+EXAMPLES
+
+        1. % ./shogi-server test 4081
+           Run the shogi-server. Then clients can connect to port#4081.
+           The server output logs to the stdout.
+
+        2. % ./shogi-server --daemon . --pid-file ./shogi-server.pid \
+                            --player-log-dir ./player-logs \
+                            test 4081
+           Run the shogi-server as a daemon. The server outputs regular logs
+           to shogi-server.log located in the current directory and network 
+           messages in ./player-logs directory.
+
+        3. % ./shogi-server --daemon . --pid-file ./shogi-server.pid \
+                            --player-log-dir ./player-logs \
+                            --floodgate-games floodgate-900-0,floodgate-3600-0 \
+                            test 4081
+           Run the shogi-server with two groups of Floodgate games.
+           Configuration files allow you to schedule starting times. Consult  
+           floodgate-0-240.conf.sample or shogi_server/league/floodgate.rb 
+           for format details.
+
+FLOODGATE SCHEDULE CONFIGURATIONS
+
+           You need to set starting times of floodgate groups in
+           configuration files under the top directory. Each floodgate 
+            group requires a corresponding configuration file named
+           "<game_name>.conf". The file will be re-read once just after a
+           game starts. 
+           
+           For example, a floodgate-3600-30 game group requires
+           floodgate-3600-30.conf.  However, for floodgate-900-0 and
+           floodgate-3600-0, which were default enabled in previous
+           versions, configuration files are optional if you are happy with
+           default time settings.
+           File format is:
+             Line format: 
+               # This is a comment line
+               DoW Time
+               ...
+             where
+               DoW := "Sun" | "Mon" | "Tue" | "Wed" | "Thu" | "Fri" | "Sat" |
+                      "Sunday" | "Monday" | "Tuesday" | "Wednesday" | "Thursday" |
+                      "Friday" | "Saturday" 
+               Time := HH:MM
+            
+             For example,
+               Sat 13:00
+               Sat 22:00
+               Sun 13:00
+
+            PAREMETER SETTING
+
+            In addition, this configuration file allows to set parameters
+            for the specific Floodaget group. A list of parameters is the
+            following:
+
+            * pairing_factory:
+              Specifies a factory function name generating a pairing
+              method which will be used in a specific Floodgate game.
+              ex. set pairing_factory floodgate_zyunisen
+            * sacrifice:
+              Specifies a sacrificed player.
+              ex. set sacrifice gps500+e293220e3f8a3e59f79f6b0efffaa931
