* This script will allow you to configure the ntp.conf and ntp.keys files *
* that control Meridian II GPS NTP daemon operation. *
* *
* You will be able to create new MD5 authentication keys which are stored *
* in the ntp.keys file. *
* *
* You will be able to update the authentication related commands in the *
* ntp.conf file. *
* *
* You will be able to configure the “broadcast” mode of operation, with *
* or without authentication. If you supply the multicast address instead *
* of your network broadcast address, then you will be able to configure *
* the time-to-live of the multicast packets. *
* *
* The changes you make now will not take effect until you re-boot the *
* Meridian II GPS. If you make a mistake, just re-run ntpconfig prior to *
* re-booting. *
* *
* You will now be prompted for the necessary set up parameters. *
