+Factory class that Rhino runtime uses to create new <A HREF="../../../org/mozilla/javascript/Context.html" title="class in org.mozilla.javascript"><CODE>Context</CODE></A>
+ instances. A <code>ContextFactory</code> can also notify listeners
+ about context creation and release.
+ <p>
+ When the Rhino runtime needs to create new <A HREF="../../../org/mozilla/javascript/Context.html" title="class in org.mozilla.javascript"><CODE>Context</CODE></A> instance during
+ execution of <A HREF="../../../org/mozilla/javascript/Context.html#enter()"><CODE>Context.enter()</CODE></A> or <A HREF="../../../org/mozilla/javascript/Context.html" title="class in org.mozilla.javascript"><CODE>Context</CODE></A>, it will call
+ <A HREF="../../../org/mozilla/javascript/ContextFactory.html#makeContext()"><CODE>makeContext()</CODE></A> of the current global ContextFactory.
+ See <A HREF="../../../org/mozilla/javascript/ContextFactory.html#getGlobal()"><CODE>getGlobal()</CODE></A> and <A HREF="../../../org/mozilla/javascript/ContextFactory.html#initGlobal(org.mozilla.javascript.ContextFactory)"><CODE>initGlobal(ContextFactory)</CODE></A>.
+ <p>
+ It is also possible to use explicit ContextFactory instances for Context
+ creation. This is useful to have a set of independent Rhino runtime
+ instances under single JVM. See <A HREF="../../../org/mozilla/javascript/ContextFactory.html#call(org.mozilla.javascript.ContextAction)"><CODE>call(ContextAction)</CODE></A>.
+ <p>
+ The following example demonstrates Context customization to terminate
+ scripts running more then 10 seconds and to provide better compatibility
+ with JavaScript code using MSIE-specific features.

+ import org.mozilla.javascript.*;
+
