Tharsis.prof 0.1: a frame-based profiler for game development

[Andrei Alexandrescu via Digitalmars-d-announce]

This looks like solid work, congratulations! Could someone please 
announce this on reddit and hackernews on Monday morning?

We'd need one of the blog posts to be the entry point leading to the 
others and to the code examples. Which one would be it?
