relative paths

[Derek A. Bodin]

When using the path element ant automatically converts the path to a
direct path, is there any way to keep the path relative?  I am trying to
do this for the class-path element of the manifest file so that I can
move an application to another computer and have it work there also,
thanks.
 
<path id="class.path">
            <fileset dir="src/lib">
                        <include name="**/*.jar"/>
            </fileset>
 </path>
