+Note that run-time dependencies that are only recommended by __TARGET_PKG__ may not yet be installed at the time __TARGET_PKG__ is tested, as there is no explicit dependency link between them and in that case most CPAN clients default to install prerequisites in alphabetic order.
+However, they will be installed when __TASK_PKG__ is, thus will be available when you actually use __TARGET_PKG__.
