// This allows us to tell Readium about the book by passing the name of the folder using the ?ePUB=
// URL parameter. It doesn't work to use the original Readium file and make the parameter a full path.
// It's possible that there is some variation that would work, e.g., make the param a full file:/// url
// to the book folder. It's also possible we could get away with only copying the HTML file itself,
// if we modified it to have localhost: links to the JS and CSS. Haven't tried this yet. The current
// approach at least works.
