I just released Camaelon, a theme engine for GNUstep applications ... and a week ago I had also released the 0.3 version of HelpViewer (an help viewer for GNUstep). Finally ! :-)
You can download Camaelon here : http://www.roard.com/camaelon/
And HelpViewer here : http://www.roard.com/helpviewer/
I also started a small webpage to keep track of articles and tutorials about GNUstep : http://www.roard.com/docs/
... and so I put online the article I co-wrote with Fabien Vallon about GNUstep, previously published in Linux Magazine France :-) (available here : http://www.roard.com/docs/lmf1.article/) Following GNUstep's articles for LMF will be put on-line too.
