joinPath(path, *args)
Join the given relative paths to the given path.
Returns a unicode path.
The path should be well-formed, and not end in a /
unless it is
the root path. It can be either a string (ascii only) or unicode.
The positional arguments are relative paths to be added to the
path as new path segments. The path may be absolute or relative.
A segment may not start with a '/ because that would be confused
with an absolute path. A segment may not end with a
/ because we
do not allow
/ at the end of relative paths. A segment may
consist of . or .. to mean "the same place", or "the parent path"
respectively. A
. should be removed and a
.. should cause the
segment to the left to be removed. joinPath(
/', ..
) should
raise an exception.
