  "Description": "Provides an R interface to the 'tDelta' C++ library for\nparsing DELTA (DEscription Language for TAxonomy) format files\n<https://freedelta.sourceforge.net>. Supports loading character\nlists, item descriptions, and specifications, with efficient\nsearching and matching of items based on character values. It\nalso supports the generation of identification keys, diagnoses,\nnatural-language descriptions, and clustering and ordination\nanalyses by means of the DELTA programs 'CONFOR', 'KEY', and\n'DIST'.",
