-Introduction
-------------
-
-libgourou is a free implementation of Adobe's ADEPT protocol used to add DRM on ePub/PDF files. It overcome the lacks of Adobe support for Linux platforms.

-Dependencies
-------------
-
-For libgourou :
-
-  * None
-
-For utils :
-
-  * QT5Core
-  * QT5Network
-  * OpenSSL
-  * libzip

-You can import configuration from your eReader or create a new one with utils/activate :
-
-    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD
-    ./activate -u <AdobeID USERNAME>
-
-Then a _./.adept_ directory is created with all configuration file
