D.1.1 Platform-specific types, macros and functions
---------------------------------------------------
It's sometimes necessary to provide nonstandard, platform-specific
features to developers. The C library is traditionally the lowest
library layer, so it makes sense for it to provide these low-level
features. However, including these features in the C library may be a
disadvantage if another package provides them as well as there will be
two conflicting versions of them. Also, the features won't be
available to projects that do not use the GNU C Library but use other
GNU tools, like GCC.
The current guidelines are:
* If the header file provides features that only make sense on a
particular machine architecture and have nothing to do with an
operating system, then the features should ultimately be provided
as GCC built-in functions. Until then, the GNU C Library may
provide them in the header file. When the GCC built-in functions
become available, those provided in the header file should be made
conditionally available prior to the GCC version in which the
built-in function was made available.
* If the header file provides features that are specific to an
operating system, both GCC and the GNU C Library could provide it,
but the GNU C Library is preferred as it already has a lot of
information about the operating system.
* If the header file provides features that are specific to an
operating system but used by the GNU C Library, then the GNU C
Library should provide them.
The general solution for providing low-level features is to export
them as follows:
* A nonstandard, low-level header file that defines macros and inline
functions should be called `sys/platform/NAME.h'.
* Each header file's name should include the platform name, to avoid
users thinking there is anything in common between different the
header files for different platforms. For example, a
`sys/platform/ARCH.h' name such as `sys/platform/ppc.h' is better
than `sys/platform.h'.
* A platform-specific header file provided by the GNU C Library
should coordinate with GCC such that compiler built-in versions of
the functions and macros are preferred if available. This means
that user programs will only ever need to include
`sys/platform/ARCH.h', keeping the same names of types, macros,
and functions for convenience and portability.
* Each included symbol must have the prefix `__ARCH_', such as
`__ppc_get_timebase'.
The easiest way to provide a header file is to add it to the
`sysdep_headers' variable. For example, the combination of
Linux-specific header files on PowerPC could be provided like this:
sysdep_headers += sys/platform/ppc.h
Then ensure that you have added a `sys/platform/ppc.h' header file
in the machine-specific directory, e.g.,
`sysdeps/powerpc/sys/platform/ppc.h'.

D.2 Porting the GNU C Library
=============================
The GNU C Library is written to be easily portable to a variety of
machines and operating systems. Machine- and operating system-dependent
functions are well separated to make it easy to add implementations for
new machines or operating systems. This section describes the layout of
the library source tree and explains the mechanisms used to select
machine-dependent code to use.
All the machine-dependent and operating system-dependent files in the
library are in the subdirectory `sysdeps' under the top-level library
source directory. This directory contains a hierarchy of
subdirectories (*note Hierarchy Conventions::).
Each subdirectory of `sysdeps' contains source files for a
particular machine or operating system, or for a class of machine or
operating system (for example, systems by a particular vendor, or all
machines that use IEEE 754 floating-point format). A configuration
specifies an ordered list of these subdirectories. Each subdirectory
implicitly appends its parent directory to the list. For example,
specifying the list `unix/bsd/vax' is equivalent to specifying the list
`unix/bsd/vax unix/bsd unix'. A subdirectory can also specify that it
implies other subdirectories which are not directly above it in the
directory hierarchy. If the file `Implies' exists in a subdirectory,
it lists other subdirectories of `sysdeps' which are appended to the
list, appearing after the subdirectory containing the `Implies' file.
Lines in an `Implies' file that begin with a `#' character are ignored
as comments. For example, `unix/bsd/Implies' contains:
# BSD has Internet-related things.
unix/inet
and `unix/Implies' contains:
posix
So the final list is `unix/bsd/vax unix/bsd unix/inet unix posix'.
`sysdeps' has a "special" subdirectory called `generic'. It is
always implicitly appended to the list of subdirectories, so you
needn't put it in an `Implies' file, and you should not create any
subdirectories under it intended to be new specific categories.
`generic' serves two purposes. First, the makefiles do not bother to
look for a system-dependent version of a file that's not in `generic'.
