[PATCH 2/3] qh: Fall for peer pressure from myself, and implement some help

[robin.sonefors at op5.com]

From: Robin Sonefors <robin.sonefors at op5.com>

This is still quite sparse, as it's intended as inline help and hints,
rather than as complete documentation, but it should still prove
helpful.
