##### LaTeXdtxdescribe package

The doc package includes tools for describing macros and environments in source dtx format. The dtxdescribe package adds additional tools for describing booleans, lengths, counters, keys, packages, classes, options, files, commands, arguments, and other objects.

Each item is given a margin tag similar to \DescribeEnv, and is listed in the index by itself and also by category. Each item may be sorted further by an optional class. All index entries except code lines are hyperlinked.

Descriptions are best accompanied by examples, so the environment dtxexample is provided. Contents are displayed verbatim along with a caption and cross-referencing. They are then \input and executed, and the result is shown.
