 // check the complex case described in the hp paper by playing through all
 // sorts of arrangements of finite elements on one coarse and one refined cell
+//
+// this code in particular tests some compensating code in
+// dof_tools.cc, where we have to make sure that we select a suitable
+// set of master dofs. this is mostly trivial in 2d and for most fe
+// combinations in 3d as well. the exceptions are that it doesn't work
+// as easily in 3d for the combinations Q4/Q3, Q5/Q3, and
+// Q5/Q4. Higher order finite elements in 3d will probably only
+// exacerbate the problem, but the code there appears to be robust.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
