- Rebuilt for https://fedoraproject.org/wiki/Fedora_21_22_Mass_Rebuild

* Sat Jun 07 2014 Fedora Release Engineering <rel-eng@lists.fedoraproject.org> - 2.12.4.13-2
- Rebuilt for https://fedoraproject.org/wiki/Fedora_21_Mass_Rebuild

- use license tag for license instead of docs

* Sun Feb 02 2014 Matthew Miller <mattdm@fedoraproject.org> - 2.12.4.13-1
- update to new ultra-minor upstream version. This update includes a
  fix to lucas.cal; if you know what the Lucas primality test is, you
  may want this update, and otherwise you probably do not care.

* Mon Sep 02 2013 Matthew Miller <mattdm@fedoraproject.org> - 2.12.4.12-1
- yet more sample scripts + minor other changes, including ctype-like builtins
- .cal scripts are not linked, so leave those LGPL

- libcalc.so needs to be executable. 

* Tue May  7 2013 Matthew Miller <mattdm@fedoraproject.org> - 2.12.4.7-1
- update to newer development version (minor upstream changes)

* Thu Feb 14 2013 Matthew Miller <mattdm@mattdm.org> - 2.12.4.4-6
- make the license doc conditional more straightforward; old too-clever
  approach was confusing newer rpm
- correct which license file is used when readline isn't selected, in case
  for some reason someone really really wants to avoid conversion to GPL
- fix the date of the first changelog entry to make rpm not whine about it

* Wed Feb 13 2013 Fedora Release Engineering <rel-eng@lists.fedoraproject.org> - 2.12.4.4-5
- Rebuilt for https://fedoraproject.org/wiki/Fedora_19_Mass_Rebuild

- update GPL to new address

* Wed Aug 10 2011 Matthew Miller <mattdm@mattdm.org> - 2.12.4.4-1
- update to 2.12.4.4 (latest unstable, but differences from stable
  are small bugfixes)
- vsnprintf bug fix is accepted upstream, so remove patch

* Tue Feb 08 2011 Fedora Release Engineering <rel-eng@lists.fedoraproject.org> - 2.12.2.1-15
- Rebuilt for https://fedoraproject.org/wiki/Fedora_15_Mass_Rebuild

* Fri Jul 24 2009 Fedora Release Engineering <rel-eng@lists.fedoraproject.org> - 2.12.2.1-14

* Mon Feb 23 2009 Fedora Release Engineering <rel-eng@lists.fedoraproject.org> - 2.12.2.1-13
- Rebuilt for https://fedoraproject.org/wiki/Fedora_11_Mass_Rebuild

* Mon Nov  3 2008 Matthew Miller <mattdm@mattdm.org> - 2.12.4.0-3
- fixed extra vsnprintf crash bug

* Mon Oct 27 2008 Matthew Miller <mattdm@mattdm.org> - 2.12.4.0-2
- entangled readline patch is made obsolete by linking changes in
  readline itself. (readline is still too entangled, but
  that's an upstream problem.)

* Mon Oct 27 2008 Matthew Miller <mattdm@mattdm.org> - 2.12.4.0-1
- update to 2.12.4.0
- upstream has switched to bz2 at my request :)
- some of the entangled-readline-fix stuff is upstream, but for a 
  complete fix some coding is needed. (Also, adding libedit as an option
  would be good -- talk to me for details.)
- patch to disable the custom lib completely is upstream. cool.
- add ALLOW_CUSTOM definition to make install section -- changes to upstream
  makefile mean that if that's missing it now tries to build the custom lib
  at that point.
- upstream now doesn't create the custom dir if ALLOW_CUSTOM is off, so we
  no longer need to clean it up. And same with custhelp. There's still an
  upstream bug where libcustomcalc dangling symlinks are created, though.


* Wed Feb 20 2008 Matthew Miller <mattdm@mattdm.org> - 2.12.2.1-12
- add util-linux as a build prereq

- Remove extra license choice information from package release field to
  properly comply with the packaging guidelines so as to not make Spot sad.
  Put a note in the description instead.
