-#define DESCRIPTION "\
-This plugin tests a radius server to see if it is accepting connections.\n\
-\n\
-The server to test must be specified in the invocation, as well as a user\n\
-name and password. A configuration file may also be present. The format of\n\
-the configuration file is described in the radiusclient library sources.\n\
-\n\
-The password option presents a substantial security issue because the\n\
-password can be determined by careful watching of the command line in\n\
-a process listing. This risk is exacerbated because nagios will\n\
-run the plugin at regular prdictable intervals. Please be sure that\n\
-the password used does not allow access to sensitive system resources,\n\
-otherwise compormise could occur.\n"