This means that any system-dependent source file must have an analogue
in `generic', even if the routines defined by that file are not
implemented on other platforms. Second, the `generic' version of a
system-dependent file is used if the makefiles do not find a version
specific to the system you're compiling for.
If it is possible to implement the routines in a `generic' file in
machine-independent C, using only other machine-independent functions in
the C library, then you should do so. Otherwise, make them stubs. A
"stub" function is a function which cannot be implemented on a
particular machine or operating system. Stub functions always return an
error, and set `errno' to `ENOSYS' (Function not implemented). *Note
Error Reporting::. If you define a stub function, you must place the
statement `stub_warning(FUNCTION)', where FUNCTION is the name of your
function, after its definition. This causes the function to be listed
in the installed `<gnu/stubs.h>', and makes GNU ld warn when the
function is used.
Some rare functions are only useful on specific systems and aren't
defined at all on others; these do not appear anywhere in the
system-independent source code or makefiles (including the `generic'
directory), only in the system-dependent `Makefile' in the specific
system's subdirectory.
If you come across a file that is in one of the main source
directories (`string', `stdio', etc.), and you want to write a machine-
or operating system-dependent version of it, move the file into
`sysdeps/generic' and write your new implementation in the appropriate
system-specific subdirectory. Note that if a file is to be
system-dependent, it *must not* appear in one of the main source
directories.
There are a few special files that may exist in each subdirectory of
`sysdeps':
`Makefile'
A makefile for this machine or operating system, or class of
machine or operating system. This file is included by the library
makefile `Makerules', which is used by the top-level makefile and
the subdirectory makefiles. It can change the variables set in the
including makefile or add new rules. It can use GNU `make'
conditional directives based on the variable `subdir' (see above)
to select different sets of variables and rules for different
sections of the library. It can also set the `make' variable
`sysdep-routines', to specify extra modules to be included in the
library. You should use `sysdep-routines' rather than adding
modules to `routines' because the latter is used in determining
what to distribute for each subdirectory of the main source tree.
Each makefile in a subdirectory in the ordered list of
subdirectories to be searched is included in order. Since several
system-dependent makefiles may be included, each should append to
`sysdep-routines' rather than simply setting it:
sysdep-routines := $(sysdep-routines) foo bar
`Subdirs'
This file contains the names of new whole subdirectories under the
top-level library source tree that should be included for this
system. These subdirectories are treated just like the
system-independent subdirectories in the library source tree, such
as `stdio' and `math'.
Use this when there are completely new sets of functions and header
files that should go into the library for the system this
subdirectory of `sysdeps' implements. For example,
`sysdeps/unix/inet/Subdirs' contains `inet'; the `inet' directory
contains various network-oriented operations which only make sense
to put in the library on systems that support the Internet.
`configure'
This file is a shell script fragment to be run at configuration
time. The top-level `configure' script uses the shell `.' command
to read the `configure' file in each system-dependent directory
chosen, in order. The `configure' files are often generated from
`configure.in' files using Autoconf.
A system-dependent `configure' script will usually add things to
the shell variables `DEFS' and `config_vars'; see the top-level
`configure' script for details. The script can check for
`--with-PACKAGE' options that were passed to the top-level
`configure'. For an option `--with-PACKAGE=VALUE' `configure'
sets the shell variable `with_PACKAGE' (with any dashes in PACKAGE
converted to underscores) to VALUE; if the option is just
`--with-PACKAGE' (no argument), then it sets `with_PACKAGE' to
`yes'.
`configure.in'
This file is an Autoconf input fragment to be processed into the
file `configure' in this subdirectory. *Note Introduction:
(autoconf.info)Introduction, for a description of Autoconf. You
should write either `configure' or `configure.in', but not both.
The first line of `configure.in' should invoke the `m4' macro
`GLIBC_PROVIDES'. This macro does several `AC_PROVIDE' calls for
Autoconf macros which are used by the top-level `configure'
script; without this, those macros might be invoked again
unnecessarily by Autoconf.
That is the general system for how system-dependencies are isolated.

