pair - generate a catalogue containing pairs of objects from input catalogue

pair [options...]

"-d " only output N (N - 1) / 2 distinct pairs

'pair' reads a catalogue from stdin and writes to stdout a catalogue which has object items with the same names as in the input cat but where each object is a 2-vector formed from a pair of input objects. By default all N (N - 1) pairs are output.
