| Everyone is permitted to copy and distribute verbatim copies | |
| of this license document, but changing it is not allowed. | |
| This Exception is an additional permission under section 7 of the GNU | |
| General Public License, version 3 ("GPLv3"). It applies to a given | |
| file that bears a notice placed by the copyright holder of the file | |
| stating that the file is governed by GPLv3 along with this Exception. | |
| The purpose of this Exception is to allow distribution of Autoconf's | |
| typical output under terms of the recipient's choice (including | |
| proprietary). | |
| 0. Definitions | |
| "Covered Code" is the source or object code of a version of Autoconf | |
| that is a covered work under this License. | |
| "Normally Copied Code" for a version of Autoconf means all parts of | |
| its Covered Code which that version can copy from its code (i.e., not | |
| from its input file) into its minimally verbose, non-debugging and | |
| non-tracing output. | |
| "Ineligible Code" is Covered Code that is not Normally Copied Code. | |
| 1. Grant of Additional Permission. | |
| You have permission to propagate output of Autoconf, even if such | |
| propagation would otherwise violate the terms of GPLv3. However, if | |
| by modifying Autoconf you cause any Ineligible Code of the version you | |
| received to become Normally Copied Code of your modified version, then | |
| you void this Exception for the resulting covered work. If you convey | |
| that resulting covered work, you must remove this Exception in accordance | |
| with the second paragraph of Section 7 of GPLv3. | |
| 2. No Weakening of Autoconf Copyleft. | |
| The availability of this Exception does not imply any general presumption | |
| that third-party software is unaffected by the copyleft requirements of | |
| the license of Autoconf. |
