Overview

A PathComponent represents either the Wolverine.config.script_path directory, or a subdirectory of it. Calling (nearly) any method on it will cause it to look in the filesystem at the location it refers to for a file or directory matching the method name. These results are cached.

Calling a method that maps to a directory will return a new PathComponent with a path referring to that directory.

Calling a method that maps to a file (with ‘.lua’ automatically appended to the name) will load the file via Script and call it with the arugments passed, returning the result (#method_missing).
