From d6c07925417eaea27c85996bc243f93e27b1bcd0 Mon Sep 17 00:00:00 2001 From: Vincent Sanders Date: Tue, 23 May 2017 11:18:45 +0100 Subject: remove cocoa frontend The cocoa frontend has been broken for a few years and we have no maintainer. It was removed from the CI six months ago and has already bitrotted so it cannot be compiled. --- frontends/cocoa/font.m | 243 ------------------------------------------------- 1 file changed, 243 deletions(-) delete mode 100644 frontends/cocoa/font.m (limited to 'frontends/cocoa/font.m') diff --git a/frontends/cocoa/font.m b/frontends/cocoa/font.m deleted file mode 100644 index 17212fff9..000000000 --- a/frontends/cocoa/font.m +++ /dev/null @@ -1,243 +0,0 @@ -/* - * Copyright 2011 Sven Weidauer - * - * This file is part of NetSurf, http://www.netsurf-browser.org/ - * - * NetSurf is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; version 2 of the License. - * - * NetSurf is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
