+measurements obtained on zooarchaeological material.  Log ratios are used to
+compare the relative (rather than the absolute) dimensions of animals from
+archaeological contexts.  The zoolog package is also able to seamlessly
+integrate data and references with heterogeneous nomenclature, which is
+internally managed by a zoolog thesaurus.")
