#  You can restart or check the status of your FAD client from a console as root by:
#   su / sudo to root 
#    then
#   cd /usr/local/think
#    then
#   ./loader (To restart your client)
#    or
#   ./server -list (To check the status)
#
#  If you have any questions please visit http://usalug.org/phpBB2/viewforum.php?f=92

#  The above may get integrated in to a secondary script or as part of a
#  case function in this script.

#0 integrate additional documentation into script from original

 # 1. This function will not continue without some type of entry

 # 3. Would like way to clean this function up but it works for now.
 # 4. This function requires the get_input function to properly format
 #+   the output due to issues with certain version of bash
