The extended example says that starting january 2015, things have changed with ePUB, which probably also applies to me as I only recently started with a fresh download of a current ConTeXt mkiv.

I did add this to the environment file and tried to create an ePub for the whole book and for an individual chapter, but no success yet:

luna-wifi:chapters gerben$ (. /usr/local/src/ConTeXt/tex/setuptex && mtxrun --script epub --make c_loosely.specification)
Setting "/usr/local/src/ConTeXt/tex" as ConTeXt root.

mtx-epub        | unknown specificaton file 'c_loosely.specification-export/c_loosely.specification-pub' for 'c_loosely.specification'
luna-wifi:chapters gerben$ (. /usr/local/src/ConTeXt/tex/setuptex && mtxrun --script epub --make prd_book.specification)
Setting "/usr/local/src/ConTeXt/tex" as ConTeXt root.

mtx-epub        | unknown specificaton file 'prd_book.specification-export/prd_book.specification-pub' for 'prd_book.specification'


What am I missing? What is a specification file?
