1.1 Overview of GNU Parted
==========================

GNU Parted is a program for creating and manipulating partition tables.

  This documentation is written with the assumption that the reader has
some understanding of partitioning and file systems.

  GNU Parted was designed to minimize the chance of data loss.  For
example, it was designed to avoid data loss during interruptions (like
power failure) and performs many safety checks.  However, there could be
bugs in GNU Parted, so you should back up your important files before
running Parted.

  The GNU Parted homepage is <https://www.gnu.org/software/parted>.  The
library and frontend themselves can be downloaded from
<https://ftp.gnu.org/gnu/parted>.  You can also find a listing of
mailing lists, notes for contributing and more useful information on the
web site.

  Please send bug reports to <bug-parted@gnu.org>.  When sending bug
reports, please include the version of GNU Parted.  Please include the
output from these commands (for disk '/dev/hda'):

     # parted /dev/hda unit s print free

  Feel free to ask for help on this list -- just check that your
question isn't answered here first.  If you don't understand the
documentation, please tell us, so we can explain it better.  General
philosophy is: if you need to ask for help, then something needs to be
fixed so you (and others) don't need to ask for help.

  Also, we'd love to hear your ideas :-)

1.2 Software Required for the use of Parted
===========================================

If you're installing or compiling Parted yourself, you'll need to have
some other programs installed.  If you are compiling Parted, you will
need both the normal and devel packages of these programs installed:

   * GNU parted source is available either as a source tarball:

     <https://git.savannah.gnu.org/gitweb/?p=parted.git>

     or using git (See the README-hacking instructions):

     <https://git.savannah.gnu.org/gitweb/?p=parted.git>

   * libuuid, part of the e2fsprogs package.  If you don't have this,
     you can get it from:

     <http://web.mit.edu/tytso/www/linux/e2fsprogs.html>

     If you want to compile Parted and e2fsprogs, note that you will
     need to 'make install' and 'make install-libs' e2fsprogs.

   * GNU Readline (optional), available from

     <https://ftp.gnu.org/gnu/readline>

     If you are compiling Parted, and you don't have readline, you can
     disable Parted's readline support with the '--disable-readline'
     option for 'configure'.

   * GNU gettext (or compatible software) for compilation, if
     internationalisation support is desired.

     <https://ftp.gnu.org/gnu/gettext>

1.3 Platforms on which GNU Parted runs
======================================

Hopefully, this list will grow a lot.  If you do not have one of these
platforms, then you can use a rescue disk and a static binary of GNU
Parted.

GNU/Linux
     Linux versions 2.0 and up, on Alpha, x86 PCs, PC98, Macintosh
     PowerPC, Sun hardware.

GNU/Hurd

1.4 Terms of distribution for GNU Parted
========================================

GNU Parted is free software, covered by the GNU General Public License
Version 3, or (at your option) any later version.  This should have been
included with the Parted distribution, in the COPYING file.  If not, see
<http://www.gnu.org/licenses/>.

  Libparted is considered part of GNU Parted.  It is covered by the GNU
General Public License.  It is NOT released under the GNU Lesser General
Public License (LGPL).

1.5 Building GNU Parted
=======================

If you want to compile GNU Parted, this is generally done with:

     $ ./configure
     $ make

  However, there are a few options for 'configure':

'--without-readline'
     turns off use of readline.  This is useful for making rescue disks,
     etc., where few libraries are available.

'--disable-debug'
     don't include assertions

'--disable-nls'
     turns off native language support.  This is useful for use with old
     versions of glibc, or a trimmed down version of glibc suitable for
     rescue disks.

'--disable-shared'
     turns off shared libraries.  This may be necessary for use with old
     versions of GNU libc, if you get a compile error about a "spilled
     register".  Also useful for boot/rescue disks.

'--enable-discover-only'
     support only reading/probing (reduces size considerably)

'--enable-mtrace'
     enable malloc() debugging

'--enable-read-only'
     disable writing (for debugging)

1.5.1 Introduction
------------------

If you want to run GNU Parted on a machine without GNU/Linux installed,
or you want to modify a root or boot partition, use GParted Live:
<https://gparted.org/livecd.php>.

2 Using Parted
**************

2.1 Introduction to Partitioning
================================

Partitioning is the process of dividing a storage device into local
sections, called partitions, which help organize multiple filesystems
and their associated operating systems.

  A storage device presents itself as a sequence of bytes, numbered
starting from zero and increasing until the maximum capacity of the
device is reached.  Bytes are normally read and written a sector at a
time, rather than individually.  Each sector contains a fixed number of
bytes, with the number determined by the device.

     +------------------------------------------------------------+
     |            storage device with no partitions               |
     +------------------------------------------------------------+
     0 start                                                    end

  In order to store multiple filesystems, a storage device can be
divided up in to multiple partitions.  Each partition can be thought of
as an area which contains a real filesystem inside of it.  To show where
these partitions are on the device a small table is written at the
start, shown as PT in the diagram below.  This table is called a
partition table, or disklabel, and also stores the type of each
partition and some flags.

     +--+---------------+----------------+------------------------+
     |PT|  Partition 1  |  Partition 2   |  Partition 3           |
     +--+---------------+----------------+------------------------+
     0 start                                                    end

2.2 Using GNU Parted
====================

Parted has two modes: command line and interactive.  Parted should
always be started with:

     # parted DEVICE

where DEVICE is the hard disk device to edit.  (If you're lazy and omit
the DEVICE argument, Parted will attempt to guess which device you
want.)

