+restore them into <path> or just list the tree roots.
+

+verbose.

+-i::
+ignore errors.

+
+-t <location>::
+use <location> to read root tree.
+
+-f <offset>::
+use <offset> to read fs tree.
+
+-u <block>::
+use given superblock mirror identified by <block>.
+
+-r <rootid>::
+use <rootid> as root objectid.
+
+-d::
+find dir.
+
+-l::
+list tree roots.
+
+EXIT STATUS
+-----------
+'btrfs restore' returns a zero exist status if it succeeds. Non zero is
+returned in case of failure.
+
+AVAILABILITY
+------------
+'btrfs' is part of btrfs-progs. Btrfs filesystem is currently under heavy
+development,
+and not suitable for any uses other than benchmarking and review.
+Please refer to the btrfs wiki http://btrfs.wiki.kernel.org for
+further details.
