This is something we would like to do, but really no specific work in
that direction has been done yet.

If everything is well, you would need modify:

  -- src/Guile

     For the Glue proper.
     The public interfaces are in "src/Guile/Scheme/*.hh".

  -- src/System/Boot/init_texmacs.cc

     For initialization.

  -- src/Texmacs/Texmacs/texmacs.cc

     To remove the use of the GUILE and put MzScheme in place.
     
  -- configure.in
     src/makefile
     src/common.makefile.in
     COMPILE

     To make required changes to the build system and its
     documentation.

  -- Adaptations for Guile-specific features in Scheme code.

     Look mainly for boot.scm and compat.scm in progs/core/boot. 

  -- More fixes for all the various things which did not went as well
     as expected.

Joris is planning to support the "multiple interpreter" feature using
a plugin system and dynamic module loading. That would also probably
require the introduction of libtool in the build system if we want a
reasonably clean solution.

But any hackish and not well integrated solution wich actually sort of
works will be a big step in the right direction anyway.

I think we should best discuss this in on IRC.

The first step will be to actually understand how the current "switch"
feature works. You would have to check (from memory no garantee)
fold.scm and std-markup.scm. From that point on, we can probably do
everything by extending what is already there.
