Hello,

I'm happy to announce the release of DoX version 2.0.

What's new in this version: * Optional argument to \doxitem * Optional argument to \Describe<Item> and the <Item> environment * Extend \DescribeMacro, \DescribeEnv and their corresponding environments

The doc package provides LaTeX developers with means to describe the usage and the definition of new commands and environments. However, there is no simple way to extend this functionality to other items (options or counters for instance). DoX is designed to circumvent this limitation, and provides some improvements over the existing functionality as well.

Grab it directly here: http://www.lrde.epita.fr/~didier/software/latex.php#dox

or wait until it propagates through CTAN...