  In command line mode, this is followed by one or more commands.  For
example:

     # parted /dev/sda mklabel gpt mkpart P1 ext3 1MiB 8MiB

Options (like '--help') can only be specified on the command line.

  In interactive mode, commands are entered one at a time at a prompt,
and modify the disk immediately.  For example:

     (parted) mklabel gpt
     (parted) mkpart P1 ext3 1MiB 8MiB

Unambiguous abbreviations are allowed.  For example, you can type "p"
instead of "print", and "u" instead of "units".  Commands can be typed
either in English, or your native language (if your language has been
translated).  This may create ambiguities.  Commands are
case-insensitive.

  Numbers indicating partition locations can be whole numbers or
decimals.  The suffix selects the unit, which may be one of those
described in *note unit::, except CHS and compact.  If no suffix is
given, then the default unit is assumed.  Negative numbers count back
from the end of the disk, with "-1s" indicating the sector at the end of
the disk.  Parted will compute sensible ranges for the locations you
specify (e.g.  a range of +/- 500 MB when you specify the location in
"G"). Use the sector unit "s" to specify exact locations.  With
parted-2.4 and newer, IEC binary units like "MiB", "GiB", "TiB", etc.,
specify exact locations as well.  *Note IEC binary units::.

  If you don't give a parameter to a command, Parted will prompt you for
it.  For example:

     (parted) mklabel
     New disk label type? gpt

  Parted will always warn you before doing something that is potentially
dangerous, unless the command is one of those that is inherently
dangerous (viz., rm, mklabel and mkpart).  Since many partitioning
systems have complicated constraints, Parted will usually do something
slightly different to what you asked.  (For example, create a partition
starting at 10.352Mb, not 10.4Mb) If the calculated values differ too
much, Parted will ask you for confirmation.

2.3 Command Line Options
========================

When invoked from the command line, Parted supports the following
syntax:

     # parted [OPTION] DEVICE [COMMAND [ARGUMENT]]

  Available options and commands follow.  For detailed explanations of
the use of Parted commands, see *note Command explanations::.  Options
begin with a hyphen, commands do not:

  Options:

'-h'
'--help'
     display a help message

'-l'
'--list'
     lists partition layout on all block devices

'-m'
'--machine'
     display output in machine parseable format

'-j'
'--json'
     display output in JSON format

'-s'
'--script'
     never prompt the user

'-f'
'--fix'
     automatically answer exceptions with "fix" in script mode, which is
     useful for: GPT header not including full disk size; moving the
     backup GPT table to the end of the disk; MAC fix missing partition
     map entry; etc.

'-a alignment-type'
'--align alignment-type'
     Set alignment for newly created partitions, valid alignment types
     are: none, cylinder, minimal and optimal.

'-v'
'--version'
     display the version

2.4 Parted Session Commands
===========================

GNU Parted provides the following commands:

  Note that after version 2.4, the following commands were removed:
check, cp, mkfs, mkpartfs, move, resize.

2.4.1 align-check
-----------------

 -- Command: align-check ALIGN-TYPE N

     Determine whether the starting sector of partition N meets the
     disk's selected alignment criteria.  ALIGN-TYPE must be 'minimal',
     'optimal' or an abbreviation.  When in script mode, if the
     partition does not meet the alignment requirement, exit with status
     1; otherwise (including on older kernels for which alignment data
     is not available), continue processing any remaining commands.
     Without '--script', print either 'N aligned' or 'N not aligned'.

     Example:

          (parted) align-check minimal 1
          1 aligned

2.4.2 disk_set
--------------

 -- Command: disk_set FLAG STATE

     Changes a flag on the disk.  A flag can be either "on" or "off".
     Some or all of these flags will be available, depending on what
     disk label you are using:

     'pmbr_boot'
          (GPT) - this flag enables the boot flag on the GPT's
          protective MBR partition.

     The disk's flags are displayed by the print command on the "Disk
     Flags:" line.  They are also output as the last field of the disk
     information in machine mode.

          (parted) disk_set pmbr_boot on

     Set the PMBR's boot flag.

2.4.3 disk_toggle
-----------------

 -- Command: disk_toggle FLAG

     Toggle the state of the disk flag.

2.4.4 help
----------

 -- Command: help [COMMAND]

     Prints general help, or help on COMMAND.

     Example:

          (parted) help mklabel

     Print help for the mklabel command.

2.4.5 mklabel
-------------

 -- Command: mklabel LABEL-TYPE

     Creates a new disk label, of type LABEL-TYPE.  The new disk label
     will have no partitions.  This command (normally) won't technically
     destroy your data, but it will make it basically unusable, and you
     will need to use the rescue command (*note Related information::)
     to recover any partitions.  Parted works on all partition tables.
     (1)

     LABEL-TYPE must be one of these supported disk labels:
        * aix
        * amiga
        * bsd
        * dvh
        * gpt
        * loop (raw disk access)
        * mac
        * msdos
        * pc98
        * sun

     Example:

          (parted) mklabel msdos

     Create an MS-DOS disk label.  This is still the most common disk
     label for PCs.

   ---------- Footnotes ----------

   (1) Everyone seems to have a different word for "disk label" -- these
are all the same thing: partition table, partition map.

