I've gone over the patch as far as it overlaps my patch (i.e. mostly
ignoring the Configuration stuff).  I like it, and I agree that it
goes beyond what I did.

One cosmetic nitpick,

would look better (and follow the other field description's format
closer) as

+libFieldDescrs = map biToLib binfoFieldDescrs
+  ++ [
+      listField "exposed-modules"
+         text               parseModuleNameQ
+         exposedModules     (\mods lib -> lib{exposedModules=mods})
+     ]

Thanks.
