+GLUT State
+
+ 23.0
+"freeglut.h" Header File
+
+
+
+Application programmers who are porting their GLUT programs to freeglut may continue
+to include <GL/glut.h> in their programs.
+Programs which use the freeglut-specific extensions to GLUT should include
+<GL/freeglut.h>. One possible arrangement is as follows:
+
+
+
+#ifdef FREEGLUT
+#include <GL/freeglut_ext.h>
+#else
+#include <GL/glut.h>
+#endif
+
+
+
+Compile-time freeglut version testing can be done as follows:
+
+
+
+#ifdef FREEGLUT_VERSION_2_0
+ code specific to freeglut 2.0 or later here
+#endif
+
+
+
+In future releases, FREEGLUT_VERSION_2_1, FREEGLUT_VERSION_2_2, etc will
+be defined. This scheme mimics OpenGL conventions.
+
+
+
+The freeglut version can be queried at runtime by calling
+glutGet(GLUT_VERSION).
+The result will be X*10000+Y*100+Z where X is the major version, Y is the
+minor version and Z is the patch level.
+
+
+This may be used as follows:
+
+
+
+if (glutGet(GLUT_VERSION) < 20001) {
+ printf("Sorry, you need freeglut version 2.0.1 or later to run this program.\n");
+ exit(1);