2.4.6 mkpart
------------

 -- Command: mkpart [PART-TYPE NAME FS-TYPE] START END

     Creates a new partition, _without_ creating a new file system on
     that partition.  This is useful for creating partitions for file
     systems (or LVM, etc.)  that Parted doesn't support.  You may
     specify a file system type, to set the appropriate partition code
     in the partition table for the new partition.  FS-TYPE is required
     for data partitions (i.e., non-extended partitions).  START and END
     are the offset from the beginning of the disk, that is, the
     "distance" from the start of the disk.

     PART-TYPE is one of 'primary', 'extended' or 'logical', and may be
     specified only with 'msdos' or 'dvh' partition tables.  A NAME must
     be specified for a 'gpt' partition table.  Neither PART-TYPE nor
     NAME may be used with a 'sun' partition table.

     FS-TYPE must be one of these supported file systems:
        * btrfs
        * ext2, ext3, ext4
        * fat16, fat32
        * hfs, hfs+, hfsx
        * hp-ufs
        * jfs
        * linux-swap, linux-swap(new,old,v0,v1)
        * nilfs2
        * ntfs
        * reiserfs
        * sun-ufs
        * ufs
        * xfs

     For example, the following creates a logical partition that will
     contain an ext2 file system.  The partition will start at the
     beginning of the disk, and end 692.1 megabytes into the disk.

          (parted) mkpart logical 0.0 692.1

     Now, we will show how to partition a low-end flash device
     ("low-end", as of 2011/2012).  For such devices, you should use
     4MiB-aligned partitions(1).  This command creates a tiny
     place-holder partition at the beginning, and then uses all
     remaining space to create the partition you'll actually use:

          $ parted -s /dev/sdX -- mklabel msdos \
              mkpart primary fat32 64s 4MiB \
              mkpart primary fat32 4MiB -1s

     Note the use of '--', to prevent the following '-1s' last-sector
     indicator from being interpreted as an invalid command-line option.
     The above creates two empty partitions.  The first is unaligned and
     tiny, with length less than 4MiB. The second partition starts
     precisely at the 4MiB mark and extends to the end of the device.

     The next step is typically to create a file system in the second
     partition:

          $ mkfs.vfat /dev/sdX2

   ---------- Footnotes ----------

   (1) Cheap flash drives will be with us for a long time to come, and,
for them, 1MiB alignment is not enough.  Use at least 4MiB-aligned
partitions.  For details, see Arnd Bergman's article,
<http://lwn.net/Articles/428584/> and its many comments.

2.4.7 name
----------

 -- Command: name NUMBER NAME

     Sets the name for the partition NUMBER (GPT, Mac, MIPS and PC98
     only).  The name can be placed in quotes.  And depending on the
     shell may need to also be wrapped in single quotes so that the
     shell doesn't strip off the double quotes.

     Example:

          (parted) name 2 'Secret Documents'

     Set the name of partition 2 to 'Secret Documents'.

2.4.8 print
-----------

 -- Command: print [PRINT-TYPE]

     Displays the partition table on the device parted is editing, or
     detailed information about a particular partition.

     PRINT-TYPE is optional, and can be one of 'devices', 'free',
     'list', or 'all'.

     'devices'
          display all active block devices

     'free'
          display information about free unpartitioned space on the
          current block device

     'list, all'
          display the partition tables of all active block devices

     Example:

          (parted) print
          Model: ATA Samsung SSD 850 (scsi)
          Disk /dev/sda: 2684MB
          Sector size (logical/physical): 512B/512B
          Partition Table: msdos
          Disk Flags:

          Number  Start   End     Size    Type     File system     Flags
           1      1049kB  1000MB  999MB   primary                  boot, lba
           2      1000MB  2300MB  1299MB  primary  ext2            lba
           3      2300MB  2500MB  200MB   primary  linux-swap(v1)  lba
          (parted) print free
          Model: ATA Samsung SSD 850 (scsi)
          Disk /dev/sda: 2684MB
          Sector size (logical/physical): 512B/512B
          Partition Table: msdos
          Disk Flags:

          Number  Start   End     Size    Type     File system     Flags
                  16.4kB  1049kB  1032kB           Free Space
           1      1049kB  1000MB  999MB   primary                  boot, lba
           2      1000MB  2300MB  1299MB  primary  ext2            lba
           3      2300MB  2500MB  200MB   primary  linux-swap(v1)  lba
                  2500MB  2684MB  185MB            Free Space


2.4.9 quit
----------

 -- Command: quit

     Quits Parted.

     It is only after Parted exits that the Linux kernel knows about the
     changes Parted has made to the disks.  However, the changes caused
     by typing your commands will _probably_ be made to the disk
     immediately after typing a command.  However, the operating
     system's cache and the disk's hardware cache may delay this.

2.4.10 rescue
-------------

 -- Command: rescue START END
     Rescue a lost partition that used to be located approximately
     between START and END.  If such a partition is found, Parted will
     ask you if you want to create a partition for it.  This is useful
     if you accidentally deleted a partition with parted's rm command,
     for example.

     Example:

          (parted) print
          Model: ATA Samsung SSD 850 (scsi)
          Disk /dev/sda: 2684MB
          Sector size (logical/physical): 512B/512B
          Partition Table: msdos
          Disk Flags:

          Number  Start   End     Size    Type     File system     Flags
           1      1049kB  1000MB  999MB   primary                  boot, lba
           2      1000MB  2300MB  1299MB  primary  ext4            lba
          (parted) rm
          Partition number? 2
          (parted) print
          Model: ATA Samsung SSD 850 (scsi)
          Disk /dev/sda: 2684MB
          Sector size (logical/physical): 512B/512B
          Partition Table: msdos
          Disk Flags:

          Number  Start   End     Size    Type     File system     Flags
           1      1049kB  1000MB  999MB   primary                  boot, lba

     OUCH! We deleted our ext4 partition!!!  Parted comes to the
     rescue...

