+ senf::ppi::connect() establishes a connection between two modules or, to be more precise,
+ between two connectors. It will connect any input to any output connector as long as one is
+ active and the other passive.
+
+ If a module has an output connector called \c output, the module may be directly specified
+ as \a source argument. In the same way, if a module has an input connector called \c input,
+ the module may be given directly as \a target argument. This simplifies the most common case
+ of a module with one input and one output connector.
