#
# This is a WINDOWS python script. You need a Python interpreter to run it.
# For example, ActiveState Python, which exists for windows.
#
# It can run standalone to convert K4PC files, or it can be installed as a
# plugin for Calibre (http://calibre-ebook.com/about) so that importing
# K4PC files with DRM is no londer a multi-step process.
#
# ***NOTE*** Calibre and K4PC must be installed on the same windows machine
# 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 and import that ZIP into Calibre
# using its plugin configuration GUI.
#
# Thanks to The Dark Reverser for MobiDeDrm and CMBDTC for cmbdtc_dump from
# which this script steals most unashamedly.
#
# Changelog
# 0.01 - Initial version - Utilizes skindle and CMBDTC method of obtaining
# book specific pids from K4PC books. If Calibre and K4PC are installed
# on the same windows machine, Calibre plugin functionality is once
# again restored.

Plugin for K4PC, K4Mac and Mobi Books
Will work on Linux (standard DRM Mobi books only), Mac OS X (standard DRM Mobi books and "Kindle for Mac" books, and Windows (standard DRM Mobi books and "Kindle for PC" books.
This plugin supersedes MobiDeDRM, K4DeDRM, and K4PCDeDRM plugins. If you install this plugin, those plugins can be safely removed.
This plugin is meant to convert "Kindle for PC", "Kindle for Mac" and "Mobi" ebooks with DRM to unlocked Mobi files. Calibre can then convert them to whatever format you desire. It is meant to function without having to install any dependencies except for Calibre being on your same machine and in the same account as your "Kindle for PC" or "Kindle for Mac" application if you are going to remove the DRM from those types of books.
Installation:
Go to Calibre's Preferences page... click on the Plugins button. Use the file dialog button to select the plugin's zip file (k4mobidedrm_vXX_plugin.zip) and click the 'Add' button. You're done.
Configuration:
Highlight the plugin (K4MobiDeDRM under the "File type plugins" category) and click the "Customize Plugin" button on Calibre's Preferences->Plugins page. Enter a comma separated list of your 10 digit PIDs. This is not needed if you only want to decode "Kindle for PC" or "Kindle for Mac" books.
Troubleshooting:
If you find that it's not working for you (imported azw's are not converted to mobi format), you can save a lot of time and trouble by trying to add the azw file to Calibre with the command line tools. This will print out a lot of helpful debugging info that can be copied into any online help requests. I'm going to ask you to do it first, anyway, so you might
as well get used to it. ;)
Open a command prompt (terminal) and change to the directory where the ebook you're trying to import resides. Then type the command "calibredb add your_ebook.azw". Don't type the quotes and obviously change the 'your_ebook.azw' to whatever the filename of your book is. Copy the resulting output and paste it into any online help request you make.
** Note: the Mac version of Calibre doesn't install the command line tools by default. If you go to the 'Preferences' page and click on the miscellaneous button, you'll see the option to install the command line tools.

K4PCDeDRM - K4PCDeDRM_X.XX_plugin.zip
Requires Calibre version 0.6.44 or higher.
This work is based on the work of cmbtc, skindle, mobidedrm. and skindleAll I had the much easier job of converting them to a Calibre plugin.
This plugin is meant to Kindle for PC azw ebooks that are protected
with Amazon's Mobi based encryption. It is meant to function without having to install any dependencies... other than having both Calibre installed and Kindle for PC on the same machine, of course.
Installation:
Go to Calibre's Preferences page... click on the Plugins button. Use the file dialog button to select the plugin's zip file (K4PCDeDRM_X.XX_plugin.zip) and click the 'Add' button. you're done.

eReader PDB2PML - eReaderPDB2PML_vXX_plugin.zip
All credit given to The Dark Reverser for the original standalone script. I had the much easier job of converting it to a Calibre 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 under the "File type plugins" category) and click the "Customize Plugin" button on Calibre's Preferences->Plugins page. Enter your name and 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!!)
Troubleshooting:
If you find that it's not working for you (imported pdb's are not converted to pmlz format), you can save a lot of time and trouble by trying to add the pdb to Calibre with the command line tools. This will print out a lot of helpful debugging info that can be copied into any online help requests. I'm going to ask you to do it first, anyway, so you might
as well get used to it. ;)
Open a command prompt (terminal) and change to the directory where the ebook you're trying to import resides. Then type the command "calibredb add your_ebook.pdb". Don't type the quotes and obviously change the 'your_ebook.pdb' to whatever the filename of your book is. Copy the resulting output and paste it into any online help request you make.
** Note: the Mac version of Calibre doesn't install the command line tools by default. If you go to the 'Preferences' page and click on the miscellaneous button, you'll see the option to install the command line tools.

