 * from a list of segments by alternating between "/" and the encoded segment. For example the
 * segments `["a", "b"]` build "/a/b" and the segments `["a", "b", ""]` build "/a/b/".
 *
 * If a path's last segment is the empty string then the path ends with "/". This class always
 * builds non-empty paths: if the path is omitted it defaults to "/". The default path's segment
 * list is a single empty string: `[""]`.

Docker and similar tools also use an **internal cache** when building the image, if a file hasn't changed since the last time building the container image, then it will **reuse the same layer** created the last time, instead of copying the file again and creating a new layer from scratch.
