Performance scripts with SVG

I was asked where I got the tools to make graphs like this one (for this post).  It’s a custom variation on Federico’s Performance Scripts which outputs SVG instead. You can get it here.  It reads in the strace output in the same format as Federico’s scripts, and prints out SVG.  You can use inkscape or whatever you like to mark it up then.  It could probably be improved a whole lot, but I offer it here in case it’s useful.
