54   *
55   * Here is a basic installer which installs the free installer
56   * software itself. The free installer application accepts this a
57   * class name as one of the parameters. This object class
58   * <I>`ixenon.free.install.BasicInstaller'</I> is dynamically loaded by
59   * name using <B>Class.forName()</B> method. Once the class is loaded
60   * a single object is instantiated. The software vendor company name
61   * and product name as retrieved from the object. After the operator
62   * decides to install the package by clicking the [INSTALL] on the
63   * installer frame GUI, the method <B>installPackage</B> is install.
64   * <P>
65   * 
66   * The method @see #installPackage performs the entire installation.
67   * For the BasicInstaller, a tree of @see Installable objects is
68   * created.  Since @see AbstractInstallable objects are subclass of
69   * @see javax.swing.tree.DefaultMutableTreeNode then the method
70   * preorderEnumeration() can be called. Thus the installation is
71   * actually performed by interating (or rather enumerating over the
72   * tree) calling the <B>install()</B> on each tree node.
73   * <P>
