Module:Autotaxobox

--[[ This module provides support to the automated taxobox system – the templates Automatic taxobox, Speciesbox, Subspeciesbox, Infraspeciesbox, etc.

In particular it provides a way of traversing the taxonomic hierarchy encoded in taxonomy templates (templates with names of the form "Template:Taxonomy/TAXON_NAME") without causing template expansion depth errors. ]]
