12The CBC distribution includes a number of <tt class="filename">.cpp</tt> sample files.
13Users are encouraged to use them as starting points for their own CBC projects.
14The files can be found in the <tt class="filename">COIN/Cbc/Samples/</tt> directory.
15For the latest information on compiling and running these samples, please see
16the file <tt class="filename">COIN/Cbc/Samples/INSTALL</tt>.  Most of them can be built
17by </p><pre class="programlisting">make DRIVER=name</pre><p> which produces an executable testit.  Below is a list of
18some of the most useful sample files with a short description for each file.
