<h3>
The Interpreter</h3>
<p>The JPython installation places several files on your system, including a set of modules, some sample programs, an application called <tT CLAss="monofont">jpythonc</tt> (which we will see later), and the JPython interpreter.</P>
<P>The JPython interpreter looks very similar to the CPython interpreter (see <A Href="246#1.html">Figure 18.2</a>). However, <TT CLass="monofont">jpython</tt> is not a binary file, but a short script (or batch file, depending on your system) that invokes your local JVM, sets the Java property <tt class="monofont">install.path</tt> to an appropriate value, and then runs the Java class file <tt clasS="monofont">org.python.util.jpython.</tt>
</P>

<h5>
<a Name="1"></A>Figure 18.2. If you glance at this screen, you might be confused whether JPython or CPython is running because both interpreters do look alike.</H5>

<p>The following syntax shows the possible options that you can pass to JPython when invoking it from the shell. A list of options is shown in <a href="246#2.html">Table 18.1</a>.</p>

jpython [options] [-jar jar | -c cmd | file | -] [args]
