<h2><a name="About_Apache_Rat8482"></a>About Apache Rat&#8482;</h2>
<p>Rat audits software distributions, with a special interest in headers. If this isn't quite what you're looking for then take a look at the other products developed by <a class="externalLink" href="http://creadur.apache.org">Apache Creadur</a>&#8482;, including <a class="externalLink" href="http://creadur.apache.org/whisker">Apache Whisker</a>&#8482; which audits and generates legal (for example <tt>LICENSE</tt>) documents for complex software distributions.</p>
<div class="section">
<h3><a name="Running_from_the_Command_Line"></a>Running from the Command Line</h3>
<p>Run from the command line with:</p>
<div class="source">
<pre>java -jar apache-rat-0.13-SNAPSHOT.jar --help</pre></div>
<p>This will output a help message detailing the command line options available to you.</p></div>
<div class="section">
<h3><a name="Adding_license_headers"></a>Adding license headers</h3>
<p>Rat can be used to automatically add license headers to files that do not currently have them. Only files that are not excluded by the Rat configurations will be affected.</p>
<p>To add license headers use a command such as:</p>
<div class="source">
<pre>java -jar apache-rat-0.13-SNAPSHOT.jar --addlicense
--copyright &quot;Copyright 2008 Foo&quot; --force
/path/to/project</pre></div>
<p>This command will add the license header directly to the source files. If you prefer to see which files will be changed and how then remove the &quot;--force&quot; option.</p></div>
<div class="section">
<h3><a name="Using_multiple_excludes_from_a_file"></a>Using multiple excludes from a file</h3>
<p>It is common to use the Rat with the Maven or Ant plugins and specify a series of files to exclude (such as a README or version control files). If you are using the Rat application instead of a plugin you can specify a series of regex excludes in a file and specify that with the -E option.</p>
<div class="source">
<pre>java -jar apache-rat-0.13-SNAPSHOT.jar
-E /path/to/project/.rat-excludes
-d /path/to/project</pre></div></div>
<div class="section">
<h3><a name="Command_Line_Options"></a>Command Line Options</h3>
<div class="source">
