 buildconf: generates the files needed to configure httpd.

 Configuration:
   -h, --help               display this help and exit

   --with-apr=SRCDIR        define a space-separated list of directories to
                            search for the APR source code. If, instead of a
                            directory, an apr-config executable name is passed,
                            APR-Config Mode is enabled (see below). Defaults to
                            "srclib/apr ../apr"
   --with-apr-util=SRCDIR   define a space-separated list of directories to
                            search for the APR-util source code. Defaults to the
                            same location as the --with-apr SRCDIR, but with
                            "apr" replaced with "apr-util" or "aprutil". Ignored
                            in APR-Config Mode.

   --with-regen-expr        suppress the timestamp adjustment which prevents the
                            rebuild of the ap_expr expression parser

 APR-Config Mode:

   When passing an apr-config executable to --with-apr, buildconf will attempt to
   copy build scripts from various installed locations on your system instead of
   an APR source tree. This allows you to configure httpd from source without
   also requiring you to download the APR and/or APR-util sources.

   For example:

       ./buildconf --with-apr=apr-1-config

   For this functionality to work reliably, you must have automake >= 1.12 and be
   using a distribution that includes both find_apr.m4 and find_apu.m4 in the
   --installbuilddir pointed to by apr-config.
