+/**
+ * @mainpage PolarSSL v0.14.0 source code documentation
+ * 
+ * This documentation describes the internal structure of PolarSSL.  It was
+ * automatically generated from specially formatted comment blocks in
+ * PolarSSL's source code using Doxygen.  (See
+ * http://www.stack.nl/~dimitri/doxygen/ for more information on Doxygen)
+ * 
+ * PolarSSL has a simple setup: it provides the ingredients for an SSL/TLS 
+ * implementation. These ingredients are listed as modules in the 
+ * \ref mainpage_modules "Modules section". This "Modules section" introduces 
+ * the high-level module concepts used throughout this documentation.\n 
+ * Some examples of PolarSSL usage can be found in the \ref mainpage_examples
+ * "Examples section".
+ * 
+ * 
+ * @section mainpage_modules Modules
+ * 
+ * PolarSSL supports SSLv3 up to TLSv1.1 communication by providing the 
+ * following:
+ * - TCP/IP communication functions: listen, connect, accept, read/write.
+ * - SSL/TLS communication functions: init, handshake, read/write.
+ * - X.509 functions: CRT, CRL and key handling
+ * - Random number generation
+ * - Hashing
+ * - Encryption/decryption
+ *
+ * Above functions are split up neatly into logical interfaces. These can be 
+ * used separately to provide any of the above functions or to mix-and-match 
+ * into an SSL server/client solution that utilises a X.509 PKI. Examples of 
+ * such implementations are amply provided with the source code. Note that 
+ * there is also an OpenSSL wrapper provided.\n
+ * Note that PolarSSL does not provide a control channel or (multiple) session
+ * handling. 
+ *
+ * @section mainpage_examples Examples
+ * 
+ * Example server setup:
+ *
+ * \b Prerequisites: 
+ * - X.509 certificate and private key
+ * - session handling functions
+ *
+ * \b Setup:
+ * - Load your certificate and your private RSA key (X.509 interface)
+ * - Setup the listening TCP socket (TCP/IP interface)
+ * - Accept incoming client connection (TCP/IP interface)
+ * - Initialise as an SSL-server (SSL/TLS interface)
+ *   - Set parameters, e.g. authentication, ciphers, CA-chain, key exchange
+ *   - Set callback functions RNG, IO, session handling
+ * - Perform an SSL-handshake (SSL/TLS interface)
+ * - Read/write data (SSL/TLS interface)
+ * - Close and cleanup (all interfaces)
+ *
+ *
+ * Example client setup:
+ *
+ * \b Prerequisites:
+ * - X.509 certificate and private key
+ * - X.509 trusted CA certificates
+ *
+ * \b Setup:
+ * - Load the trusted CA certificates (X.509 interface)
+ * - Load your certificate and your private RSA key (X.509 interface)
+ * - Setup a TCP/IP connection (TCP/IP interface)
+ * - Initialise as an SSL-client (SSL/TLS interface)
+ *   - Set parameters, e.g. authentication mode, ciphers, CA-chain, session
+ *   - Set callback functions RNG, IO
+ * - Perform an SSL-handshake (SSL/TLS interface)
+ * - Verify the server certificate (SSL/TLS interface)
+ * - Write/read data (SSL/TLS interface)
+ * - Close and cleanup (all interfaces)
