+# This test is for overlapping/shadowing packages with Cabal.  We
+#   1. install p-1.0 to the global DB
+#   2. install q-1.0 (depending on p-1.0) to a temporary DB
+#   3. install a differnet p-1.0 to the temp DB
+#   4. attempt to configure and buidl r, which depends on p-1.0 and q-1.0
+#
+# step 4 will elicit a warning from Cabal's configure step that the
+# packages are inconsistent, and will cause an error from GHC.
+# Currently the error message from GHC is swallowed by Cabal.