D.2.1 Layout of the `sysdeps' Directory Hierarchy
-------------------------------------------------
A GNU configuration name has three parts: the CPU type, the
manufacturer's name, and the operating system. `configure' uses these
to pick the list of system-dependent directories to look for. If the
`--nfp' option is _not_ passed to `configure', the directory
`MACHINE/fpu' is also used. The operating system often has a "base
operating system"; for example, if the operating system is `Linux', the
base operating system is `unix/sysv'. The algorithm used to pick the
list of directories is simple: `configure' makes a list of the base
operating system, manufacturer, CPU type, and operating system, in that
order. It then concatenates all these together with slashes in
between, to produce a directory name; for example, the configuration
`i686-linux-gnu' results in `unix/sysv/linux/i386/i686'. `configure'
then tries removing each element of the list in turn, so
`unix/sysv/linux' and `unix/sysv' are also tried, among others. Since
the precise version number of the operating system is often not
important, and it would be very inconvenient, for example, to have
identical `irix6.2' and `irix6.3' directories, `configure' tries
successively less specific operating system names by removing trailing
suffixes starting with a period.
As an example, here is the complete list of directories that would be
tried for the configuration `i686-linux-gnu' (with the `crypt' and
`linuxthreads' add-on):
sysdeps/i386/elf
crypt/sysdeps/unix
linuxthreads/sysdeps/unix/sysv/linux
linuxthreads/sysdeps/pthread
linuxthreads/sysdeps/unix/sysv
linuxthreads/sysdeps/unix
linuxthreads/sysdeps/i386/i686
linuxthreads/sysdeps/i386
linuxthreads/sysdeps/pthread/no-cmpxchg
sysdeps/unix/sysv/linux/i386
sysdeps/unix/sysv/linux
sysdeps/gnu
sysdeps/unix/common
sysdeps/unix/mman
sysdeps/unix/inet
sysdeps/unix/sysv/i386/i686
sysdeps/unix/sysv/i386
sysdeps/unix/sysv
sysdeps/unix/i386
sysdeps/unix
sysdeps/posix
sysdeps/i386/i686
sysdeps/i386/i486
sysdeps/libm-i387/i686
sysdeps/i386/fpu
sysdeps/libm-i387
sysdeps/i386
sysdeps/wordsize-32
sysdeps/ieee754
sysdeps/libm-ieee754
sysdeps/generic
Different machine architectures are conventionally subdirectories at
the top level of the `sysdeps' directory tree. For example,
`sysdeps/sparc' and `sysdeps/m68k'. These contain files specific to
those machine architectures, but not specific to any particular
operating system. There might be subdirectories for specializations of
those architectures, such as `sysdeps/m68k/68020'. Code which is
specific to the floating-point coprocessor used with a particular
machine should go in `sysdeps/MACHINE/fpu'.
There are a few directories at the top level of the `sysdeps'
hierarchy that are not for particular machine architectures.
`generic'
As described above (*note Porting::), this is the subdirectory
that every configuration implicitly uses after all others.
`ieee754'
This directory is for code using the IEEE 754 floating-point
format, where the C type `float' is IEEE 754 single-precision
format, and `double' is IEEE 754 double-precision format. Usually
this directory is referred to in the `Implies' file in a machine
architecture-specific directory, such as `m68k/Implies'.
`libm-ieee754'
This directory contains an implementation of a mathematical library
usable on platforms which use IEEE 754 conformant floating-point
arithmetic.
`libm-i387'
This is a special case. Ideally the code should be in
`sysdeps/i386/fpu' but for various reasons it is kept aside.
`posix'
This directory contains implementations of things in the library in
terms of POSIX.1 functions. This includes some of the POSIX.1
functions themselves. Of course, POSIX.1 cannot be completely
implemented in terms of itself, so a configuration using just
`posix' cannot be complete.
`unix'
This is the directory for Unix-like things. *Note Porting to
Unix::. `unix' implies `posix'. There are some special-purpose
subdirectories of `unix':
`unix/common'
This directory is for things common to both BSD and System V
release 4. Both `unix/bsd' and `unix/sysv/sysv4' imply
`unix/common'.
