#
# == 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.
+# mk_rate reads game results files generated by the mk_game_results command,
+# calculates rating scores of each player, and then outputs a yaml file
+# (players.yaml) that Shogi-server can recognize.
#
# == Usage
#
-# ./mk_rate [options] DIR..
+# ./mk_rate [options] GAME_RESULTS_FILE [...]
+#
+# ./mk_rate [options]
#
-# DIR::
-# CSA files are recursively looked up the directories.
+# GAME_RESULTS_FILE::
+# a path to a file listing results of games, which is genrated by the
+# mk_game_results command.
+# In the second style above, the file content can be read from the stdin.
#
# --base-date::
# a base time point for this calicuration (default now). Ex. '2009-10-31'
# m [days] (default 7)
# after m days, the half-life effect works
#
+# --ignore::
+# m [days] (default 365*2)
+# old results will be ignored
+#
# --fixed-rate-player::
# player whose rate is fixed at the rate
#
# --fixed-rate::
# rate
#
+# --skip-draw-games::
+# skip draw games. [default: draw games are counted in as 0.5 win and 0.5
+# lost.]
