when launch qtdemo, many demos has warning: "Could not load description. Ensure that the documentation for Qt is built", so it is nice to have those related description built-in. reproduce step: 1. # qtdemo 2. pick one demo, e.g. "Demonstration"->"Composition Modes", check warning message in right side window
