re­fcheck – Check ref­er­ences (in fig­ures, ta­ble, equa­tions, etc)

The pack­age checks ref­er­ences in a doc­u­ment, look­ing for num­bered but un­la­belled equa­tions, for la­bels which are not used in the text, for un­used bib­li­og­ra­phy ref­er­ences. It can also dis­play la­bel names in text near cor­re­spond­ing num­bers of equa­tions and/or bib­li­og­ra­phy ref­er­ences.
