+The @command{fsck.bookmarkfs} program checks and optionally repairs a
+BookmarkFS filesystem.
+
+Unlike @command{fsck} on general-purpose filesystems (e.g. ext4),
+this program does not check the integrity or validity of a bookmark file --
+the underlying filesystem containing the bookmark storage is responsible for
+that.
+Instead, it checks for bookmark names that are not valid as filename
+(e.g. contains slash characters).

+Available options:

+@table @option
+@item -o backend=@var{name}
+The backend used by the filesystem (@pxref{Backends}).
