    <h1>MySQL/Ruby</h1>
    <p><a href="README_ja.html">[Japanese]</a></p>
    <hr>
    <p>
      This is the <a href="http://www.mysql.com">MySQL</a> API module for Ruby.
      It provides the same functions for Ruby programs that the MySQL C API provides for C programs.
    </p>

    <h2>Download</h2>
    <ul>
      <li><a href="http://rubyforge.org/frs/?group_id=4550">RubyForge</a>
      <li><a href="http://tmtm.org/downloads/mysql/ruby/">tmtm.org</a>
    </ul>

    <h2>Requirement</h2>
    <ul>
      <li>MySQL 5.0.67
      <li>Ruby 1.8.7, 1.9.1
    </ul>
    <p>
      The module may work for other versions, but that has not been verified.
    </p>

    <h2>License</h2>
    <p>
      This program is under <a href="http://www.ruby-lang.org/en/LICENSE.txt">Ruby's license</a>.
    </p>

    <h2>Install</h2>
    <p>
      1st:
    </p>
    <pre class="code">
% ruby extconf.rb
</pre>
    <p>
      or
    </p>
    <pre class="code">
% ruby extconf.rb --with-mysql-dir=/usr/local/mysql
</pre>
    <p>
      or
    </p>
    <pre clas="code">
% ruby extconf.rb --with-mysql-config
</pre>
    <p>
      then
    </p>
    <pre>
% make
</pre>
    <p>
      extconf.rb has following options:
    </p>
    <dl>
      <dt>--with-mysql-include=<i>dir</i>
      <dd>
	MySQL header file directory. Default is /usr/local/include.

      <dt>--with-mysql-lib=<i>dir</i>
      <dd>
	MySQL library directory. Default is /usr/local/lib.

      <dt>--with-mysql-dir=<i>dir</i>
      <dd>
	Same as --with-mysql-include=<i>dir</i>/include,
	--with-mysql-lib=<i>dir</i>/lib.

      <dt>--with-mysql-config[=<i>/path/to/mysql_config</i>]
      <dd>
	Get compile-parameter from mysql_config command.
    </dl>
    <p>
      2nd:
    </p>
    <pre class="code">
% ruby ./test.rb -- [<i>hostname</i> [<i>user</i> [<i>passwd</i> [<i>dbname</i> [<i>port</i> [<i>socket</i> [<i>flag</i>]]]]]]]
</pre>

    <p>
      3rd:
    </p>
    <pre class="code">
# make install
</pre>

    <h3>Note</h3>
    <p>
      If you get error like 'libmysqlclient not found' when testing,
      you need to specify the directory in which the library is
      located so that make can find it.
    </p>
    <pre class="code">
% env LD_RUN_PATH=<i>libmysqlclient.so directory</i> make
</pre>
    <p>
      test.rb is tested on Linux only.
    </p>

    <h2>Usage</h2>
    <p>
      The names of methods provided by this module basically are the
      same as the names of the functions in the C API, except that the
      Ruby method names do not begin with a 'mysql_' prefix. For
      example, the Ruby query() method corresponds to the C API
      mysql_query() function. For details on the use of each Ruby
      method, see the descriptions of the corresponding C functions in
      the MySQL Reference Manual.
    </p>
    <p>
      Some Ruby methods may be invoked under other names that serve as
      equivalent aliases, as noted below.
    </p>
    <p>
      If an error occurs when a method executes, it raises a
      Mysql::Error exception.
    </p>
