vTcl can deal with imported code fragments, but not whole applications.
This is due to the fact that vTcl has preconceived notions about how to
manage windows. Your code which drives the "." toplevel may be in conflict.
Also, vTcl uses dynamic introspection on the current intepreter for
information on the loaded/running application. It does not parse tcl. As a
result, any code not contained in a procedure will be lost when the
application is resaved (this also impacts some GUI code, but that's another
story). The order is not preserved because tcl does not preserve procedure
creation order (see "info procs"). The "main" and "init" procedures are
added to allow a main code body (that which would otherwise appear outside
of a procedure) and a special place to do var initialization and image
loading which your application may depend on these when being edited in the
vTcl graphical environment.
