Old Problems in Low-Energy $K N$ Physics and Perspectives Opening Up at   New Machines
  We survey the open problems in low--energy $KN$ physics, in the perspective of using the new machines presently planned, such as the $\phi$--factory DA$\Phi$NE at I.N.F.N. Nat. Labs. in Frascati (as a source of {\sl tagged}, low--energy kaons) and the KAON Factory at TRIUMF (as a producer of intense, intermediate--energy kaon beams).
