Overview
This project builds content objects from drupal and bundles them into an
EPUB 3.0 document. Currently it will export a rendered entity seperate of all
of the page markup and gather all the referenced resources within the content
and bundle those into one EPUB document.
That is, this module looks at the content and determines what should be included
in the EPUB document. The actual build process takes place during cron, make
sure to run cron as a user that has access to the content necessary otherwise
the build will fail.
