Usage:

xtrack [options]
   [options:]
     -f     <norad-filename> (default: norad.txt or what's in xtrack.ini)

     -rlon  <ref-pos lon> (default: 5)
     -rlat  <ref-pos lat> (default: 52)
     -rep_time <repetition time> (default: 1.0)
     -run_at_start
     -log <log_file> : use logfile for rotor results

     -m     <map-filename> (default: earthmap.gif)
     -ppl   <value> (default:  2)
     -max_azimspeed <value> in degr/sec, show err in degrees; def=0=no limit: show speed (predict only) 
  ppl=pixels per longitude.
  ppl=1 means: 1 pixel=1 degree, so size is 360x180 pixels.