MobiDeDRM - MobiDeDRM_X.XX_plugin.zip
Requires Calibre version 0.6.44 or higher.
This work is based on the current mobidedrm.py code.
This plugin is meant to Mobipocket and Kindle ebooks that are protected
with Amazon's Mobi based encryption. It is meant to function without having to install any dependencies... other than having both Calibre installed. You must know the PID orf the device you are using or the book specific PID to use this plugin.
Installation:
Go to Calibre's Preferences page... click on the Plugins button. Use the file dialog button to select the plugin's zip file (MobiDeDRM_X.XX_plugin.zip) and click the 'Add' button.
Then enter your PIDS in the plugin customization window separated by commas (with no spaces).

# 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.

2. Place LZskindle4PCv1_1.exe and skindle.exe in this folder.
3. Create 2 subfolders: C:\skindle\input
and C:\skindle\output
To run:
1. Copy the book(s) you wish to remove DRM from into the input directory
(leave the originals in my kindle folder).
2. Double click on LZskindle4PCv1_0.exe
3. A DOS window will open and will show skindle being called for
each book in the input directory.
4. The books with the DRM removed will now be in the output directory.
Rev1_1
fixed program to allow any file extension. My testing indicates that
skindle does not care what file extension a file has. If it is a file type
that it can convert it will. If the file is not compatible it will close
and give an unknown file type message.
Rev1_0
If the program is run with no files in the input directory you will get a
“File not Found” error and the program will terminate.
PLEASE USE ONLY FOR YOUR PERSONAL USE – ON BOOKS YOU PAID FOR!!
This program is provided to allow you to archive your library in a format that
will outlast the kindle. Technology moves on and you should not have to reinvest
in an entire new library when the Kindle is obsolete. Please do not use this program
for piracy.

Ezskindle4PC.exe
This executable program makes using skindle easier for people using Windows PC’s.
I do not know if it will work under any other operating system, however, I have included
the source code should anyone want to port it into other operating systems.
To use this program:
1. Copy the ezskindle4PC.exe into the same directory with the skindle files.
2. Copy the kindle book into the same directory.
3. double click the EZskindle4PCv1_0.exe file.
a. A DOS window will open and you will be asked for the name of the file you want to work with.
4. Type in the book’s file name. (it will look something like B000WCTBTA_EBOK.prc)
5. The program will then check if it is a Topaz file and then create the output file name using the
first part of the input file name. It will use “tpz” file extension for Topaz books and will use “azw”
for non topaz books. The files with the “azw” format can be converted to other ebook formats using
Calibre. If you want to convert Topaz books to other formats you need to use Topaz tools not skindle.
6. The program will then create a command line and call the skindle program to process the book and
remove the DRM.
7. The program will pause and allow you to see the result of the skindle process.
8. Press any key to close the program.
version 1.1
Ok
Found a new 32 bit compiler and I think I have worked out the kinks.

Readme.txt
- LZskindle4PC is a front end for running skindle that makes it easier for some people who do not like command lines to use it.
- skindle has completely reverse engineered how the book specific PID is generated for Kindle4PC so it can be very useful when new version of Kindle4PC are released and unswindle has not yet been updated. Unfortunately, skindle has some minor bugs that can actually result in corrupted eBooks. No one has yet tracked them down and fixed them. Until they do, use at your own risk.
- unswindle can be used to find the book specific PID but it needs to be updated for each version of Kindle4PC that Amazon releases (and therefore is also useful for Linux users who have Wine). This program “patches” the Kindle4PC executable and therefore is very release specific.
Unfortunately unswindle v7 the latest, has not been updated to work with the latest version of Kindle for PC. You will need to find one of the older versions of Kindle4PC and prevent later updates in order to use this tool.

