Usage

From source file:edu.osu.ling.pep.Pep.java

/**
 * Invokes Pep from the command line.//ww  w .  j a va2  s.  c  o  m
 * <p>
 * The main work this method does, apart from tokenizing the arguments and
 * input tokens, is to load and parse the XML grammar file (as specified by
 * <code>-g</code> or <code>--grammar</code>). If any of the arguments
 * <code>-g</code>, <code>--grammar</code>, <code>-s</code>,
 * <code>--seed</code>, <code>-o</code>, <code>--option</code>, occur with
 * no argument following, this method prints an error notifying the user.
 * 
 * @param args
 *            The expected arguments are as follows, and can occur in any
 *            particular order:
 *            <ul>
 *            <li><code>-g|--grammar &lt;grammar file&gt;</code></li> <li>
 *            <code>-s|--seed &lt;seed category&gt;</code></li> <li><code>
 *            -v|--verbose {verbosity level}</code></li> <li><code>
 *            -o|--option &lt;OPTION_NAME=value&gt;</code></li> <li><code>
 *            -h|--help (prints usage information)</code></li> <li><code>
 *            &lt;token1 ... token<em>n</em>&gt;</code> (or <code>-</code>
 *            for standard input)</li>
 *            </ul>
 *            <code>OPTION_NAME</code> must be the name of one of the
 *            recognized {@link ParserOption options}. If <code>-h</code> or
 *            <code>--help</code> occur anywhere in the arguments, usage
 *            information is printed and no parsing takes place.
