Not sure I understand, could you provide an example?

I rarely use lilypond-book, but maybe the following is of some help:

Don't understand. The .toc-file gets its name from the .ly-file where
it is called.
If it's called in qwerty.ly it will be named qwerty.toc
That's coded in the function you linked to.

This output is created by the function. Though, you can change this ofcourse.
Below you'll find a little extended code.
Drawback: you'll need a recent devel-version. Back in 2.18.
markup->string didn't work sufficiently.
Also, it formats the output-lines a bit different (maybe you can
adjust this even more to fit your needs,) and prints to terminal how
the .toc-file is named.
