        First release

0.02    2010/04/18 [API Changed]
        If you specify an absolute path to the connection info file
        as "config_file", "config_base" is now always ignored, since
        this is more intuitive behaviour.

0.03    2010/04/24 [New Feature] [API Changed]
        You can now invoke "get_dbh" method just like DBI::connect.
        Thus, you have to specify "dsn" in connection info file,
        with the prefix of "dbi:".

        Fixed a small defection that warns when passing an odd number
        of elements to get_dbh method during object construction.
