<h2>DESCRIPTION<a class="headerlink" href="#description" title="Permalink to this headline">¶</a></h2>
<p>Auto dependency (autodep) builder is a tool for the analysis of accessed files during
the build of a package. It also can be used for runtime dependencies analysis.</p>
<p>The tool can trace, log and block access to files of given packages.</p>
