	27	dnl that constitutes the Autoconf program.
	28	dnl
	29	dnl Certain portions of the Autoconf source text are designed to be copied
	30	dnl (in certain cases, depending on the input) into the output of
	31	dnl Autoconf. We call these the "data" portions. The rest of the Autoconf
	32	dnl source text consists of comments plus executable code that decides which
	33	dnl of the data portions to output in any given case. We call these
	34	dnl comments and executable code the "non-data" portions. Autoconf never
	35	dnl copies any of the non-data portions into its output.

	37	dnl This special exception to the GPL applies to versions of Autoconf
	38	dnl released by the Free Software Foundation. When you make and
	39	dnl distribute a modified version of Autoconf, you may extend this special
	40	dnl exception to the GPL to apply to your modified version as well, unless
	41	dnl your modified version has the potential to copy into its output some
	42	dnl of the text that was the non-data portion of the version that you started
	43	dnl with. (In other words, unless your change moves or copies text from
	44	dnl the non-data portions to the data portions.) If your modification has
	45	dnl such potential, you must delete any notice of this special exception
	46	dnl to the GPL from your modified version.
