+  These tests take the following form:
+  DECLARATIONS => Declarations of the templates which are either marked with MOZ_NEEDS_MEMMOVABLE_TYPE
+                  or which instantiate a MOZ_NEEDS_MEMMOVABLE_TYPE through some mechanism.
+  BAD N        => Instantiations of the wrapper template with each of the non-memmovable types.
+                  The prefix S_ means subclass, W_ means wrapped. Each of these rows should produce an error
+                  on the NeedyTemplate in question, and a note at the instantiation location of that template.
+                  Unfortunately, on every case more complicated than bad1, the instantiation location is
+                  within another template. Thus, the notes are expected on the template in question which
+                  actually instantiates the MOZ_NEEDS_MEMMOVABLE_TYPE template.
+  GOOD N       => Instantiations of the wrapper template with each of the memmovable types.
+                  This is meant as a sanity check to ensure that we don't reject valid instantiations of
+                  templates.
+
+
+  Note 1: Each set uses it's own types to ensure that they don't re-use each-other's template specializations.
+  If they did, then some of the error messages would not be emitted (as error messages are emitted for template
+  specializations, rather than for variable declarations)
+
+  Note 2: Every instance of NeedyTemplate contains a member of type T. This is to ensure that T is actually
+  instantiated (if T is a template) by clang. If T isn't instantiated, then we can't actually tell if it is
+  NON_MEMMOVABLE. (This is OK in practice, as you cannot memmove a type which you don't know the size of).
+
+  Note 3: There are a set of tests for specializations of NeedyTemplate at the bottom. For each set of tests,
+  these tests contribute two expected errors to the templates.
