# Summary
#    Print out the setting for the ADMIN_RESTRICTIONS_<lsnr_name> parameter
#    or NONE if not found
#
# Implementation
#    The ADMIN_RESTRICTIONS parameter is specified in 
#    the listener.ora file for each listener as
#
#     ADMIN_RESTRICTIONS_<lsnr_name>=ON|TRUE|OFF|FALSE
#
#    and is not case-sensitive. Search the listener.ora file for
#    the presence of this parameter starting on a new line. Prints
#    the result as em_result=<none_or_param_value>|<lsnr_name_and_desc>.
#    E.g., em_result=listenerAdmin=ON
#	 or, em_result=listenerAdmin=NONE
