#    Description: This Bash script automates the steps to resign your Nook®
#                 files that were previously signed with B&N keys in order
#                 to allow system apps modifications.
#                 The script can also optionally patch ReaderRMSDK in order
#                 to use external apk file and convert original dictionaries.
#                 ReaderRMSDK modification as well as Lookup application was
#                 developed by RenateRST from XDA forum
#                 ( http://forum.xda-developers.com/member.php?u=4474482,
#                 http://www.temblast.com/ ): I would like to specially
#                 thank her for her work as well as user 'ApokrifX' from XDA
#                 ( http://forum.xda-developers.com/member.php?u=4107074 )
#                 for his help in OpenSSL understanding.
