Publication-quality taxonomic keys with LaTeX

There is a package dichokey available on CTAN, written by Nico Dam in 1998 for constructing indented identification keys in LaTeX.

To complement this useful package, here I provide a second one called bracketkey, also available on CTAN, which is designed to construct bracketed identification keys.
