19"Covered Code" is the source or object code of a version of Autoconf
20that is a covered work under this License.
21
22"Normally Copied Code" for a version of Autoconf means all parts of
23its Covered Code which that version can copy from its code (i.e., not
24from its input file) into its minimally verbose, non-debugging and
25non-tracing output.
26
27"Ineligible Code" is Covered Code that is not Normally Copied Code.
28
291. Grant of Additional Permission.
30
31You have permission to propagate output of Autoconf, even if such
32propagation would otherwise violate the terms of GPLv3.  However, if
33by modifying Autoconf you cause any Ineligible Code of the version you
34received to become Normally Copied Code of your modified version, then
35you void this Exception for the resulting covered work.  If you convey
36that resulting covered work, you must remove this Exception in accordance
37with the second paragraph of Section 7 of GPLv3.