          (parted) rescue
          Start? 1000
          End? 2684
          Information: A ext4 primary partition was found at 1000MB ->
          2300MB.  Do you want to add it to the partition table?
          Yes/No/Cancel? y
          (parted) print
          Model: ATA Samsung SSD 850 (scsi)
          Disk /dev/sda: 2684MB
          Sector size (logical/physical): 512B/512B
          Partition Table: msdos
          Disk Flags:

          Number  Start   End     Size    Type     File system     Flags
           1      1049kB  1000MB  999MB   primary                  boot, lba
           2      1000MB  2300MB  1299MB  primary  ext4            lba

     It's back!  :)

2.4.11 resizepart
-----------------

 -- Command: resizepart NUMBER END

     Moves the END position of partition NUMBER.  Note that this does
     not modify any filesystem present in the partition.  If you wish to
     do this, you will need to use external tools, such as 'resize2fs'.

     When growing a partition you will want to grow the filesystem
     afterwards, but when shrinking, you need to shrink the filesystem
     before the partition.

2.4.12 rm
---------

 -- Command: rm NUMBER

     Removes the partition with number NUMBER.  If you accidentally
     delete a partition with this command, use *note rescue:: to recover
     it.  Also, you can use the gpart program (*note Related
     information::) to recover damaged disk labels.

     Note for msdos disk labels: if you delete a logical partition, all
     logical partitions with a larger partition number will be
     renumbered.  For example, if you delete a logical partition with a
     partition number of 6, then logical partitions that were number 7,
     8 and 9 would be renumbered to 6, 7 and 8 respectively.  This
     means, for example, that you have to update '/etc/fstab' on
     GNU/Linux systems.

     Example:

          (parted) rm 3

     Remove partition 3.

2.4.13 select
-------------

 -- Command: select DEVICE

     Selects the device, DEVICE, for Parted to edit.  The device can be
     a Linux hard disk device, a partition, a software RAID device, LVM
     logical volume, or disk image file.

     Example:

          (parted) select /dev/hdb

     Select '/dev/hdb' (the slave device on the first ide controller on
     Linux) as the device to edit.

2.4.14 set
----------

 -- Command: set NUMBER FLAG STATE

     Changes a flag on the partition with number NUMBER.  A flag can be
     either "on" or "off".  Some or all of these flags will be
     available, depending on what disk label you are using:

     'bios_grub'
          (GPT) - Enable this to record that the selected partition is a
          GRUB BIOS partition.

     'legacy_boot'
          (GPT) - this flag is used to tell special purpose software
          that the GPT partition may be bootable.

     'bls_boot'
          (MS-DOS, GPT) - Enable this to indicate that the selected
          partition is a Linux Boot Loader Specification compatible
          /boot partition.

     'boot'
          (Mac, MS-DOS, PC98) - should be enabled if you want to boot
          off the partition.  The semantics vary between disk labels.
          For MS-DOS disk labels, only one partition can be bootable.
          If you are installing LILO on a partition that partition must
          be bootable.  For PC98 disk labels, all ext2 partitions must
          be bootable (this is enforced by Parted).

     'msftdata'
          (GPT) - This flag identifies partitions that contain Microsoft
          filesystems (NTFS or FAT). It may optionally be set on Linux
          filesystems to mimic the type of configuration created by
          parted 3.0 and earlier, in which a separate Linux filesystem
          type code was not available on GPT disks.  This flag can only
          be removed within parted by replacing it with a competing
          flag, such as boot or msftres.

     'msftres'
          (MS-DOS,GPT) - This flag identifies a "Microsoft Reserved"
          partition, which is used by Windows.  Note that this flag
          should not normally be set on Windows filesystem partitions
          (those that contain NTFS or FAT filesystems).

     'irst'
          (MS-DOS, GPT) - this flag identifies an Intel Rapid Start
          Technology partition.

     'esp'
          (MS-DOS, GPT) - this flag identifies a UEFI System Partition.
          On GPT it is an alias for boot.

     'chromeos_kernel'
          (GPT) - this flag indicates a partition that can be used with
          the Chrome OS bootloader and verified boot implementation.

     'lba'
          (MS-DOS) - this flag can be enabled to tell MS DOS, MS Windows
          9x and MS Windows ME based operating systems to use Linear
          (LBA) mode.

     'root'
          (Mac) - this flag should be enabled if the partition is the
          root device to be used by Linux.

     'linux-home'
          (GPT) - Enable this to indicate that the selected partition is
          a Linux /home partition.

     'swap'
          (MS-DOS, GPT, Mac) - this flag should be enabled if the
          partition is the swap device to be used by Linux.

     'hidden'
          (MS-DOS, PC98) - this flag can be enabled to hide partitions
          from Microsoft operating systems.

     'raid'
          (MS-DOS) - this flag can be enabled to tell linux the
          partition is a software RAID partition.

     'LVM'
          (MS-DOS) - this flag can be enabled to tell linux the
          partition is a physical volume.

     'PALO'
          (MS-DOS) - this flag can be enabled so that the partition can
          be used by the Linux/PA-RISC boot loader, palo.

