Question:option trace, how to only display ENTER and EXIT messages?

When adding option trace: inside a proc, Maple display trace of all assignments. I only want to see the --> enter  and <-- exit messages,.

I can't figure how to do that. Any suggestions?

   r:=n:
   B:-boo(r);
 end proc:
end module:
B := module()
 export boo:=proc(n)
   option trace:
   local k;

   k:=n;
   RETURN();
 end proc:
end module:

{--> enter foo, args = 1, 2, diff(y(x), x) = sin(x)

1

{--> enter boo, args = 1

1

<-- exit boo (now in foo) = }

<-- exit foo (now at top level) = }
