The model that should be kept in mind, is that the newly created functor employs an internal, private module manager that excutes the toplevel application functor together with all included functors. </P><P> A short introduction by means of examples can be found in <A href="../apptut/node7.html#section.deployment.linking">Section 6.1 of ``Application Programming''</A>. </P><HR><UL class="toc"><LI><A href="node8.html#section.linker.basic">3.1 Basic Usage</A></LI></UL><UL class="toc"><LI><A href="node9.html#section.linker.include">3.2 Including and Excluding Functors</A></LI></UL><UL class="toc"><LI><A href="node10.html#section.linker.pickling">3.3 Pickling Options</A></LI></UL><UL class="toc"><LI><A href="node11.html#section.linker.misc">3.4 Miscellaneous Options</A></LI></UL></DIV><TABLE align="center" border="0" cellpadding="6" cellspacing="6" class="nav"><TR bgcolor="#DDDDDD"><TD><A href="node2.html#chapter.compiler"><< Prev</A></TD><TD><A href="index.html">- Up -</A></TD><TD><A href="node12.html#chapter.debugger">Next >></A></TD></TR></TABLE><HR><ADDRESS><A href="http://www.ps.uni-sb.de/~duchier/">Denys Duchier</A>, <A href="http://www.ps.uni-sb.de/~kornstae/">Leif Kornstaedt</A> and <A href="http://www.ps.uni-sb.de/~schulte/">Christian Schulte</A><BR><SPAN class="version">Version 1.4.0 (20090610)</SPAN></ADDRESS></BODY></HTML>
