GNU General Public License v3.0 or later with Autoconf exception 3.0

The same license with an exception of GPL-3.0-or-later. A variant models the same legal text with one thing changed, so it is a license of its own with an address of its own and it is listed like any other.

Also known as GNU General Public License v3.0 or later with Autoconf exception 3.0, GPL-3.0+ with Autoconf exception, GPL-3.0-or-later WITH Autoconf-exception-3.0, GPL-3.0-or-later-with-Autoconf-exception-3.0, GPLv3 or later with Autoconf exception.

Additional clauses

AUTOCONF CONFIGURE SCRIPT EXCEPTION Version 3.0, 18 August 2009 Copyright © 2009 Free Software Foundation, Inc. <http://fsf.org/> 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.

History

This license model has 2 versions. Version 2 is the one served today; every earlier version keeps its own address, so a conclusion drawn from one of them can still be checked against it.

  1. Version 2 current2026-09-24 Giray Havur

    The changes since version 1 left endorsement to the default rule of the core dependency graph, recorded which sentence of the text each statement rests on, corrected it against its text on 2026-09-24 and named the license the record itself is published under.

      Manual edit The first half of the Section 4 sentence, "You may charge any price or no price for each copy that you convey", is the permission to charge for a copy, not a warranty clause.

      Manual edit Every record is published under CC BY 4.0. cc:license names the record DALICC keeps of that licence; dct:license now names it by the address Creative Commons publishes it at, so that a consumer matching the canonical IRI finds it.

Every change names the reason behind it: a finding of the content review, one of its library-wide decisions, the metadata that review wrote onto every record, or a hand edit. None of it is legal advice.

Nothing on this page is legal advice. What a license means is decided by its text; ask a legal advisor before you rely on it.
