A new release of this package suite with multiple updates since last release, as well as a few new packages. Check out the README file for an overview of the packages, and look at each package's PDF documentation for more details about each package.
I'll be updating the packages on CTAN, too, so you can get updates from there as well.
To install, simply unzip the relevant .tds.zip files in your local texmf tree. (You can run kpsewhich --var-value='TEXMFHOME' to see where that would be.)
