-          renaming is possible.  Note only non-resident files can be written to
-          so you may find that some very small files (<500 bytes or so) cannot
-          be written to.
-          While we cannot guarantee that it will not damage any data, we have
-          so far not received a single report where the driver would have
-          damaged someones data so we assume it is perfectly safe to use.
-          Note:  While write support is safe in this version (a rewrite from
-          scratch of the NTFS support), it should be noted that the old NTFS
-          write support, included in Linux 2.5.10 and before (since 1997),
-          is not safe.
-          This is currently useful with TopologiLinux.  TopologiLinux is run
-          on top of any DOS/Microsoft Windows system without partitioning your
-          hard disk.  Unlike other Linux distributions TopologiLinux does not
-          need its own partition.  For more information see

+        help
+          With FUSE it is possible to implement a fully functional filesystem
+          in a userspace program.
+          There's also companion library: libfuse.  This library along with
+          utilities is available from the FUSE homepage:
+          <http://fuse.sourceforge.net/>
+          See <file:Documentation/filesystems/fuse.txt> for more information.
+          See <file:Documentation/Changes> for needed library/utility version.
+          If you want to develop a userspace FS, or if you want to use
+          a filesystem based on FUSE, answer Y or M.

+          safe, write support available.  For write support you must also
+          say Y to "NTFS write support" below.
+          There are also a number of user-space tools available, called
+          ntfsprogs.  These include ntfsundelete and ntfsresize, that work
+          without NTFS support enabled in the kernel.
+          This is a rewrite from scratch of Linux NTFS support and replaced
+          the old NTFS code starting with Linux 2.5.11.  A backport to
+          the Linux 2.4 kernel series is separately available as a patch
+          from the project web site.
+          For more information see <file:Documentation/filesystems/ntfs.txt>
+          and <http://www.linux-ntfs.org/>.
+          To compile this file system support as a module, choose M here: the

+          performed by the driver as well as additional debugging messages to
+          be written to the system log.  Note that debugging messages are
+          disabled by default.  To enable them, supply the option debug_msgs=1
+          at the kernel command line when booting the kernel or as an option
+          to insmod when loading the ntfs module.  Once the driver is active,
+          you can enable debugging messages by doing (as root):
+          echo 1 > /proc/sys/fs/ntfs-debug
+          Replacing the "1" with "0" would disable debug messages.
+          If you leave debugging messages disabled, this results in little
+          overhead, but enabling debug messages results in very significant
+          slowdown of the system.
+          When reporting bugs, please try to have available a full dump of

+          renaming is possible.  Note only non-resident files can be written to
+          so you may find that some very small files (<500 bytes or so) cannot
+          be written to.
+          While we cannot guarantee that it will not damage any data, we have
+          so far not received a single report where the driver would have
+          damaged someones data so we assume it is perfectly safe to use.
+          Note:  While write support is safe in this version (a rewrite from
+          scratch of the NTFS support), it should be noted that the old NTFS
+          write support, included in Linux 2.5.10 and before (since 1997),
+          is not safe.
+          This is currently useful with TopologiLinux.  TopologiLinux is run

+          hard disk.  Unlike other Linux distributions TopologiLinux does not
+          need its own partition.  For more information see
