Hi, At the moment, Pillar assumes that one file is one chapter. When generating PDF, an index .tex file is required to construct the overall book with table of contents and others such elements. As far as I see, in HTML, there is no possibility of generating this Is there a plan to extend Pillar to support a book with multiple files? What about references? I saw somewhere that there existed an intention of supporting references, but I did not see an example yet. Are they supported? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"
