Contrary to config.status, it doesn't use CONFIG_FILES or CONFIG_HEADERS

be given to generate several files at the same time.
Without the -n option, this program acts as config.status and considers
the current directory as the top object directory, even when config.status

Unlike config.status behaviour with CONFIG_FILES and CONFIG_HEADERS,
but like config.status behaviour with --file and --header, providing
files or headers on the command line inhibits the default generation of
files when given headers and headers when given files.
Unlike config.status, the FILE:TEMPLATE syntax is not supported for
files and headers. The template is always the filename suffixed with
'.in', in the corresponding directory under the top source directory.

Contrary to config.status, it doesn't use CONFIG_FILES or CONFIG_HEADERS
variables, but like config.status from autoconf 2.6, single files may be
generated with the --file and --header options. Several such options can
be given to generate several files at the same time.
Without the -n option, this program acts as config.status and considers
the current directory as the top object directory, even when config.status
is in a different directory. It will, however, treat the directory
containing config.status as the top object directory with the -n option,
while files given to the --file and --header arguments are considered
relative to the current directory.
The --recheck option, like with the original config.status, runs configure
again, with the options given in the "ac_configure_args" subst.
The options to this function are passed when creating the
ConfigEnvironment, except for files and headers, which contain the list
of files and headers to be generated by default. These lists, as well as
the actual wrapper script around this function, are meant to be generated
by configure. See build/autoconf/config.status.m4.
Unlike config.status behaviour with CONFIG_FILES and CONFIG_HEADERS,
but like config.status behaviour with --file and --header, providing
files or headers on the command line inhibits the default generation of
files when given headers and headers when given files.
Unlike config.status, the FILE:TEMPLATE syntax is not supported for
files and headers. The template is always the filename suffixed with
'.in', in the corresponding directory under the top source directory.
