+dnl @synopsis AX_CHECK_GLUT
+dnl
+dnl Check for GLUT. If GLUT is found, the required compiler and linker
+dnl flags are included in the output variables "GLUT_CFLAGS" and
+dnl "GLUT_LIBS", respectively. This macro adds the configure option
+dnl "--with-apple-opengl-framework", which users can use to indicate
+dnl that Apple's OpenGL framework should be used on Mac OS X. If
+dnl Apple's OpenGL framework is used, the symbol
+dnl "HAVE_APPLE_OPENGL_FRAMEWORK" is defined. If GLUT is not found,
+dnl "no_glut" is set to "yes".
