Small grammar, formatting/technical-markup fixes.

* Moved from passive (e.g. "will generate") to active voice (e.g. "generates") == very common writing fix I have to do on myself all the time.
* Shooting for a markup style for technical bits (filenames, program names, directories, etc.) that matches what we'd do in AsciiDoc and upwards to DocBook/Publican == a style we all use makes conversion down the road more easy.