/*
What: KindleForPC DRM removal utility to preserve your fair use rights!
Why: Fair use is a well established doctrine, and I am no fan of vendor
lockin.
How: This utility implements the PID extraction, DRM key generation and
decryption algorithms employed by the KindleForPC application. This
is a stand alone app that does not require you to determine a PID on
your own, and it does not need to run KindleForPC in order to extract
any data from memory.
Shoutz: The DarkReverser - thanks for mobidedrm! The last part of this
is just a C port of mobidedrm.
labba and I<3cabbages for motivating me to do this the right way.
You guys shouldn't need to spend all your time responding to all the
changes Amazon is going to force you to make in unswindle each time
the release a new version.
CMBDTC - nice work on the topaz break!
Lawrence Lessig - You are my hero. 'Nuff said.
Cory Doctorow - A voice of reason in a sea of insanity
Thumbs down: Disney, MPAA, RIAA - you guys suck. Making billions off
of the exploitation of works out of copyright while vigourously
pushing copyright extension to prevent others from doing the same
is the height of hypocrasy.
Congress - you guys suck too. Why you arrogant pricks think you
are smarter than the founding fathers is beyond me.
*/
Rationale:
Need a tool to enable fair use of purchased ebook content.
Need a tool that is not dependent on any particular version of
KindleForPC and that does not need to run KindleForPC in order to
extract a PID. The tool documents the structure of the kindle.info
file and the data and algorthims that are used to derive per book
PID values.
Installing:
A compiled binary is included. Though it was built using cygwin, it
should not require a cygwin installation in order to run it. To build
from source, you will need cygwin with gcc and make.
This has not been tested with Visual Studio, though you may be able to
pile all the files into a project and add the Crypt32.lib, Advapi32 and
zlib1 dependencies to build it.
usage: ./skindle [-d] [-v] -i <ebook file> -o <output file> [-k kindle.info file] [-p pid]
-d optional, for topaz files only, produce a decompressed output file
-i required name of the input mobi or topaz file
-o required name of the output file to generate
-k optional kindle.info path
-v dump the contents of kindle.info
-p additional PID values to attempt (can specifiy multiple times)
You only need to specify a kindle.info path if skindle can't find
your kindle.info file automatically

Independent implementation of MD5 (RFC 1321).
This code implements the MD5 Algorithm defined in RFC 1321, whose
text is available at
http://www.ietf.org/rfc/rfc1321.txt
The code is derived from the text of the RFC, including the test suite
(section A.5) but excluding the rest of Appendix A. It does not include
any code or documentation that is identified in the RFC as being
copyrighted.
The original and principal author of md5.c is L. Peter Deutsch
<ghost@aladdin.com>. Other authors are noted in the change history
that follows (in reverse chronological order):
2002-04-13 lpd Clarified derivation from RFC 1321; now handles byte order
either statically or dynamically; added missing #include <string.h>
in library.
2002-03-11 lpd Corrected argument list for main(), and added int return
type, in test program and T value program.
2002-02-21 lpd Added missing #include <stdio.h> in test program.
2000-07-03 lpd Patched to eliminate warnings about "constant is
unsigned in ANSI C, signed in traditional"; made test program
self-checking.
1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5).
1999-05-03 lpd Original version.

Independent implementation of MD5 (RFC 1321).
This code implements the MD5 Algorithm defined in RFC 1321, whose
text is available at
http://www.ietf.org/rfc/rfc1321.txt
The code is derived from the text of the RFC, including the test suite
(section A.5) but excluding the rest of Appendix A. It does not include
any code or documentation that is identified in the RFC as being
copyrighted.
The original and principal author of md5.h is L. Peter Deutsch
<ghost@aladdin.com>. Other authors are noted in the change history
that follows (in reverse chronological order):
2002-04-13 lpd Removed support for non-ANSI compilers; removed
references to Ghostscript; clarified derivation from RFC 1321;
now handles byte order either statically or dynamically.
1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
added conditionalization for C++ compilation from Martin
Purschke <purschke@bnl.gov>.
1999-05-03 lpd Original version.

What: KindleForPC DRM removal utility to preserve your fair use rights!
Why: Fair use is a well established doctrine, and I am no fan of vendor
lockin.
How: This utility implements the PID extraction, DRM key generation and
decryption algorithms employed by the KindleForPC application. This
is a stand alone app that does not require you to determine a PID on
your own, and it does not need to run KindleForPC in order to extract
any data from memory.
Shoutz: The DarkReverser - thanks for mobidedrm! The last part of this
is just a C port of mobidedrm.
labba and I<3cabbages for motivating me to do this the right way.
You guys shouldn't need to spend all your time responding to all the
changes Amazon is going to force you to make in unswindle each time
the release a new version.
Lawrence Lessig - You are my hero. 'Nuff said.
Thumbs down: Disney, MPAA, RIAA - you guys suck. Making billions off
of the exploitation of works out of copyright while vigourously
pushing copyright extension to prevent others from doing the same
is the height of hypocrasy.
Congress - you guys suck too. Why you arrogant pricks think you
are smarter than the founding fathers is beyond me.

