+# == Synopsis
+#
+# mk_rate reads CSA files, calculates rating scores of each player, and then
+# outputs a yaml file (players.yaml) that Shogi-server can recognize.
 #
+# == Usage
 #
-# PREREQUIRE
-# ==========
+# ./mk_rate [options] DIR..
+# 
+# DIR::
+#   CSA files are recursively looked up the directories.
 #
-# Sample Commands to isntall prerequires will work for Debian.
+# --half-life::
+#   n [days] (default 60)
+#   
+# --half-life-ignore::
+#   m [days] (default  7)
+#   after m days, the half-life effect works
+#
+# --fixed-rate-player::
+#   player whose rate is fixed at the rate
+#
+# --fixed-rate::
+#   rate 
+#
+# --help::
+#   show this message
