#! /usr/bin/perl
#
# send_dpc_url.pl
#
# Purpose:
#    This is a function to email the Data Product Center's URL to the
#    Project Data Center.  Running this script will overwrite an 
#    existing email address and URL that the PDC has on 'file' for 
#    the Data Product Center.
#
# Notes:
#    1)  Successfully updating the DPC URL using this script does not
#        result in any kind of response that indicates the update was
#        successful.  A web-based form on the AIM Science Data System 
#        website (http://aim.hamptonu.edu/sds/ under "Data Services/Admin")
#        provides the same functionality as this script and indicates
#        success or failure.  
#    2)  This is hard coded to GATS right now.  After the server is moved 
#        to Hamton U the variable $toAdress will need to be changed.
