By wrapper library, I am referring to a Mercury library which provides
a Mercury interface to an existing C library.  I think that the
(module) name should be the name of the library the module is
wrapping.

With regard to mercury_tcltk and similar libraries, I think that the
name should be unnecessary (I already know that I'm using Mercury),
and I can't see that it helps (the manual isn't very clear, but I
don't think that the importing it will cause the imported libraries
(e.g. mtcltk, mtk) to be imported into the calling module.  My memory
is also that the samples imported mtcltk and mtk directly, rather than
going through mercury_tcltk.

With regard to naming, I think that the Tcl wrapper module should be
called 'tcl' and the Tk interface built on it should be called 'tk',
possibly also containing sub-modules as necessary.  There should be no
necessity for some kind of a wrapper module with imports like
mercury_tcltk.  I certainly intend to have the Gtk+ modules using
module names 'gtk', 'glib', and similar.
