|

#
|
||||
# All credit given to i♥cabbages and The Dark Reverser for the original standalone scripts.
|
||||
# We had the much easier job of converting them to a calibre plugin.
|
||||
#
|
||||
# This plugin is meant to decrypt eReader PDBs, Adobe Adept ePubs, Barnes & Noble ePubs,
|
||||
# Adobe Adept PDFs, Amazon Kindle and Mobipocket files without having to
|
||||
# install any dependencies... other than having calibre installed, of course.
|
||||
#
|
||||
# Configuration:
|
||||
# Check out the plugin's configuration settings by clicking the "Customize plugin"
|
||||
# button when you have the "DeDRM" plugin highlighted (under Preferences->
|
||||
# Plugins->File type plugins). Once you have the configuration dialog open, you'll
|
||||
# see a Help link on the top right-hand side.
