Thanks for posting this. Am surprised to have not heard of this project before. It's a bit disappointing that it's not included in either of the Distro's that I use regularly. And even worse that the source for the project is maintained in CVS. It seems like perhaps the project is a tad neglected.
it's in fedora and debian (package name global). what distro do you use? it seems easy to package...
