14.1 Controlling Help Output
============================

Users consult `configure --help' to learn of configuration decisions
specific to your package.  By default, `configure' breaks this output
into sections for each type of option; within each section, help
strings appear in the order `configure.ac' defines them:

     Optional Features:
       ...
       --enable-bar            include bar

     Optional Packages:
       ...
       --with-foo              use foo

 -- Macro: AC_PRESERVE_HELP_ORDER
     Request an alternate `--help' format, in which options of all
     types appear together, in the order defined.  Call this macro
     before any `AC_ARG_ENABLE' or `AC_ARG_WITH'.

          Optional Features and Packages:
            ...
            --enable-bar            include bar
            --with-foo              use foo
