#    Description

#      Script will upload file passed on STDIN to URL defined in $server

#      using variable name $urlVarName.

#      Filename may also be passed on command line

#      It assumes the remote server will return the exact contents which

#      is then used to compare to what was sent

#      It will return the following codes

#        0 - success

#         1 - Could not find LWP::Simple module

#         2 - file not passed on STDIN

#         3 - Contents returned by server do not match our local copy

#         4 - URL call returned a "not found" error

#         5 - no key given for report contents

#         6 - no key given for report date

#         7 - no key given for hostname

#         8 - no key given for client

#         9 - no key given for serial number
