    <target name="getlatestversionvss">
        <vssget databasepath="c:\vss\astronom_vss" 
            path="$/astronom_vss" 
            localpath="c:\visualstudiosource\astronomysolution\astronom" username="build" password="build" />
    </target>
    <target name="compile" dependsontargets="getlatestversionvss">
