+/**
+ * \mainpage libdvdcss developer documentation
+ *
+ * \section intro Introduction
+ *
+ * \e libdvdcss is a simple library designed for accessing DVDs like a block
+ * device without having to bother about the decryption. The important features
+ * are:
+ * \li portability: currently supported platforms are GNU/Linux, FreeBSD,
+ * NetBSD, OpenBSD, BSD/OS, BeOS, Windows 95/98, Windows NT/2000, MacOS X,
+ * Solaris, HP-UX and OS/2.
+ * \li adaptability: unlike most similar projects, libdvdcss doesn't require
+ * the region of your drive to be set and will try its best to read from
+ * the disc even in the case of a region mismatch.
+ * \li simplicity: a DVD player can be built around the \e libdvdcss API using
+ * no more than 4 or 5 library calls.
+ *
+ * \e libdvdcss is free software, released under the General Public License.
+ * This ensures that \e libdvdcss remains free and used only with free
+ * software.
+ *
+ * \section api The libdvdcss API
+ *
+ * The complete \e libdvdcss programming interface is documented in the
+ * dvdcss.h file.
+ *
+ * \section env Environment variables
+ *
+ * Some environment variables can be used to change the behaviour of
+ * \e libdvdcss without having to modify the program which uses it. These
+ * variables are:
+ *
+ * \li \b DVDCSS_VERBOSE: sets the verbosity level.
+ * - \c 0 outputs no messages at all.
+ * - \c 1 outputs error messages to stderr.
+ * - \c 2 outputs error messages and debug messages to stderr.
+ *
+ * \li \b DVDCSS_METHOD: sets the authentication and decryption method
+ * that \e libdvdcss will use to read scrambled discs. Can be one
+ * of \c title, \c key or \c disc.
+ * - \c key is the default method. \e libdvdcss will use a set of
+ * calculated player keys to try and get the disc key. This can fail
+ * if the drive does not recognize any of the player keys.
+ * - \c disc is a fallback method when \c key has failed. Instead of
+ * using player keys, \e libdvdcss will crack the disc key using
+ * a brute force algorithm. This process is CPU intensive and requires
+ * 64 MB of memory to store temporary data.
+ * - \c title is the fallback when all other methods have failed. It does
+ * not rely on a key exchange with the DVD drive, but rather uses a
+ * crypto attack to guess the title key. On rare cases this may fail
+ * because there is not enough encrypted data on the disc to perform
+ * a statistical attack, but in the other hand it is the only way to
+ * decrypt a DVD stored on a hard disc, or a DVD with the wrong region
+ * on an RPC2 drive.
+ *
+ * \li \b DVDCSS_RAW_DEVICE: specify the raw device to use.
+ *
