This package adds forward-referencing to the cleveref package. Any label can be referenced with the new optional argument UsedOn passed to \cref. Doing so, it will print an info message at the original label location (in a theorem environment, say) which reads ``Used on pages ⟨list of pages⟩.'. This functionality is complementary to pagebackref option from hyperref or backref option from biblatex for the bibliography. It might be useful for authors of longer texts such as textbooks or theses, where a lot of supplementary results and information are given in early chapters, appendices or exercises. The message on which pages these results will be used can be a helpful information for the reader of the final text.