`unix/inet'
This directory is for `socket' and related functions on Unix
systems. `unix/inet/Subdirs' enables the `inet' top-level
subdirectory. `unix/common' implies `unix/inet'.
`mach'
This is the directory for things based on the Mach microkernel
from CMU (including GNU/Hurd systems). Other basic operating
systems (VMS, for example) would have their own directories at the
top level of the `sysdeps' hierarchy, parallel to `unix' and
`mach'.

File: libc.info, Node: Porting to Unix, Prev: Hierarchy Conventions, Up: Porting
D.2.2 Porting the GNU C Library to Unix Systems
-----------------------------------------------
Most Unix systems are fundamentally very similar. There are variations
between different machines, and variations in what facilities are
provided by the kernel. But the interface to the operating system
facilities is, for the most part, pretty uniform and simple.
The code for Unix systems is in the directory `unix', at the top
level of the `sysdeps' hierarchy. This directory contains
subdirectories (and subdirectory trees) for various Unix variants.
The functions which are system calls in most Unix systems are
implemented in assembly code, which is generated automatically from
specifications in files named `syscalls.list'. There are several such
files, one in `sysdeps/unix' and others in its subdirectories. Some
special system calls are implemented in files that are named with a
suffix of `.S'; for example, `_exit.S'. Files ending in `.S' are run
through the C preprocessor before being fed to the assembler.
These files all use a set of macros that should be defined in
`sysdep.h'. The `sysdep.h' file in `sysdeps/unix' partially defines
them; a `sysdep.h' file in another directory must finish defining them
for the particular machine and operating system variant. See
`sysdeps/unix/sysdep.h' and the machine-specific `sysdep.h'
implementations to see what these macros are and what they should do.
The system-specific makefile for the `unix' directory
(`sysdeps/unix/Makefile') gives rules to generate several files from
the Unix system you are building the library on (which is assumed to be
the target system you are building the library _for_). All the
generated files are put in the directory where the object files are
kept; they should not affect the source tree itself. The files
generated are `ioctls.h', `errnos.h', `sys/param.h', and `errlist.c'
(for the `stdio' section of the library).

Appendix E Platform-specific facilities
***************************************
The GNU C Library can provide machine-specific functionality.
* Menu:
* PowerPC:: Facilities Specific to the PowerPC Architecture

File: libc.info, Node: PowerPC, Up: Platform
E.1 PowerPC-specific Facilities
===============================
Facilities specific to PowerPC that are not specific to a particular
operating system are declared in `sys/platform/ppc.h'.
-- Function: uint64_t __ppc_get_timebase (void)
Read the current value of the Time Base Register.
The "Time Base Register" is a 64-bit register that stores a
monotonically incremented value updated at a system-dependent
frequency that may be different from the processor frequency.
More information is available in `Power ISA 2.06b - Book II -
Section 5.2'.
`__ppc_get_timebase' uses the processor's time base facility
directly without requiring assistance from the operating system,
so it is very efficient.
-- Function: uint64_t __ppc_get_timebase_freq (void)
Read the current frequency at which the Time Base Register is
updated.
This frequency is not related to the processor clock or the bus
clock. It is also possible that this frequency is not constant.
More information is available in `Power ISA 2.06b - Book II -
Section 5.2'.
The following functions provide hints about the usage of resources
that are shared with other processors. They can be used, for example,
if a program waiting on a lock intends to divert the shared resources
to be used by other processors. More information is available in
`Power ISA 2.06b - Book II - Section 3.2'.
-- Function: void __ppc_yield (void)
Provide a hint that performance will probably be improved if
shared resources dedicated to the executing processor are released
for use by other processors.
-- Function: void __ppc_mdoio (void)
Provide a hint that performance will probably be improved if
shared resources dedicated to the executing processor are released
until all outstanding storage accesses to caching-inhibited
storage have been completed.
-- Function: void __ppc_mdoom (void)
Provide a hint that performance will probably be improved if
shared resources dedicated to the executing processor are released
until all outstanding storage accesses to cacheable storage for
which the data is not in the cache have been completed.
