 <h2>Creating your own DUNE project module</h2>
-<ol>
 <p>
 You can create your own dune project module by using the duneproject script available in dune-common/bin directory.
 Running the script will create a directory with supporting files (configure.ac ,Makefile.am etc.) and a sample .cc file.
 After creating the module you can build this as explained above under "Building a specific DUNE module".
