+/**
+ * \file vao-01.c
+ *
+ * Simple test of APPLE_vertex_array_object functionality.  This test creates
+ * a VAO, pushed it (via \c glPushClientAttrib), modifies the VAO, then pops
+ * it (via \c glPopClientAttrib).  After popping, the state of the VAO is
+ * examined.
+ * 
+ * According the the APPLE_vertex_array_object spec, the contents of the VAO
+ * should be restored to the values that they had when pushed.
+ *
