#!/bin/sh
# restart this script with wish \
	exec wish $0 "$@"

As for picking an alternate wish, you'd have to embed a shell 
script in the tcl code on alternate lines, using the same
continued comment trick.  Tcl interprets the second and 
third line in that example as a single comment, due to the
line continuation character, '\'.  /bin/sh treats it as
one comment line, and one script line.  Another option is
having autoconf check for wish, wish8.2, wish8.0, etc. and
generate tcltkgrass from tcltkgrass.in, etc.

Not that any of this helps on Win32.
