Last change on this file since 2021 was 1448, checked in by Ehouarn Millour, 14 years ago

Small bug fix in the way the traceur.def file is read : using a fixed format for reading that file is not a good idea (things are easily misread), using a free format makes more sense.
Added default initialization for planets (1 tracer) when there is no traceur.def file.
