+o -f option
+
+  This supports for reading transaction script from a specified
+  file. This file should include SQL commands in each line. SQL
+  command consists of multiple lines are not supported. Empty lines
+  and lines begging with "--" will be ignored.
+
+  SQL commands can include "meta command" which begins with "\" (back
+  slash). A meta command takes some arguments separted by white
+  spaces. Currently following meta command is supported:
+
+  \setrandom name min max
+
+	assign random integer to name between min and max
+
+  example:
+
+  \setrandom aid 1 100000
+
+  variables can be reffered to in SQL comands by adding ":" in front
+  of the varible name.
+
+  example:
+
+  SELECT abalance FROM accounts WHERE aid = :aid
+
+  For example, TPC-B like benchmark can be defined as follows(scaling
+  factor = 1):
+
+\setrandom aid 1 100000
+\setrandom bid 1 1
+\setrandom tid 1 10
+\setrandom delta 1 10000
+BEGIN
+UPDATE accounts SET abalance = abalance + :delta WHERE aid = :aid
+SELECT abalance FROM accounts WHERE aid = :aid
+UPDATE tellers SET tbalance = tbalance + :delta WHERE tid = :tid
+UPDATE branches SET bbalance = bbalance + :delta WHERE bid = :bid
+INSERT INTO history (tid, bid, aid, delta, mtime) VALUES (:tid, :bid, :aid, :delta, 'now')
