[Pkg-tcltk-devel] Bug#720143: {tcl, tk}8.5: leaves alternatives after purge: /usr/bin/tclsh, /usr/bin/wish

the removal is done in tcltk-defaults from experimental.

$ cat tcl.preinst

set -e

case "$1" in
	# Currently the alternatives mechanism is not used
	if dpkg --compare-versions "$2" lt-nl "8.6.0+2"; then
	    update-alternatives --remove-all tclsh || true

I assume this works good enough in practice, but fails when a versioned tcl8.x
was installed without the tcl package installed. same for tk.