From Apprentice Alf's Blog:
When Amazon released Kindle for PC, there was a lot of interest in finding the PID used by an installed copy. Unfortunately, it turned out that Amazon had taken the opportunity to increase the complexity of the DRM applied to ebooks downloaded for use with Kindle for PC. In short, every book has its own PID.
The current best method is a script called K4PCDeDRM.py, which takes code from several previous tools and puts them together, giving a one-script solution to removing the DRM that is not dependent on the exact version of the Kindle for PC software.
To use this script requires Python Version 2.X 32 bit version. On Windows, we recommend downloading ActiveState's ActivePython for Windows (Version 2.X NOT 3.X (32bit).
We strongly recommend that at the moment people with Kindle for Windows should use K4PCDeDRM.pyw instead of any of the other methods (skindle, unswindle).
K4PCDeDRM is available in the large archive mentioned in the first post.
To run it simply completely extract the tools archive and open the Kindle_4_PC_Tools. Then double-click on K4PCDeDRM.pyw to run the gui version.
Please note, the tools archive must be on the same machine in the same account as the Kindle for PC application for things to work.
FYI:
Books downloaded to Kindle for PC are stored in a folder called “My Kindle Content” in the current user’s home folder.
IMPORTANT: There are two kinds of Kindle ebooks. Mobipocket and Topaz. For Topaz books it’s really necessary to use the Topaz specific tools mentioned in this post which not only remove the DRM but also convert the Topaz file into a format that can be converted into other formats.

#!/usr/bin/env python

# This is a WINDOWS python script. You need a Python interpreter to run it.
# For example, ActiveState Python, which exists for windows.
#
# It can run standalone to convert K4PC files, or it can be installed as a
# plugin for Calibre (http://calibre-ebook.com/about) so that importing
# K4PC files with DRM is no londer a multi-step process.
#
# ***NOTE*** Calibre and K4PC must be installed on the same windows machine
# 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 and import that ZIP into Calibre
# using its plugin configuration GUI.
#
# Thanks to The Dark Reverser for MobiDeDrm and CMBDTC for cmbdtc_dump from
# which this script steals most unashamedly.
#
# Changelog
# 0.01 - Initial version - Utilizes skindle and CMBDTC method of obtaining
# book specific pids from K4PC books. If Calibre and K4PC are installed
# on the same windows machine, Calibre plugin functionality is once
# again restored.

K4MobiDeDRM
This tools combines functionality of MobiDeDRM with that of K4PCDeDRM, K4MDeDRM, and K4DeDRM. Effectively, it provides one-stop shopping for all your Mobipocket, Kindle for iPhone/iPad/iPodTouch, Kindle for PC, and Kindle for Mac needs.
****
Please Note: If you a happy user of MobiDeDRM, K4DeDRM, K4PCDeDRM, or K4MUnswindle, please continue to use these programs as there is no additional capability provided by this tool over the others. In the long run, if you have problems with any of those tools, you might want to try this one as it will continue under development eventually replacing all of those tools.
****
1. double-click on K4MobiDeDRM.pyw
2. In the window that opens:
hit the first '...' button to locate your DRM Kindle-style ebook
3. Then hit the second '...' button to select an output directory for the unlocked file
4. Then add in any PIDs you need from KindleV1, Kindle for iPhone/iPad/iPodTouch, or other single PID devices to the provided box as a comma separated list of 10 digit PID numbers.
If this is a Kindle for Mac or a Kindle for PC book then you can leave this box blank
5. hit the 'Start' button
After a short delay, you should see progress in the Conversion Log window indicating is the unlocking was a success or failure.

# 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.

README
unswindle can be used to find the book specific PID but it needs to be updated for each version of Kindle4PC that Amazon releases (and therefore is also useful for Linux users who have Wine). This program “patches” the Kindle4PC executable and therefore is very release specific.
Unfortunately unswindle v7 the latest, has not been updated to work with the latest version of Kindle for PC. You will need to find one of the older versions of Kindle4PC and prevent later updates in order to use this tool.

