# 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