     'PREP'
          (MS-DOS, GPT) - this flag can be enabled so that the partition
          can be used as a PReP boot partition on PowerPC PReP or IBM
          RS6K/CHRP hardware.

     'DIAG'
          (MS-DOS) - Enable this to indicate that a partition can be
          used as a diagnostics / recovery partition.

     The print command displays all enabled flags for each partition.

     Example:

          (parted) set 1 boot on

     Set the 'boot' flag on partition 1.

2.4.15 toggle
-------------

 -- Command: toggle NUMBER FLAG

     Toggle the state of FLAG on partition NUMBER.

2.4.16 unit
-----------

 -- Command: unit UNIT

     Selects the current default unit that Parted will use to display
     locations and capacities on the disk and to interpret those given
     by the user if they are not suffixed by an UNIT.

     UNIT may be one of:

     's'
          sector (n bytes depending on the sector size, often 512)

     'B'
          byte

     'KiB'
          kibibyte (1024 bytes)

     'MiB'
          mebibyte (1048576 bytes)

     'GiB'
          gibibyte (1073741824 bytes)

     'TiB'
          tebibyte (1099511627776 bytes)

     'kB'
          kilobyte (1000 bytes)

     'MB'
          megabyte (1000000 bytes)

     'GB'
          gigabyte (1000000000 bytes)

     'TB'
          terabyte (1000000000000 bytes)

     '%'
          percentage of the device (between 0 and 100)

     'cyl'
          cylinders (related to the BIOS CHS geometry)

     'chs'
          cylinders, heads, sectors addressing (related to the BIOS CHS
          geometry)

     'compact'
          This is a special unit that defaults to megabytes for input,
          and picks a unit that gives a compact human readable
          representation for output.

     The default unit apply only for the output and when no unit is
     specified after an input number.  Input numbers can be followed by
     an unit (without any space or other character between them), in
     which case this unit apply instead of the default unit for this
     particular number, but CHS and cylinder units are not supported as
     a suffix.  If no suffix is given, then the default unit is assumed.
     Parted will compute sensible ranges for the locations you specify
     (e.g., a range of +/- 500 MB when you specify the location in "G",
     and a range of +/- 500 KB when you specify the location in "M") and
     will select the nearest location in this range from the one you
     wrote that satisfies constraints from both the operation, the
     filesystem being worked on, the disk label, other partitions and so
     on.  Use the sector unit "s" to specify exact locations (if they do
     not satisfy all constraints, Parted will ask you for the nearest
     solution).  Note that negative numbers count back from the end of
     the disk, with "-1s" pointing to the last sector of the disk.

     Note that as of parted-2.4, when you specify start and/or end
     values using IEC binary units like "MiB", "GiB", "TiB", etc.,
     parted treats those values as exact, and equivalent to the same
     number specified in bytes (i.e., with the "B" suffix), in that it
     provides _no_ "helpful" range of sloppiness.  Contrast that with a
     partition start request of "4GB", which may actually resolve to
     some sector up to 500MB before or after that point.  Thus, when
     creating a partition, you should prefer to specify units of bytes
     ("B"), sectors ("s"), or IEC binary units like "MiB", but not "MB",
     "GB", etc.

     Example:

          (parted) unit compact
          (parted) print
          Disk geometry for /dev/hda: 0kB - 123GB

          BIOS cylinder,head,sector geometry: 14946,255,63.  Each cylinder
          is 8225kB.
          Disk label type: msdos
          Number  Start       End         Type      File system  Flags

A.1 GNU Free Documentation License
==================================

                     Version 1.3, 3 November 2008

     Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
     <https://fsf.org/>

     Everyone is permitted to copy and distribute verbatim copies
     of this license document, but changing it is not allowed.

  0. PREAMBLE

     The purpose of this License is to make a manual, textbook, or other
     functional and useful document "free" in the sense of freedom: to
     assure everyone the effective freedom to copy and redistribute it,
     with or without modifying it, either commercially or
     noncommercially.  Secondarily, this License preserves for the
     author and publisher a way to get credit for their work, while not
     being considered responsible for modifications made by others.

     This License is a kind of "copyleft", which means that derivative
     works of the document must themselves be free in the same sense.
     It complements the GNU General Public License, which is a copyleft
     license designed for free software.

     We have designed this License in order to use it for manuals for
     free software, because free software needs free documentation: a
     free program should come with manuals providing the same freedoms
     that the software does.  But this License is not limited to
     software manuals; it can be used for any textual work, regardless
     of subject matter or whether it is published as a printed book.  We
     recommend this License principally for works whose purpose is
     instruction or reference.

  1. APPLICABILITY AND DEFINITIONS

     This License applies to any manual or other work, in any medium,
     that contains a notice placed by the copyright holder saying it can
     be distributed under the terms of this License.  Such a notice
     grants a world-wide, royalty-free license, unlimited in duration,
     to use that work under the conditions stated herein.  The
     "Document", below, refers to any such manual or work.  Any member
     of the public is a licensee, and is addressed as "you".  You accept
     the license if you copy, modify or distribute the work in a way
     requiring permission under copyright law.

     A "Modified Version" of the Document means any work containing the
     Document or a portion of it, either copied verbatim, or with
     modifications and/or translated into another language.

