[Wotsap-dev] Wotsap and DOT file export

Hi guys,

I was needing to build the graph for Web-of-Trust, and spend some time downloading keys from keyserver and rendering those with sig2dot. It was before I came across Wotsap, and figured that all the graph info I need is actually there in convenient form. However, I would like to explore the graph before rendering it, so converting .wot to some other graph interchange format is a nice to have feature. I had hacked around wotsap to build .dot file from .wot file, please see attached patch.

I would greatly appreciate if this feature would become the part of your distribution of Wotsap. The code is really straight-forward, but review is appreciated nevertheless.

Thanks, Aleksey.
