 DeDRM plugin for calibre (Mac OS X, Windows)
 -------------------------------------------------------
+calibe 5.x and later are now written in Python 3, and plugins must also use Python 3. If you have calibre 5, you must use version 7.x or later of the plugins. For calibre 4.x and earlier, use version 6.8.0 of the plugins.

 The DeDRM plugin for calibre removes DRM from your Kindle and Adobe DRM ebooks when they are imported to calibre. Just install the DeDRM plugin (DeDRM_plugin.zip), following the instructions and configuration directions provided in the ReadMe file and the help links in the plugin's configuration dialogs.
 
 Once installed and configured, you can simply add a DRM book to calibre and a DRM-free version will be imported into the calibre database. Note that DRM removal only occurs on IMPORT not on CONVERSION or at any other time. If you have already imported DRMed books you'll need to remove the books from calibre and re-import them.