-- Function: void __ppc_set_ppr_med (void)
Set the Program Priority Register to medium value (default).
The "Program Priority Register" (PPR) is a 64-bit register that
controls the program's priority. By adjusting the PPR value the
programmer may improve system throughput by causing the system
resources to be used more efficiently, especially in contention
situations. The three unprivileged states available are covered
by the functions `__ppc_set_ppr_med' (medium - default),
`__ppc_set_ppc_low' (low) and `__ppc_set_ppc_med_low' (medium
low). More information available in `Power ISA 2.06b - Book II -
Section 3.1'.
-- Function: void __ppc_set_ppr_low (void)
Set the Program Priority Register to low value.
-- Function: void __ppc_set_ppr_med_low (void)
Set the Program Priority Register to medium low value.

Appendix G Free Software Needs Free Documentation
*************************************************
The biggest deficiency in the free software community today is not in
the software--it is the lack of good free documentation that we can
include with the free software. Many of our most important programs do
not come with free reference manuals and free introductory texts.
Documentation is an essential part of any software package; when an
important free software package does not come with a free manual and a
free tutorial, that is a major gap. We have many such gaps today.
Consider Perl, for instance. The tutorial manuals that people
normally use are non-free. How did this come about? Because the
authors of those manuals published them with restrictive terms--no
copying, no modification, source files not available--which exclude
them from the free software world.
That wasn't the first time this sort of thing happened, and it was
far from the last. Many times we have heard a GNU user eagerly
describe a manual that he is writing, his intended contribution to the
community, only to learn that he had ruined everything by signing a
publication contract to make it non-free.
Free documentation, like free software, is a matter of freedom, not
price. The problem with the non-free manual is not that publishers
charge a price for printed copies--that in itself is fine. (The Free
Software Foundation sells printed copies of manuals, too.) The problem
is the restrictions on the use of the manual. Free manuals are
available in source code form, and give you permission to copy and
modify. Non-free manuals do not allow this.
The criteria of freedom for a free manual are roughly the same as for
free software. Redistribution (including the normal kinds of
commercial redistribution) must be permitted, so that the manual can
accompany every copy of the program, both on-line and on paper.
Permission for modification of the technical content is crucial too.
When people modify the software, adding or changing features, if they
are conscientious they will change the manual too--so they can provide
accurate and clear documentation for the modified program. A manual
that leaves you no choice but to write a new manual to document a
changed version of the program is not really available to our community.
Some kinds of limits on the way modification is handled are
acceptable. For example, requirements to preserve the original
author's copyright notice, the distribution terms, or the list of
authors, are ok. It is also no problem to require modified versions to
include notice that they were modified. Even entire sections that may
not be deleted or changed are acceptable, as long as they deal with
nontechnical topics (like this one). These kinds of restrictions are
acceptable because they don't obstruct the community's normal use of
the manual.
However, it must be possible to modify all the _technical_ content
of the manual, and then distribute the result in all the usual media,
through all the usual channels. Otherwise, the restrictions obstruct
the use of the manual, it is not free, and we need another manual to
replace it.
Please spread the word about this issue. Our community continues to
lose manuals to proprietary publishing. If we spread the word that
free software needs free reference manuals and free tutorials, perhaps
the next person who wants to contribute by writing documentation will
realize, before it is too late, that only free manuals contribute to
the free software community.
If you are writing documentation, please insist on publishing it
under the GNU Free Documentation License or another free documentation
license. Remember that this decision requires your approval--you don't
have to let the publisher decide. Some commercial publishers will use
a free license if you insist, but they will not propose the option; it
is up to you to raise the issue and say firmly that this is what you
want. If the publisher you are dealing with refuses, please try other
publishers. If you're not sure whether a proposed license is free,
write to <licensing@gnu.org>.
You can encourage commercial publishers to sell more free, copylefted
manuals and tutorials by buying them, and particularly by buying copies
from the publishers that paid for their writing or for major
improvements. Meanwhile, try to avoid buying non-free documentation at
all. Check the distribution terms of a manual before you buy it, and
insist that whoever seeks your business must respect your freedom.
