# engine to remove drm from Kindle for Mac and Kindle for PC books
|
|
# for personal use for archiving and converting your ebooks
|
|
|
|
# PLEASE DO NOT PIRATE EBOOKS!
|
|
|
|
# We want all authors and publishers, and eBook stores to live
|
|
# long and prosperous lives but at the same time we just want to
|
|
# be able to read OUR books on whatever device we want and to keep
|
|
# readable for a long, long time
|
|
|
|
# This borrows very heavily from works by CMBDTC, IHeartCabbages, skindle,
|
|
# unswindle, DarkReverser, ApprenticeAlf, DiapDealer, some_updates
|
|
# and many many others
|
|
|
|
# It can run standalone to convert K4M/K4PC/Mobi files, or it can be installed as a
|
|
# plugin for Calibre (http://calibre-ebook.com/about) so that importing
|
|
# K4 or Mobi with DRM is no londer a multi-step process.
|
|
#
|
|
# ***NOTE*** If you are using this script as a calibre plugin for a K4M or K4PC ebook
|
|
# then calibre must be installed on the same machine and in the same account as K4PC or K4M
|
|
# for the plugin version to function properly.
|
|
#
|
|
# To create a Calibre plugin, rename this file so that the filename
|
|
# ends in '_plugin.py', put it into a ZIP file with all its supporting python routines
|
|
# and import that ZIP into Calibre using its plugin configuration GUI.
