 .. function:: join(path1[, path2[, ...]])
 
-   Join one or more path components intelligently.  If any component is an absolute
-   path, all previous components (on Windows, including the previous drive letter,
-   if there was one) are thrown away, and joining continues.  The return value is
-   the concatenation of *path1*, and optionally *path2*, etc., with exactly one
-   directory separator (``os.sep``) following each non-empty part except the last.
-   (This means that an empty last part will result in a path that ends with a
-   separator.)  Note that on Windows, since there is a current directory for
-   each drive, ``os.path.join("c:", "foo")`` represents a path relative to the
-   current directory on drive :file:`C:` (:file:`c:foo`), not :file:`c:\\foo`.
