Right. This would be the "application mapper".
Now, there are a few things here:
We may also want to do the same to the input, because some even more
twisted apps will not even accept that as a parameter. So:
(file k, file m, file n) myapp(file l) {
  app{
    l>"input.txt";
    myapp;
    k<"output.crd"
    m<"output.prd"
    n<"output.rtf"
  }
}

This may become a little trickier when inputs (or even outputs) are
arrays, so we may need nicer schemes:
(file o) myapp(file i[]){
  app{
    i[x=*] > "input"+$1; (or something like that)
    myapp;
    ...
  }
}