Check the history of the book, and try reward the publishers that have
paid or pay the authors to work on it.

published by other publishers, at

Appendix H GNU Lesser General Public License
********************************************
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence the
version number 2.1.]
Preamble
--------
The licenses for most software are designed to take away your freedom
to share and change it. By contrast, the GNU General Public Licenses
are intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software--typically libraries--of the Free
Software Foundation and other authors who decide to use it. You can use
it too, but we suggest you first think carefully about whether this
license or the ordinary General Public License is the better strategy to
use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of it
in new free programs; and that you are informed that you can do these
things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know that
what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and is
quite different from the ordinary General Public License. We use this
license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does _Less_ to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it
becomes a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of free
software. For example, permission to use the GNU C Library in non-free
programs enables many more people to use the whole GNU operating
system, as well as its variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run that
program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
---------------------------------------------------------------
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the
terms of this Lesser General Public License (also called "this
License"). Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or
translated straightforwardly into another language. (Hereinafter,
translation is included without limitation in the term
"modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code
means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the library.
Activities other than copying, distribution and modification are
not covered by this License; they are outside its scope. The act
of running a program using the Library is not restricted, and
output from such a program is covered only if its contents
constitute a work based on the Library (independent of the use of
the Library in a tool for writing it). Whether that is true
depends on what the Library does and what the program that uses
the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided
that you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep
intact all the notices that refer to this License and to the
absence of any warranty; and distribute a copy of this License
along with the Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange
for a fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a. The modified work must itself be a software library.
b. You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c. You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d. If a facility in the modified Library refers to a function or
a table of data to be supplied by an application program that
uses the facility, other than as an argument passed when the
facility is invoked, then you must make a good faith effort
to ensure that, in the event an application does not supply
such function or table, the facility still operates, and
performs whatever part of its purpose remains meaningful.
(For example, a function in a library to compute square roots
has a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function
must be optional: if the application does not supply it, the
square root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the
Library, and can be reasonably considered independent and separate
works in themselves, then this License, and its terms, do not
apply to those sections when you distribute them as separate
works. But when you distribute the same sections as part of a
whole which is a work based on the Library, the distribution of
the whole must be on the terms of this License, whose permissions
for other licensees extend to the entire whole, and thus to each
and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or
contest your rights to work written entirely by you; rather, the
intent is to exercise the right to control the distribution of
derivative or collective works based on the Library.
In addition, mere aggregation of another work not based on the
Library with the Library (or with a work based on the Library) on
a volume of a storage or distribution medium does not bring the
other work under the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library.
To do this, you must alter all the notices that refer to this
License, so that they refer to the ordinary GNU General Public
License, version 2, instead of to this License. (If a newer
version than version 2 of the ordinary GNU General Public License
has appeared, then you can specify that version instead if you
wish.) Do not make any other change in these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to
all subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable
form under the terms of Sections 1 and 2 above provided that you
accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software
interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy
the source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being
compiled or linked with it, is called a "work that uses the
Library". Such a work, in isolation, is not a derivative work of
the Library, and therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because
it contains portions of the Library), rather than a "work that
uses the library". The executable is therefore covered by this
License. Section 6 states terms for distribution of such
executables.
When a "work that uses the Library" uses material from a header
file that is part of the Library, the object code for the work may
be a derivative work of the Library even though the source code is
not. Whether this is true is especially significant if the work
can be linked without the Library, or if the work is itself a
library. The threshold for this to be true is not precisely
defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a
derivative work. (Executables containing this object code plus
portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section
6. Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered
by this License. You must supply a copy of this License. If the
work during execution displays copyright notices, you must include
the copyright notice for the Library among them, as well as a
reference directing the user to the copy of this License. Also,
you must do one of these things:
a. Accompany the work with the complete corresponding
machine-readable source code for the Library including
whatever changes were used in the work (which must be
distributed under Sections 1 and 2 above); and, if the work
is an executable linked with the Library, with the complete
machine-readable "work that uses the Library", as object code
and/or source code, so that the user can modify the Library
and then relink to produce a modified executable containing
the modified Library. (It is understood that the user who
changes the contents of definitions files in the Library will
not necessarily be able to recompile the application to use
the modified definitions.)
b. Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run
time a copy of the library already present on the user's
computer system, rather than copying library functions into
the executable, and (2) will operate properly with a modified
version of the library, if the user installs one, as long as
the modified version is interface-compatible with the version
that the work was made with.
c. Accompany the work with a written offer, valid for at least
three years, to give the same user the materials specified in
Subsection 6a, above, for a charge no more than the cost of
performing this distribution.
d. If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the
above specified materials from the same place.
e. Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special
exception, the materials to be distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of
the operating system on which the executable runs, unless that
component itself accompanies the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you
cannot use both them and the Library together in an executable
that you distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other
library facilities not covered by this License, and distribute
such a combined library, provided that the separate distribution
of the work based on the Library and of the other library
facilities is otherwise permitted, and provided that you do these
two things:
a. Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b. Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same
work.
8. You may not copy, modify, sublicense, link with, or distribute the
Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate
your rights under this License. However, parties who have
received copies, or rights, from you under this License will not
have their licenses terminated so long as such parties remain in
full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify
or distribute the Library or its derivative works. These actions
are prohibited by law if you do not accept this License.
Therefore, by modifying or distributing the Library (or any work
based on the Library), you indicate your acceptance of this
License to do so, and all its terms and conditions for copying,
distributing or modifying the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the
Library subject to these terms and conditions. You may not impose
any further restrictions on the recipients' exercise of the rights
granted herein. You are not responsible for enforcing compliance
by third parties with this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent
issues), conditions are imposed on you (whether by court order,
agreement or otherwise) that contradict the conditions of this
License, they do not excuse you from the conditions of this
License. If you cannot distribute so as to satisfy simultaneously
your obligations under this License and any other pertinent
obligations, then as a consequence you may not distribute the
Library at all. For example, if a patent license would not permit
royalty-free redistribution of the Library by all those who
receive copies directly or indirectly through you, then the only
way you could satisfy both it and this License would be to refrain
entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable
under any particular circumstance, the balance of the section is
intended to apply, and the section as a whole is intended to apply
in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of
any such claims; this section has the sole purpose of protecting
the integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is
willing to distribute software through any other system and a
licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed
to be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces,
the original copyright holder who places the Library under this
License may add an explicit geographical distribution limitation
excluding those countries, so that distribution is permitted only
in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of
this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public 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.
Each version is given a distinguishing version number. If the
Library specifies a version number of this License which applies
to it and "any later version", you have the option of following
the terms and conditions either of that version or of any later
version published by the Free Software Foundation. If the Library
does not specify a license version number, you may choose any
version ever published by the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free
status of all derivatives of our free software and of promoting
the sharing and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE
LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE
LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY
OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
---------------------------
How to Apply These Terms to Your New Libraries
----------------------------------------------
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of
the ordinary General Public License).
To apply these terms, attach the following notices to the library.
It is safest to attach them to the start of each source file to most
effectively convey the exclusion of warranty; and each file should have
at least the "copyright" line and a pointer to where the full notice is
found.
ONE LINE TO GIVE THE LIBRARY'S NAME AND AN IDEA OF WHAT IT DOES.
Copyright (C) YEAR NAME OF AUTHOR
This library is free software; you can redistribute it and/or modify it
under the terms of the GNU Lesser General Public License as published by
the Free Software Foundation; either version 2.1 of the License, or (at
your option) any later version.
This library is distributed in the hope that it will be useful, but
WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU

You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301,
USA.
Also add information on how to contact you by electronic and paper
mail.
You should also get your employer (if you work as a programmer) or
your school, if any, to sign a "copyright disclaimer" for the library,
if necessary. Here is a sample; alter the names:

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
`http://www.gnu.org/copyleft/'.
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.