     A "Secondary Section" is a named appendix or a front-matter section
     of the Document that deals exclusively with the relationship of the
     publishers or authors of the Document to the Document's overall
     subject (or to related matters) and contains nothing that could
     fall directly within that overall subject.  (Thus, if the Document
     is in part a textbook of mathematics, a Secondary Section may not
     explain any mathematics.)  The relationship could be a matter of
     historical connection with the subject or with related matters, or
     of legal, commercial, philosophical, ethical or political position
     regarding them.

     The "Invariant Sections" are certain Secondary Sections whose
     titles are designated, as being those of Invariant Sections, in the
     notice that says that the Document is released under this License.
     If a section does not fit the above definition of Secondary then it
     is not allowed to be designated as Invariant.  The Document may
     contain zero Invariant Sections.  If the Document does not identify
     any Invariant Sections then there are none.

     The "Cover Texts" are certain short passages of text that are
     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
     that says that the Document is released under this License.  A
     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
     be at most 25 words.

     A "Transparent" copy of the Document means a machine-readable copy,
     represented in a format whose specification is available to the
     general public, that is suitable for revising the document
     straightforwardly with generic text editors or (for images composed
     of pixels) generic paint programs or (for drawings) some widely
     available drawing editor, and that is suitable for input to text
     formatters or for automatic translation to a variety of formats
     suitable for input to text formatters.  A copy made in an otherwise
     Transparent file format whose markup, or absence of markup, has
     been arranged to thwart or discourage subsequent modification by
     readers is not Transparent.  An image format is not Transparent if
     used for any substantial amount of text.  A copy that is not
     "Transparent" is called "Opaque".

     Examples of suitable formats for Transparent copies include plain
     ASCII without markup, Texinfo input format, LaTeX input format,
     SGML or XML using a publicly available DTD, and standard-conforming
     simple HTML, PostScript or PDF designed for human modification.
     Examples of transparent image formats include PNG, XCF and JPG.
     Opaque formats include proprietary formats that can be read and
     edited only by proprietary word processors, SGML or XML for which
     the DTD and/or processing tools are not generally available, and
     the machine-generated HTML, PostScript or PDF produced by some word
     processors for output purposes only.

     The "Title Page" means, for a printed book, the title page itself,
     plus such following pages as are needed to hold, legibly, the
     material this License requires to appear in the title page.  For
     works in formats which do not have any title page as such, "Title
     Page" means the text near the most prominent appearance of the
     work's title, preceding the beginning of the body of the text.

     The "publisher" means any person or entity that distributes copies
     of the Document to the public.

     A section "Entitled XYZ" means a named subunit of the Document
     whose title either is precisely XYZ or contains XYZ in parentheses
     following text that translates XYZ in another language.  (Here XYZ
     stands for a specific section name mentioned below, such as
     "Acknowledgements", "Dedications", "Endorsements", or "History".)
     To "Preserve the Title" of such a section when you modify the
     Document means that it remains a section "Entitled XYZ" according
     to this definition.

     The Document may include Warranty Disclaimers next to the notice
     which states that this License applies to the Document.  These
     Warranty Disclaimers are considered to be included by reference in
     this License, but only as regards disclaiming warranties: any other
     implication that these Warranty Disclaimers may have is void and
     has no effect on the meaning of this License.

  2. VERBATIM COPYING

     You may copy and distribute the Document in any medium, either
     commercially or noncommercially, provided that this License, the
     copyright notices, and the license notice saying this License
     applies to the Document are reproduced in all copies, and that you
     add no other conditions whatsoever to those of this License.  You
     may not use technical measures to obstruct or control the reading
     or further copying of the copies you make or distribute.  However,
     you may accept compensation in exchange for copies.  If you
     distribute a large enough number of copies you must also follow the
     conditions in section 3.

     You may also lend copies, under the same conditions stated above,
     and you may publicly display copies.

  3. COPYING IN QUANTITY

     If you publish printed copies (or copies in media that commonly
     have printed covers) of the Document, numbering more than 100, and
     the Document's license notice requires Cover Texts, you must
     enclose the copies in covers that carry, clearly and legibly, all
     these Cover Texts: Front-Cover Texts on the front cover, and
     Back-Cover Texts on the back cover.  Both covers must also clearly
     and legibly identify you as the publisher of these copies.  The
     front cover must present the full title with all words of the title
     equally prominent and visible.  You may add other material on the
     covers in addition.  Copying with changes limited to the covers, as
     long as they preserve the title of the Document and satisfy these
     conditions, can be treated as verbatim copying in other respects.

     If the required texts for either cover are too voluminous to fit
     legibly, you should put the first ones listed (as many as fit
     reasonably) on the actual cover, and continue the rest onto
     adjacent pages.

     If you publish or distribute Opaque copies of the Document
     numbering more than 100, you must either include a machine-readable
     Transparent copy along with each Opaque copy, or state in or with
     each Opaque copy a computer-network location from which the general
     network-using public has access to download using public-standard
     network protocols a complete Transparent copy of the Document, free
     of added material.  If you use the latter option, you must take
     reasonably prudent steps, when you begin distribution of Opaque
     copies in quantity, to ensure that this Transparent copy will
     remain thus accessible at the stated location until at least one
     year after the last time you distribute an Opaque copy (directly or
     through your agents or retailers) of that edition to the public.

     It is requested, but not required, that you contact the authors of
     the Document well before redistributing any large number of copies,
     to give them a chance to provide you with an updated version of the
     Document.

