+
+
+=head1 DESCRIPTION
+
+This module is part of the Nagios::Plugin family, a set of modules
+for simplifying the creation of Nagios plugins. This module exports
+convenience functions for the class methods provided by 
+Nagios::Plugin. It is intended for those who prefer a simpler 
+functional interface, and who do not need the additional 
+functionality of Nagios::Plugin.
+
+=head2 Exports
+
+Nagios status code constants are exported by default:
+
+    OK
+    WARNING
+    CRITICAL
+    UNKNOWN
+    DEPENDENT
+
+as are the following functions:
+
+    nagios_exit
+    nagios_die
+    check_messages
+
+The following variables are exported only on request:
+
+    %ERRORS
+    %STATUS_TEXT
+
+
+=head2 Functions
+
+The following functions are supported:
+
+=over 4
+
+=item nagios_exit( CODE, $message )
+
+Exit with return code CODE, and a standard nagios message of the
+form "PLUGIN CODE - $message".
+
+=item nagios_die( $message, [CODE] )
+
+Same as nagios_exit(), except that CODE is optional, defaulting
+to UNKNOWN.
+
+=item check_messages( critical => \@crit, warning => \@warn )
+
+Convenience function to check a set of message arrays and return
+an appropriate nagios return code and/or a result message. Returns
+only a return code in scalar context; returns a return code and an
+error message in list context i.e.
+
+    # Scalar context
+    $code = check_messages(critical => \@crit, warning => \@warn);
+    # List context
+    ($code, $msg) = check_messages(critical => \@crit, warning => \@warn);
+
+check_messages() accepts the following named arguments:
+
+=over 4
+
+=item critical => ARRAYREF
+
+An arrayref of critical error messages - check_messages() returns 
+CRITICAL if this arrayref is non-empty. Mandatory.
+
+=item warning => ARRAYREF
+
+An arrayref of warning error messages - check_messages() returns
+WARNING if this arrayref is non-empty ('critical' is checked
+first). Mandatory.
+
+=item ok => ARRAYREF | SCALAR
+
+An arrayref of informational messages (or a single scalar message),
+used in list context if both the 'critical' and 'warning' arrayrefs
+are empty. Optional.
+
+=item join => SCALAR
+
+A string used to join the relevant array to generate the message 
+string returned in list context i.e. if the 'critical' array @crit
+is non-empty, check_messages would return:
+
+    join( $join, @crit )
+
+as the result message. Optional; default: ' ' (space).
+
+=item join_all => SCALAR
+
+By default, only one set of messages are joined and returned in the
+result message i.e. if the result is CRITICAL, only the 'critical'
+messages are included in the result; if WARNING, only the 'warning' 
+messages are included; if OK, the 'ok' messages are included (if
+supplied) i.e. the default is to return an 'errors-only' type 
+message.
+
+If join_all is supplied, however, it will be used as a string to
+join the resultant critical, warning, and ok messages together i.e.
+all messages are joined and returned.
