+Starting with collectd 4.9, this may also be a block in which further options

+If enabled, collectd will export all global symbols of the plugin (and of all
+libraries loaded as dependencies of the plugin) and, thus, makes those symbols
+available for resolving unresolved symbols in subsequently loaded plugins if
+that is supported by your system. By default, this is disabled.
+
+This is useful (or possibly even required), e.E<nbsp>g., when loading a plugin
+that embeds some scripting language into the daemon (e.E<nbsp>g. the C<perl>
+or C<python> plugins). Scripting languages usually provide means to load
+extensions written in C. Those extensions require symbols provided by the
+interpreter, which is loaded as a dependency of the respective collectd
+plugin. See the documentation of those plugins (e.E<nbsp>g.,
+L<collectd-perl(5)> or L<collectd-python(5)>) for details.
