This is a somewhat special test: I wanted to test a new approach for defining modules more CPAN-style and capsulated.
So in FHEM/ (the legacy library path) just exists a very minimal loader for legacy loading a module. The loader dispatches the module initialization to FHEM::WWW:Serienjunkies.
Surprisingly, this works and supports the common idioms from the legacy module development.
See als the list for the testing device for further entertainment.
