+@item Readlink mode

+@command{readlink} outputs the value of the given symbolic link.
+If @command{readlink} is invoked with an argument other than the pathname
+of a symbolic link, it exits with a non-zero exit code.
+
+@item Canonicalize mode
+
+@command{readlink} outputs the absolute name of the given file which contains
+no `.', `..' components nor any repeated path separators (`/') or symlinks.
+In any of the path components is missing or unavailable,
