2 * This utility takes an ICCID number on the command line (needs to be
3 * read from the plastic with human eyeballs and entered by the operator),
4 * reads card provisioning data from fcsim1-prov-db, and generates
5 * an fc-simtool command script for programming one FCSIM1 card. The
6 * intent is that the output of this program will be piped directly
7 * into fc-simtool.
