+    Test that the $ROOT variable is used according to the Package
+    Manager Specification (PMS).
+
+    All currently-approved versions of the PMS state that the $ROOT
+    variable is legal only in the pkg_* phases. One common misuse is
+    to use $ROOT instead of $EPREFIX as "something more general than a
+    front-slash" in the src_* functions. We want to detect these
+    mistakes, and eventually eliminate all uses of $ROOT outside of
+    the PMS-defined pkg_* phases.