  4. MODIFICATIONS

     You may copy and distribute a Modified Version of the Document
     under the conditions of sections 2 and 3 above, provided that you
     release the Modified Version under precisely this License, with the
     Modified Version filling the role of the Document, thus licensing
     distribution and modification of the Modified Version to whoever
     possesses a copy of it.  In addition, you must do these things in
     the Modified Version:

       A. Use in the Title Page (and on the covers, if any) a title
          distinct from that of the Document, and from those of previous
          versions (which should, if there were any, be listed in the
          History section of the Document).  You may use the same title
          as a previous version if the original publisher of that
          version gives permission.

       B. List on the Title Page, as authors, one or more persons or
          entities responsible for authorship of the modifications in
          the Modified Version, together with at least five of the
          principal authors of the Document (all of its principal
          authors, if it has fewer than five), unless they release you
          from this requirement.

       C. State on the Title page the name of the publisher of the
          Modified Version, as the publisher.

       D. Preserve all the copyright notices of the Document.

       E. Add an appropriate copyright notice for your modifications
          adjacent to the other copyright notices.

       F. Include, immediately after the copyright notices, a license
          notice giving the public permission to use the Modified
          Version under the terms of this License, in the form shown in
          the Addendum below.

       G. Preserve in that license notice the full lists of Invariant
          Sections and required Cover Texts given in the Document's
          license notice.

       H. Include an unaltered copy of this License.

       I. Preserve the section Entitled "History", Preserve its Title,
          and add to it an item stating at least the title, year, new
          authors, and publisher of the Modified Version as given on the
          Title Page.  If there is no section Entitled "History" in the
          Document, create one stating the title, year, authors, and
          publisher of the Document as given on its Title Page, then add
          an item describing the Modified Version as stated in the
          previous sentence.

       J. Preserve the network location, if any, given in the Document
          for public access to a Transparent copy of the Document, and
          likewise the network locations given in the Document for
          previous versions it was based on.  These may be placed in the
          "History" section.  You may omit a network location for a work
          that was published at least four years before the Document
          itself, or if the original publisher of the version it refers
          to gives permission.

       K. For any section Entitled "Acknowledgements" or "Dedications",
          Preserve the Title of the section, and preserve in the section
          all the substance and tone of each of the contributor
          acknowledgements and/or dedications given therein.

       L. Preserve all the Invariant Sections of the Document, unaltered
          in their text and in their titles.  Section numbers or the
          equivalent are not considered part of the section titles.

       M. Delete any section Entitled "Endorsements".  Such a section
          may not be included in the Modified Version.

       N. Do not retitle any existing section to be Entitled
          "Endorsements" or to conflict in title with any Invariant
          Section.

       O. Preserve any Warranty Disclaimers.

     If the Modified Version includes new front-matter sections or
     appendices that qualify as Secondary Sections and contain no
     material copied from the Document, you may at your option designate
     some or all of these sections as invariant.  To do this, add their
     titles to the list of Invariant Sections in the Modified Version's
     license notice.  These titles must be distinct from any other
     section titles.

     You may add a section Entitled "Endorsements", provided it contains
     nothing but endorsements of your Modified Version by various
     parties--for example, statements of peer review or that the text
     has been approved by an organization as the authoritative
     definition of a standard.

     You may add a passage of up to five words as a Front-Cover Text,
     and a passage of up to 25 words as a Back-Cover Text, to the end of
     the list of Cover Texts in the Modified Version.  Only one passage
     of Front-Cover Text and one of Back-Cover Text may be added by (or
     through arrangements made by) any one entity.  If the Document
     already includes a cover text for the same cover, previously added
     by you or by arrangement made by the same entity you are acting on
     behalf of, you may not add another; but you may replace the old
     one, on explicit permission from the previous publisher that added
     the old one.

     The author(s) and publisher(s) of the Document do not by this
     License give permission to use their names for publicity for or to
     assert or imply endorsement of any Modified Version.

  5. COMBINING DOCUMENTS

     You may combine the Document with other documents released under
     this License, under the terms defined in section 4 above for
     modified versions, provided that you include in the combination all
     of the Invariant Sections of all of the original documents,
     unmodified, and list them all as Invariant Sections of your
     combined work in its license notice, and that you preserve all
     their Warranty Disclaimers.

     The combined work need only contain one copy of this License, and
     multiple identical Invariant Sections may be replaced with a single
     copy.  If there are multiple Invariant Sections with the same name
     but different contents, make the title of each such section unique
     by adding at the end of it, in parentheses, the name of the
     original author or publisher of that section if known, or else a
     unique number.  Make the same adjustment to the section titles in
     the list of Invariant Sections in the license notice of the
     combined work.

     In the combination, you must combine any sections Entitled
     "History" in the various original documents, forming one section
     Entitled "History"; likewise combine any sections Entitled
     "Acknowledgements", and any sections Entitled "Dedications".  You
     must delete all sections Entitled "Endorsements."

  6. COLLECTIONS OF DOCUMENTS

     You may make a collection consisting of the Document and other
     documents released under this License, and replace the individual
     copies of this License in the various documents with a single copy
     that is included in the collection, provided that you follow the
     rules of this License for verbatim copying of each of the documents
     in all other respects.

     You may extract a single document from such a collection, and
     distribute it individually under this License, provided you insert
     a copy of this License into the extracted document, and follow this
     License in all other respects regarding verbatim copying of that
     document.

