Extending Tcl
In the previous section, we saw how easy it is to create and access
Java objects from Tcl. In this section, we'll look at some more
detailed examples, with an emphasis on using Java to extend
Tcl. Traditionally, this role has been played by C. Since you are
extending Tcl, we'll assume that will use Tcl Blend to add Java into
the mix, and examine how you might do so.
