ant buildfile

I am not too familiar with ant, but today I successfully managed to modify someone's ant buildfile to see my  very own files:

The original file had this:

<path id="compile.classpath">
                <fileset dir="${lib}">
                        <include name="weka.jar"/>
                        <include name="postaipc-0.8.5.jar"/>
                        <include name="clipc-0.2.jar"/>
                </fileset>
        </path>

and I simply modified it to:

<path id="compile.classpath">
                <fileset dir="${lib}">
                        <include name="weka.jar"/>
                        <include name="postaipc-0.8.5.jar"/>
                        <include name="clipc-0.2.jar"/>
                </fileset>
                <pathelement location="/home/me/myfiles"/>
        </path>
