Outputting Files
================

   Every Autoconf script, e.g., `configure.ac', should finish by
calling `AC_OUTPUT'.  It is the macro that generates `config.status',
which will create the `Makefile's and any other files resulting from
configuration.  The only required macro is `AC_INIT' (Note: Input).

 - Macro: AC_OUTPUT
     Generate `config.status' and launch it.  Call this macro once, at
     the end of `configure.ac'.

     `config.status' will take all the configuration actions: all the
     output files (see Note: Configuration Files, macro
     `AC_CONFIG_FILES'), header files (see Note: Configuration
     Headers, macro `AC_CONFIG_HEADERS'), commands (see Note:
     Configuration Commands, macro `AC_CONFIG_COMMANDS'), links (see
     Note: Configuration Links, macro `AC_CONFIG_LINKS'),
     subdirectories to configure (see Note: Subdirectories, macro
     `AC_CONFIG_SUBDIRS') are honored.

   Historically, the usage of `AC_OUTPUT' was somewhat different.
Note: Obsolete Macros, for a description of the arguments that
`AC_OUTPUT' used to support.

   If you run `make' on subdirectories, you should run it using the
`make' variable `MAKE'.  Most versions of `make' set `MAKE' to the name
of the `make' program plus any options it was given.  (But many do not
include in it the values of any variables set on the command line, so
those are not passed on automatically.)  Some old versions of `make' do
not set this variable.  The following macro allows you to use it even
with those versions.

 - Macro: AC_PROG_MAKE_SET
     If `make' predefines the variable `MAKE', define output variable
     `SET_MAKE' to be empty.  Otherwise, define `SET_MAKE' to contain
     `MAKE=make'.  Calls `AC_SUBST' for `SET_MAKE'.

   To use this macro, place a line like this in each `Makefile.in' that
runs `MAKE' on other directories:

     @SET_MAKE@
