whether
+ a given entry is in the file.
+
+ Leave the following blank line there!! Autoheader needs it. */
