BrailleBlaster may need to handle zipped archives more directly. It
looks like liblouisutdml will also need that functionality. It will
decide which files to use by looking at the manifest for Daisy or epub
or simply chosing the file based on the archive type, as in the case of
docx files . There would be a new configuration setting archivetype .
For both BrailleBlaster and liblouisutdml there is the problem of
combining different files. For example, in epub archives, each chapter
is in a different file. How are these combined to get a single file for
a book? That is what we would want.
