 extends the range of licensing terms with which the GPL is compatible.  An
 added part carrying additional requirements may be combined with GPL'd code,
 but only if those requirements belong to an set enumerated in GPLv3\S7. There
 are, of course,  limits on the acceptable additional requirements, which to
 ensures that enhanced license compatibility does not
 defeat the broader software-freedom-defending terms of the GPL\@. Unlike terms that grant
 additional permissions, terms that impose additional requirements cannot be
 removed by a downstream user of the combined GPL'd work, because only in the
 pathological case\footnote{Theoretically, a user could collect copyright
   assignment from all known contributors and then do this, but this would
   indeed be the pathological case.}  would a user have the right to do so.
 Under subsections 7a and 7b, the requirements may include preservation of
 copyright notices, information about the origins of the code or alterations
 of the code, and different warranty disclaimers. Under subsection 7c, the
 requirements may include limitations on the use of names of contributors and
 on the use of trademarks for publicity purposes. In general, we permit these
 requirements in added terms because many free software licenses include them
 and we consider them to be unobjectionable. Because we support trademark fair
 use, the limitations on the use of trademarks may seek to enforce only what
 is required by trademark law, and may not prohibit what would constitute fair
 use.
 % FIXME: 7d-f
 % FIXME-LATER: It would be good to have detailed info on each of 7a-f.
 %              Here's some commented-out text that might be useful for 7a-b

 % FIXME:  removing additional restrictions
 % FIXME:  probably mostly still right, needs some updates, though.
 Section 7 requires a downstream user of a covered work to preserve the
 non-GPL terms covering the added parts just as they must preserve the GPL, as
 long as any substantial portion of those parts is present in the user's
 version.
 % FIXME: minor rewrites needed
