+ * the aim of this demo is to provide a fully working state-machine
+ * style SSL implementation, i.e. one where the main loop acquires
+ * some data, then converts it from or to SSL by feeding it into the
+ * SSL state machine. It then does any I/O required by the state machine
+ * and loops.
+ *
+ * In order to keep things as simple as possible, this implementation
+ * listens on a TCP socket, which it expects to get an SSL connection
+ * on (for example, from s_client) and from then on writes decrypted
+ * data to stdout and encrypts anything arriving on stdin. Verbose
+ * commentary is written to stderr.
+ *
+ * This implementation acts as a server, but it can also be done for a client.  */
