Thank you for the LyX (how to put in a book)

[Sasa Janiska]

Hello!

I am finishing one book of my mother (her biography), there will be two
editions (Croatian and English) and I would like to mention that the
book is prepared with Lyx & LaTeX, expressing our gratefullness to the
developers and the whole idea of free software.

How to do it properly? (Something like: "The layout for this book is
made with LyX (LaTeX) ..."
Sincerely,
Sasa
