+Crossing Into Targets:
 
+	configure a29k +target=a29k
 
+    will configure the tools such that when compiled in an a29k
+    development environment, the resulting development environment can
+    be used to create programs intended for an a29k.  Again, this does
+    not necessarily mean that the new development environment can be
+    run on an a29k.  That would depend on the development environment
+    used to build these tools.
 
+    If you've been following along this walk through, then you've
+    already built an a29k environment, namely gcc-a29k.  Let's pretend
+    you use gcc-a29k to build the current configuration.
+
+    Gcc-a29k builds programs intended for the a29k so the new
+    development environment will be intended for use on an a29k.  That
+    is, this new gcc consists of programs that are foreign to your
+    sun4.  They cannot be run on your sun4.
+
+    The process of building this configuration is another a bootstrap.
+    This bootstrap is also a cross to a29k.  Because this type of
+    build is both a bootstrap and a cross to a29k, it is sometimes
+    referred to as a "cross into" a29k.  This new development
+    environment isn't really a cross development environment at all.
+    It is intended to run on an a29k to produce programs for an a29k.
+    You'll remember that this makes it, by definition, an a29k native
+    compiler.  "Crossing into" has been introduced here not because it
+    is a type of cross development environment, but because it is
+    frequently confused one.  The process is "a cross" but the
+    resulting development environment is a native development
+    environment.
+
+    You could not have built this configuration with stage3, because
+    stage3 doesn't provide an a29k environment.  Instead it provides a
+    sun4 environment.
+
+    If you happen to have an a29k lying around, you could now use
+    this fresh development environment on the a29k to three stage
+    these tools all over again.  This process would look just like it
+    did when we built the native sun4 development environment because
+    we would be building another native development environment, this
+    one on a29k.
+
+    
+The Three Party Cross:
+
+    So far you've seen that our development environment source must be
+    configured for a specific host and for a specific target.  You've
+    also seen that the resulting development environment depends on
+    the development environment used in the build process.
+
+    When all four match identically, that is, the configured host, the
+    configured target, the environment presented by the development
+    environment used in the build, and the machine on which the
+    resulting development environment is intended to run, then the new
+    development environment will be a native development environment.
+
+    When all four match except the configured host, then we can assume
+    that the development environment used in the build is some form of
+    library emulation.
+
+    When all four match except for the configured target, then the
+    resulting development environment will be a simple cross
+    development environment.
 
+    When all four match except for the host on which the development
+    environment used in the build runs, the build process is a "cross
+    into" and the resulting development environment will be native to
+    some other machine.
 
+    Most of the other permutations do exist in some form, but only one
+    more is interesting to the current discussion.
 
+	configure a29k +target=sun3
 
+    will configure the tools such that when compiled in an a29k
+    development environment, the resulting development environment can
+    be used to create programs intended for a sun3.  Again, this does
+    not necessarily mean that the new development environment can be
+    run on an a29k.  That would depend on the development environment
+    used to build these tools.
 
+    If you are still following along, then you have two a29k
+    development environments, the native development environment that
+    runs on a29k, and the simple cross that runs on your sun4.  If you
+    use the a29k native development environment on the a29k, you will
+    be doing the same thing we did a while back, namely building a
+    simple cross from a29k to sun3.  Let's pretend that instead, you
+    use gcc-a29k, the simple cross development environment that runs
+    on sun4 but produces programs for a29k.
 
+    The resulting development environment will run on a29k because
+    that's what gcc-a29k builds, a29k programs.  This development
+    environment will produce programs for a sun3 because that is how
+    it was configured.  This means that the resulting development
+    environment is a simple cross.
 
+    There really isn't a common name for this process because very few
+    development environments are capable of being configured this
+    extensively.  For the sake of discussion, let's call this process
+    a "three party cross".

-    If configured for host sun3 and target a29k, this implies that we

-    Host sun3 only implies that the source will be compiled on a sun3.
-    In fact, it need not be actually compiled on a sun3.  If the

-    were available on a dec3100, then source configured for host sun3
-    could be cross compiled to create an a29k development environment
-    intended to be run on a sun3.
