                  Developers deploying in a production environment
                  should still favor the 1.3.3 release.

         The Tcl/Java project's goal is to make integrating the
         Java platform and the Tcl scripting language as easy
         as possible. The project actually consists of two
         distinct packages, called Tcl Blend and Jacl.
         It is important to understand what each package provides
         and in what situations one might choose to use Jacl
         or Tcl Blend.
         </P>

         <P>
         <B>Jacl</B> is a self-contained implementation of a Tcl
         interpreter, written entirely in Java. Jacl also
         includes features that facilitate communication between
         a Java interpreter and a Tcl interpreter. Jacl is typically
         used to incorporate scripting functionality into an existing
         Java application. Jacl is the ideal solution for users
         that want to add Tcl scripting to a Java application, but
         don't want to deal with the complexities of native code
         that come with Tcl Blend.
         </P>

         <P>
         <B>Tcl Blend</B> is a Tcl extension that makes use of
         <B>JNI</B> to facilitate communication between a Java
         interpreter and a Tcl interpreter. Tcl Blend is typically
         used to load a Java interpreter into an existing Tcl
         process, so that functionality implemented in Java can
         be accessed via Tcl. One can also load Tcl Blend and
         Tcl into a Java process, which is a great way to add
         scripting functionality to an existing Java application.
         Because Tcl Blend is a normal Tcl extension, one can
         use it with other popular Tcl extensions like Tk,
         Expect, and Itcl.
         </P>

         <P>
         Tcl Blend and Jacl define both a Tcl API and a Java
         API that make it easy to call Java code from Tcl or
         call Tcl code from Java. For example, one could
         allocate a Java object in a Tcl script and interactively
         invoke Java methods on the object. It is also easy to use
         the supplied API to evaluate a Tcl procedure from
         a Java method or implement Tcl procudures in Java.
         The flexible API and wealth of implementation options
         provided by the Tcl/Java project make integrating
         Tcl and Java easy.
