Some bugs.

[Thomas Volkmar Worm]

Just using the example I found some bugs:

$ bin/example -l --port

Returns 80, the default, which is a bug, because it should return an error because of the missing parameter for --port.

$ bin/example -l --port xx

Returns 80, the default, which is a bug, because it should return an error because the given parameter for --port is not an integer as it is defined.

Similar bugs exist, when having no defaults defined.
