<p>Outputs a list of all the source files that are required by the
specified <code class="docutils literal notranslate"><span class="pre">srcfile</span></code>. This list is written into <code class="docutils literal notranslate"><span class="pre">outputfile</span></code>. This is
similar to writing out the dependencies for <code class="docutils literal notranslate"><span class="pre">srcfile</span></code> except that it
jumps from <code class="docutils literal notranslate"><span class="pre">.h</span></code> files into <code class="docutils literal notranslate"><span class="pre">.cxx</span></code>, <code class="docutils literal notranslate"><span class="pre">.c</span></code> and <code class="docutils literal notranslate"><span class="pre">.cpp</span></code> files if possible.</p>
