libdvdcss is a simple library designed for accessing DVDs like a block device
without having to bother about the decryption. The important features are:

- Portability :: Currently supported platforms are GNU/Linux, FreeBSD, NetBSD,
  OpenBSD, Haiku, Mac OS X, Solaris, QNX, OS/2, and Windows.
- Simplicity :: A DVD player can be built around the libdvdcss API using no more
  than 4 or 5 library calls.
- Freedom :: libdvdcss is released under the General Public License, ensuring it
  will stay free, and used only for Free Software products.
- Just better :: Unlike most similar projects, libdvdcss does not require the
  region of your drive to be set.
