+# == 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.
+# --base-date::
+# a base time point for this calicuration (default now). Ex. '2009-10-31'
+#
+# --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
+#
