From 68fc4b415e322f6744299e39864fbc377c6eff74 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 21 May 2010 09:32:38 -0700 Subject: Remove demos that have moved to git+ssh://git.freedesktop.org/git/mesa/demos. The remaining programs are ones I've had difficulty finding a build environment for to make the build system or are unit tests that should probably live next to their code instead. Hopefully people can bring over the build for remaining pieces they care about. --- progs/xdemos/xfont.c | 206 --------------------------------------------------- 1 file changed, 206 deletions(-) delete mode 100644 progs/xdemos/xfont.c (limited to 'progs/xdemos/xfont.c') diff --git a/progs/xdemos/xfont.c b/progs/xdemos/xfont.c deleted file mode 100644 index 2585aa6447..0000000000 --- a/progs/xdemos/xfont.c +++ /dev/null @@ -1,206 +0,0 @@ - -/* - * Mesa 3-D graphics library - * - * Copyright (C) 1999 Brian Paul All Rights Reserved. - * - * Permission is hereby granted, free of charge, to any person obtaining a - * copy of this software and associated documentation files (the "Software"), - * to deal in the Software without restriction, including without limitation - * the rights to use, copy, modify, merge, publish, distribute, sublicense, - * and/or sell copies of the Software, and to permit persons to whom the - * Software is furnished to do so, subject to the following conditions: - * - * The above copyright notice and this permission notice shall be included - * in all copies or substantial portions of the Software. - * - * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS - * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, - * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
