Howeverfor large packages this is inconvenient and it is better to split theraw configuration data over several different files. The <SPANCLASS="PROPERTY">script</SPAN>property can be used to achieve this. It takes a single filename asargument. If the package follows the <AHREF="package.html#PACKAGE.HIERARCHY">directory layout conventions</A> thenthe configuration tools will look for the specified file in the<TTCLASS="FILENAME">cdl</TT> sub-directory of thepackage, otherwise it will look for the file relative to the package'stop-level directory.</P><P>The <SPANCLASS="PROPERTY">script</SPAN> property can only occur in the body of a <TTCLASS="LITERAL">cdl_component</TT>command, and only one <SPANCLASS="PROPERTY">script</SPAN> property per body is allowed.</P></DIV><DIVCLASS="REFSECT1"><ANAME="AEN4971"></A><H2>Example</H2><TABLEBORDER="5"BGCOLOR="#E0E0F0"WIDTH="70%"><TR><TD><PRECLASS="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.
