+<p>Javassist (<i>Java</i> programming <i>assist</i>ant) makes bytecode
+engineering simple.  It is a class library for editing
 bytecode in Java; it enables Java programs to define a new class at
 runtime and to modify a given class file when the JVM loads it.
 
 <p>The most significant class of this package is <code>CtClass</code>.
 See the description of this class first.
 
+<p>To know the version number of this package, type the following command:
