 Let's say you are working on a new version of a library; you add a new
 internal (i.e. non-exposed) module but you forget to update the package
 description. You locally test your changes, everything works fine so you
 install it. Now, since the new module is not listed in {{{other-modules}}}
 it will not be included in the final library. Therefore, when you try to
 use it you get rather cryptic linker errors. It can take a while until you
 realize where the problem is coming from.

 The proposal is to look, during build, for compiled modules under the
 {{{dist}}} directory that are not included in the final library and warn
 the user about  their presence.
