Minor spelling corrections

> The library comes with comprehensible documentation

Should comprehensible be literate? I read it and all I think is "do they mean comprehensive" ?

Maybe "The automated build steps in the prototype include ones that manage the generation of documentation artifacts as a part of the build process in a [literate-programming](http://en.wikipedia.org/wiki/Literate_programming) manner."

(I am off to read the docs now so maybe I'll have a better formulation when I've read those!)
