\include vs \input in lesson-13 for front.tex

[Skillmon]

In the long example file of lesson-13 we use \include{front} and in the text below it (long before any user would have taken a look at the separate files at the end of the page) we describe

In the example, we have used it [the \input command] to separate out the front- and
backcovers, keeping the main file short and clear, and also meaning we could
re-use the covers in another document.

Imho, the example should be changed to use \input{front}, instead of \include{front}. Objections or thoughts?

This would also mean changing the \includeonly statement in that file.

Or we change the description text (to make sure that we don't mean the file front.tex, but the other subfiles \input by front.tex such as frontcover.tex and dedication.tex). I think both would be fine (maybe changing the text is even better), but the current form is easy to misunderstand (in that we have made an error in the example or the text).
