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

It's the first tool for free systems to be able to read Adobe DRM
protected ebooks (the industry standard for purchases and library
loans), and add them to your ereader.

It permits:

- Downloading an ePub/PDF from ACSM file
- Exporting your private key (for DeDRM software)
- Removing ADEPT DRM
- List loaned books
- Return a loaned book

I have written a debian packaging for libgourou, using debian's
packaging tools, that may be useful as a basis for an official package.

Please feel free to take this packaging whole or partial or whatever, if
it can be used to create an official debian package.
