    "abstract": "We clarify under what circumstances the nucleon--nucleon final state\ninteraction fixes the energy dependence of the total cross--section for the\nreaction $NN \\to NNx$ close to production threshold, where $x$ can be any meson\nwhose interaction with the nucleon is not too strong. We strongly criticize the\nprocedure used recently by several authors to include the final state\ninteraction in the reactions under discussion. In addition, we give a formula\nthat allows one to estimate the effect of the initial state interaction for the\nproduction of heavy mesons.",
