-       on top of each other when building a ClassLoader - so if you have
-       plugin jars with dependencies on other jars, the "lower level"
-       dependency jars should be loaded first.

-       found in it are included as if you had used the following

-       files in that directory which completely match the regex
-       (anchored on both ends) will be included.
-
-       If a 'dir' option (with or without a regex) is used and nothing
-       is found that matches, a warning will be logged.
