# 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
|
||
# Special thanks to The Dark Reverser for MobiDeDrm and CMBDTC for cmbdtc_dump
|
||
# from which this script borrows most unashamedly.
