+/**
+ * RepQuoteExample is a simple but complete demonstration of a replicated
+ * application. The application is a mock stock ticker. The master accepts a
+ * stock symbol and an numerical value as input, and stores this information
+ * into a replicated database; either master or clients can display the
+ * contents of the database.
+ * <p>
+ * The options to start a given replication node are:
+ * <pre>
+ * -h home (required; h stands for home directory)
+ * -l host:port (required; l stands for local)
+ * -C or M (optional; start up as client or master)
+ * -r host:port (optional; r stands for remote; any number of these may
+ * be specified)
+ * -R host:port (optional; R stands for remote peer; only one of these may
+ * be specified)
+ * -a all|quorum (optional; a stands for ack policy)
+ * -b (optional; b stands for bulk)
+ * -n nsites (optional; number of sites in replication group; defaults to 0
+ * to try to dynamically compute nsites)
+ * -p priority (optional; defaults to 100)
+ * -v (optional; v stands for verbose)
+ * </pre>
+ * <p>
+ * A typical session begins with a command such as the following to start a
+ * master:
+ *
+ * <pre>
+ * java db.repquote.RepQuoteExample -M -h dir1 -l localhost:6000
+ * </pre>
+ *
+ * and several clients:
+ *
+ * <pre>
+ * java db.repquote.RepQuoteExample -C -h dir2
+ * -l localhost:6001 -r localhost:6000
+ * java db.repquote.RepQuoteExample -C -h dir3
+ * -l localhost:6002 -r localhost:6000
+ * java db.repquote.RepQuoteExample -C -h dir4
+ * -l localhost:6003 -r localhost:6000
+ * </pre>
+ *
+ * <p>
+ * Each process is a member of a DB replication group. The sample application
+ * expects the following commands to stdin:
+ * <ul>
+ * <li>NEWLINE -- print all the stocks held in the database</li>
+ * <li>quit -- shutdown this node</li>
+ * <li>exit -- shutdown this node</li>
+ * <li>stock_symbol number -- enter this stock and number into the
+ * database</li>
+ * </ul>
