+=head1 NAME
+
+Monitoring::Plugin::Threshold - class for handling Monitoring::Plugin thresholds.
+
+=head1 SYNOPSIS
+
+    # NB: This is an internal Monitoring::Plugin class.
+    # See Monitoring::Plugin itself for public interfaces.
+
+    # Constructor
+    $t = Monitoring::Plugin::Threshold->set_thresholds(
+        warning  => $warning_range_string,
+        critical => $critical_range_string,
+    );
+
+    # Value checking - returns CRITICAL if in the critical range,
+    # WARNING if in the warning range, and OK otherwise
+    $status = $t->get_status($value);
+
+    # Accessors - return the associated N::P::Range object
+    $warning_range  = $t->warning;
+    $critical_range = $t->critical;
+
+
+=head1 DESCRIPTION
+
+Internal Monitoring::Plugin class for handling threshold data. See
+Monitoring::Plugin for public interfaces.
+
+A threshold object contains (typically) a pair of ranges, associated
+with a particular severity e.g.
+
+  warning  => range1
+  critical => range2
