Configuration requirements
==========================

   The simplest way to meet the basic Automake requirements is to use
the macro `AM_INIT_AUTOMAKE' (Note: Macros).  But if you prefer, you
can do the required steps by hand:

   * Define the variables `PACKAGE' and `VERSION' with `AC_SUBST'.
     `PACKAGE' should be the name of the package as it appears when
     bundled for distribution.  For instance, Automake defines `PACKAGE'
     to be `automake'.  `VERSION' should be the version number of the
     release that is being developed.  We recommend that you make
     `configure.in' the only place in your package where the version
     number is defined; this makes releases simpler.

     Automake doesn't do any interpretation of `PACKAGE' or `VERSION',
     except in `Gnits' mode (Note: Gnits).

   * Use the macro `AC_ARG_PROGRAM' if a program or script is installed.
     *Note Transforming Program Names When Installing:
     (autoconf)Transforming Names.

   * Use `AC_PROG_MAKE_SET' if the package is not flat.  Note: Creating
     Output Files.

   * Use `AM_SANITY_CHECK' to make sure the build environment is sane.

   * Call `AC_PROG_INSTALL' (*note Particular Program Checks:
     (autoconf)Particular Programs.).

   * Use `AM_MISSING_PROG' to see whether the programs `aclocal',
     `autoconf', `automake', `autoheader', and `makeinfo' are in the
     build environment.  Here is how this is done:
          missing_dir=`cd $ac_aux_dir && pwd`
          AM_MISSING_PROG(ACLOCAL, aclocal, $missing_dir)
          AM_MISSING_PROG(AUTOCONF, autoconf, $missing_dir)
          AM_MISSING_PROG(AUTOMAKE, automake, $missing_dir)
          AM_MISSING_PROG(AUTOHEADER, autoheader, $missing_dir)
          AM_MISSING_PROG(MAKEINFO, makeinfo, $missing_dir)

   Here are the other macros which Automake requires but which are not
run by `AM_INIT_AUTOMAKE':

`AC_OUTPUT'
     Automake uses this to determine which files to create (Note:
     Creating Output Files.).  Listed files named
     `Makefile' are treated as `Makefile's.  Other listed files are
     treated differently.  Currently the only difference is that a
     `Makefile' is removed by `make distclean', while other files are
     removed by `make clean'.