- MobiDeDRM.pyw is a simple graphical front end to the mobidedrm.py progam that actually does the DRM removal as long as you know the correct PID to use with it (which depends on the versions of Kindle software used). This is a gui program, simply double-click to launch it.
PIDCHeck.py is a command line python tools to take an 8 digit PID and add the 2 checksum digits to the end to generate a 10 digit PID
All of these scripts are python programs. Python 2.X (32 bit) is already installed in Mac OSX and Linux. We recommend ActiveState's Active Python Version 2.X (32 bit) for Windows users.

Kindle Mobipocket tools 0.2
Copyright (c) 2007, 2009 Igor Skochinsky <skochinsky@mail.ru>
These scripts allow one to read legally purchased Secure Mobipocket books
on Amazon Kindle or Kindle for iPhone.
* kindlepid.py
This script generates Mobipocket PID from the Kindle serial number or iPhone/iPod Touch
identifier (UDID). That PID can then be added at a Mobi retailer site and used for downloading
books locked to the Kindle.
Example:
> kindlepid.py B001BAB012345678
Mobipocket PID calculator for Amazon Kindle. Copyright (c) 2007, 2009 Igor Skochinsky
Kindle 1 serial number detected
Mobipocked PID for Kindle serial# B001BAB012345678 is V176CXM*FZ
* kindlefix.py
This script adds a "CustomDRM" flag necessary for opening Secure
Mobipocket books on Kindle. The book has to be enabled for Kindle's PID
(generated by kindlepid.py). The "fixed" book is written with
extension ".azw". That file can then be uploaded to Kindle for reading.
Example:
> kindlefix.py MyBook.mobi V176CXM*FZ
The Kindleizer v0.2. Copyright (c) 2007, 2009 Igor Skochinsky
Encryption: 2
Mobi publication type: 2
Mobi format version: 4
Found the matching record; setting the CustomDRM flag for Kindle
Output written to MyBook.azw
* History
2007-12-12 Initial release
2009-03-10 Updated scripts to version 0.2
kindlepid.py: Added support for generating PID for iPhone (thanks to mbp)
kindlefix.py: Fixed corrupted metadata issue (thanks to Mark Peek)

#!/usr/bin/python
#
# This is a python script. You need a Python interpreter to run it.
# For example, ActiveState Python, which exists for windows.
#
# It can run standalone to convert files, or it can be installed as a
# plugin for Calibre (http://calibre-ebook.com/about) so that
# importing files with DRM 'Just Works'.
#
# To create a Calibre plugin, rename this file so that the filename
# ends in '_plugin.py', put it into a ZIP file and import that Calibre
# using its plugin configuration GUI.
#
# Changelog
# 0.01 - Initial version
# 0.02 - Huffdic compressed books were not properly decrypted
# 0.03 - Wasn't checking MOBI header length
# 0.04 - Wasn't sanity checking size of data record
# 0.05 - It seems that the extra data flags take two bytes not four
# 0.06 - And that low bit does mean something after all :-)
# 0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
# 0.08 - ...and also not in Mobi header version < 6
# 0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
# 0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
# import filter it works when importing unencrypted files.
# Also now handles encrypted files that don't need a specific PID.
# 0.11 - use autoflushed stdout and proper return values
# 0.12 - Fix for problems with metadata import as Calibre plugin, report errors
# 0.13 - Formatting fixes: retabbed file, removed trailing whitespace
# and extra blank lines, converted CR/LF pairs at ends of each line,
# and other cosmetic fixes.
# 0.14 - Working out when the extra data flags are present has been problematic
# Versions 7 through 9 have tried to tweak the conditions, but have been
# only partially successful. Closer examination of lots of sample
# files reveals that a confusin has arisen because trailing data entries
# are not encrypted, but it turns out that the multibyte entries
# in utf8 file are encrypted. (Although neither kind gets compressed.)
# This knowledge leads to a simplification of the test for the
# trailing data byte flags - version 5 and higher AND header size >= 0xE4.
# 0.15 - Now outputs 'hearbeat', and is also quicker for long files.
# 0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.
# 0.17 - added modifications to support its use as an imported python module
# both inside calibre and also in other places (ie K4DeDRM tools)
# 0.17a - disabled the standalone plugin feature since a plugin can not import
# a plugin
