+  Sometimes, a directory is ordinarily accessed through a symbolic

+@var{from} with @var{to} when it appears in a directory name.  For

+the same file.  The @var{from} string is actually a regular expression

+matching to an incorrect part of the original directory name.  The
+@var{to} string should be an ordinary absolute directory name.  Do not
