Great, thanks for testing!

By that time I hope to have callgraph generation also working.
It will generated .dot files which can be converted with "dot" tool
(from Graphviz package) to SVG, PostScript, PNG etc.
Just note that the callgraphs can be pretty big, most SVG and PostScript
viewers don't allow large enough zoom levels and as raster images callgraphs
would most likely take too much memory. So you need a viewer that allows
very large zoom factors AND rasterizes just the visible part of the graphs.
Best viewer is this:
http://code.google.com/p/jrfonseca/wiki/XDot
As it can show .dot files directly, without rasterising the whole thing.
Some other useable viewers are:
- DOT: dotty from graphviz package
- SVG: rsvg-view from rsvg-bin package
- PS/PDF: xpdf
- Eero
