However for large packages this is inconvenient and it is better to split the raw configuration data over several different files. The <SPAN CLASS="PROPERTY" >script</SPAN > property can be used to achieve this. It takes a single filename as argument. If the package follows the <A HREF="package.html#PACKAGE.HIERARCHY" >directory layout conventions</A > then the configuration tools will look for the specified file in the <TT CLASS="FILENAME" >cdl</TT > sub-directory of the package, otherwise it will look for the file relative to the package's top-level directory.</P ><P >The <SPAN CLASS="PROPERTY" >script</SPAN > property can only occur in the body of a <TT CLASS="LITERAL" >cdl_component</TT >command, and only one <SPAN CLASS="PROPERTY" >script</SPAN > property per body is allowed.</P ></DIV ><DIV CLASS="REFSECT1" ><A NAME="AEN4971" ></A ><H2 >Example</H2 ><TABLE BORDER="5" BGCOLOR="#E0E0F0" WIDTH="70%" ><TR ><TD ><PRE CLASS="PROGRAMLISTING" >cdl_component CYGPKG_UITRON_TASKS { display "Tasks" flavor none description " uITRON Tasks are the basic blocks of multi-tasking in the uITRON world; they are threads or lightweight processes, sharing the address space and the CPU.