  7. AGGREGATION WITH INDEPENDENT WORKS

     A compilation of the Document or its derivatives with other
     separate and independent documents or works, in or on a volume of a
     storage or distribution medium, is called an "aggregate" if the
     copyright resulting from the compilation is not used to limit the
     legal rights of the compilation's users beyond what the individual
     works permit.  When the Document is included in an aggregate, this
     License does not apply to the other works in the aggregate which
     are not themselves derivative works of the Document.

     If the Cover Text requirement of section 3 is applicable to these
     copies of the Document, then if the Document is less than one half
     of the entire aggregate, the Document's Cover Texts may be placed
     on covers that bracket the Document within the aggregate, or the
     electronic equivalent of covers if the Document is in electronic
     form.  Otherwise they must appear on printed covers that bracket
     the whole aggregate.

  8. TRANSLATION

     Translation is considered a kind of modification, so you may
     distribute translations of the Document under the terms of section
     4.  Replacing Invariant Sections with translations requires special
     permission from their copyright holders, but you may include
     translations of some or all Invariant Sections in addition to the
     original versions of these Invariant Sections.  You may include a
     translation of this License, and all the license notices in the
     Document, and any Warranty Disclaimers, provided that you also
     include the original English version of this License and the
     original versions of those notices and disclaimers.  In case of a
     disagreement between the translation and the original version of
     this License or a notice or disclaimer, the original version will
     prevail.

     If a section in the Document is Entitled "Acknowledgements",
     "Dedications", or "History", the requirement (section 4) to
     Preserve its Title (section 1) will typically require changing the
     actual title.

  9. TERMINATION

     You may not copy, modify, sublicense, or distribute the Document
     except as expressly provided under this License.  Any attempt
     otherwise to copy, modify, sublicense, or distribute it is void,
     and will automatically terminate your rights under this License.

     However, if you cease all violation of this License, then your
     license from a particular copyright holder is reinstated (a)
     provisionally, unless and until the copyright holder explicitly and
     finally terminates your license, and (b) permanently, if the
     copyright holder fails to notify you of the violation by some
     reasonable means prior to 60 days after the cessation.

     Moreover, your license from a particular copyright holder is
     reinstated permanently if the copyright holder notifies you of the
     violation by some reasonable means, this is the first time you have
     received notice of violation of this License (for any work) from
     that copyright holder, and you cure the violation prior to 30 days
     after your receipt of the notice.

     Termination of your rights under this section does not terminate
     the licenses of parties who have received copies or rights from you
     under this License.  If your rights have been terminated and not
     permanently reinstated, receipt of a copy of some or all of the
     same material does not give you any rights to use it.

  10. FUTURE REVISIONS OF THIS LICENSE

     The Free Software Foundation may publish new, revised versions of
     the GNU Free Documentation License from time to time.  Such new
     versions will be similar in spirit to the present version, but may
     differ in detail to address new problems or concerns.  See
     <https://www.gnu.org/licenses/>.

     Each version of the License is given a distinguishing version
     number.  If the Document specifies that a particular numbered
     version of this License "or any later version" applies to it, you
     have the option of following the terms and conditions either of
     that specified version or of any later version that has been
     published (not as a draft) by the Free Software Foundation.  If the
     Document does not specify a version number of this License, you may
     choose any version ever published (not as a draft) by the Free
     Software Foundation.  If the Document specifies that a proxy can
     decide which future versions of this License can be used, that
     proxy's public statement of acceptance of a version permanently
     authorizes you to choose that version for the Document.

  11. RELICENSING

     "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
     World Wide Web server that publishes copyrightable works and also
     provides prominent facilities for anybody to edit those works.  A
     public wiki that anybody can edit is an example of such a server.
     A "Massive Multiauthor Collaboration" (or "MMC") contained in the
     site means any set of copyrightable works thus published on the MMC
     site.

     "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
     license published by Creative Commons Corporation, a not-for-profit
     corporation with a principal place of business in San Francisco,
     California, as well as future copyleft versions of that license
     published by that same organization.

     "Incorporate" means to publish or republish a Document, in whole or
     in part, as part of another Document.

     An MMC is "eligible for relicensing" if it is licensed under this
     License, and if all works that were first published under this
     License somewhere other than this MMC, and subsequently
     incorporated in whole or in part into the MMC, (1) had no cover
     texts or invariant sections, and (2) were thus incorporated prior
     to November 1, 2008.

     The operator of an MMC Site may republish an MMC contained in the
     site under CC-BY-SA on the same site at any time before August 1,
     2009, provided the MMC is eligible for relicensing.

ADDENDUM: How to use this License for your documents
====================================================

To use this License in a document you have written, include a copy of
the License in the document and put the following copyright and license
notices just after the title page:

       Copyright (C)  YEAR  YOUR NAME.
       Permission is granted to copy, distribute and/or modify this document
       under the terms of the GNU Free Documentation License, Version 1.3
       or any later version published by the Free Software Foundation;
       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
       Texts.  A copy of the license is included in the section entitled ``GNU
       Free Documentation License''.

  If you have Invariant Sections, Front-Cover Texts and Back-Cover
Texts, replace the "with...Texts." line with this:

         with the Invariant Sections being LIST THEIR TITLES, with
         the Front-Cover Texts being LIST, and with the Back-Cover Texts
         being LIST.

  If you have Invariant Sections without Cover Texts, or some other
combination of the three, merge those two alternatives to suit the
situation.

  If your document contains nontrivial examples of program code, we
recommend releasing these examples in parallel under your choice of free
software license, such as the GNU General Public License, to permit
their use in free software.
