|

#

|
# All credit given to The Dark Reverser for the original standalone script.
|
|
# I had the much easier job of converting it to Calibre a plugin.
|
|
#
|
|
# This plugin is meant to convert secure Ereader files (PDB) to unsecured PMLZ files.
|
|
# Calibre can then convert it to whatever format you desire.
|
|
# It is meant to function without having to install any dependencies...
|
|
# other than having Calibre installed, of course. I've included the psyco libraries
|
|
# (compiled for each platform) for speed. If your system can use them, great!
|
|
# Otherwise, they won't be used and things will just work slower.
|
|
#
|
|
# Installation:
|
|
# Go to Calibre's Preferences page... click on the Plugins button. Use the file
|
|
# dialog button to select the plugin's zip file (eReaderPDB2PML_vXX_plugin.zip) and
|
|
# click the 'Add' button. You're done.
|
|
#
|
|
# Configuration:
|
|
# Highlight the plugin (eReader PDB 2 PML) and click the
|
|
# "Customize Plugin" button on Calibre's Preferences->Plugins page.
|
|
# Enter your name and the last 8 digits of the credit card number separated by
|
|
# a comma: Your Name,12341234
|
|
#
|
|
# If you've purchased books with more than one credit card, separate the info with
|
|
# a colon: Your Name,12341234:Other Name,23452345
|
|
# NOTE: Do NOT put quotes around your name like you do with the original script!!
|
|

|
|
# Revision history:
|
|
# 0.0.1 - Initial release
|
|
# 0.0.2 - updated to distinguish it from earlier non-openssl version
