+/**
+ * Import satellite standard magnitudes from the qs.mag file (Mike McCants).
+ *
+ * Source: https://www.mmccants.org/programs/sgp4/tle_satinfo.txt
+ * Mirror: https://raw.githubusercontent.com/barolfe/satellite-tracker/master/qs.mag
+ *
+ * Format (fixed-width):
+ *   0-4   NORAD catalog number
+ *   6     Flag: 'd'=decayed, 't'=tumbling, ' '=normal
+ *   8-14  International designation
+ *   15-28 Satellite name
+ *   ~29+  Standard magnitude (at 1000 km range, 50% illumination phase)
+ *         followed by sizes and RCS
+ *
+ * Usage:
+ *   php import_qsmag.php [path-to-qs.mag]
+ *   php import_qsmag.php          (downloads from mirror)
