My impressions are not done yet. If you look at what I checked in
earlier today you will notice I discuss how long it took to figure
stuff out, etc. I am keeping it simple for now but I will discuss
subjective things in more detail at a larger context when I come
closer to reaching a conclusion.

there is against something. And since I have not even made a case for
one DVCS over another it isn't worth worrying about this number quite
