This function assists in creating URL paths from individual segments. This
is particularly useful for building virtual source objects. It takes a bunch
of path segments and returns an absolute path. The default behavior is to
guess the trailing slash based on the presence of a dot in the last path
segment. If you want to override the detection you can explicitly pass
True to enforce a trailing slash or
False to avoid it.
