Submits a value (identified by I<Identifier>, see below) to the daemon which
will dispatch it to all it's write-plugins. The I<Valuelist> is a
-colon-seperated list of values, either an integer if the data-source is a
-counter, of a double if the data-source if of type "gauge". You can submit an
-undefined gauge-value by using B<U>. When submitting B<U> to a counter the
-behavior is undefined.

value on failure and never return zero.
+=head1 ABSTRACTION LAYER
+
+Shipped with the sourcecode comes the Perl-Module L<Collectd::Unixsock> which
+provides an abstraction layer over the actual socket connection. It can be
+found in the directory F<contrib/PerlLib>. If you want to use Perl to
+communicate with the daemon, you're encouraged to use and expand this module.
