+=head1 VALUE-LIST
+
+A value list describes one data-set as handled by collectd. It is a colon
+(C<:>) separated list of the time and the values. Each value is either given
+as an integer if the data-type is a counter, or as a double if the data-type
+is a gauge value. A literal C<U> is interpreted as an undefined gauge value.
+The number of values and the data-types have to match the type specified in
+the identifier (see L<types.db(5)> for details). The time is specified as
+epoch (i.E<nbsp>e., standard UNIX time) or as a literal C<N> which will be
+interpreted as now.
