Is there a way to not include the
<meta name="calibre:user_metadata ....
entries in the opf. I would like to retain the dc: entries and the <meta content entries.
Also is there a batch way to strip the <meta name="calibre:user_metadata .... out of my epubs. I know the excellent
Modify ePub plugin has an option to remove non dc: elements but this will strip out the series information that I need as well.
