                subant can be used with directory sets to execute a build from different directories.
                2 different options are offered :
            </p>
<ul>
                <li>
                    to run the same build file <code>/somepath/otherpath/mybuild.xml</code>
                    with different base directories, use the genericantfile attribute
                </li>
                <li>if you want to run <code>directory1/mybuild.xml</code>, <code>directory2/mybuild.xml</code>, <code>....</code>,
                    use the antfile attribute. The subant task does not set the base directory for you in this case.<br/>                    because you can specify it in each build file.
