Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Given an absolute (or expandable) file path, returns the shortest path relative to any $LOAD_PATH entry the file lives under, or nil if the file is outside every entry. The shortest match wins because a deeper LOAD_PATH entry yields a shorter subpath that better matches require resolution.
