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. */
