<p>Copyright (C) 1991, 1999 Free Software Foundation, Inc.<br>

Everyone is permitted to copy and distribute verbatim copies<br>
|
|
of this license document, but changing it is not allowed.</p>
|
|
<p>[This is the first released version of the Lesser GPL. It also counts<br>
|
|
as the successor of the GNU Library Public License, version 2, hence<br>
|
|
the version number 2.1.]</p>
|
|
<p>Preamble<br>
|
|
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. </p>
|
|
<p>This license, the Lesser General Public License, applies to some specially
|
|
designated software packages--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. </p>
|
|
<p>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.</p>
|
|
<p>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. </p>
|
|
<p>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.
|
|
</p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION<br>
|
|
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".</p>
|
|
<p>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. </p>
|
|
<p>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".)
|
|
</p>
|
|
<p>"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.</p>
|
|
<p>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. </p>
|
|
<p>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.
|
|
</p>
|
|
<p>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. </p>
|
|
<p>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: </p>
|
|
<p>a) The modified work must itself be a software library. </p>
|
|
<p>b) You must cause the files modified to carry prominent notices stating that
|
|
you changed the files and the date of any change.</p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>(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.) </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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.
|
|
</p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>This option is useful when you wish to copy part of the code of the Library
|
|
into a program that is not a library. </p>
|
|
<p>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. </p>
|
|
<p>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.</p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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.) </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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: </p>
|
|
<p>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.) </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>e) Verify that the user has already received a copy of these materials or that
|
|
you have already sent this user a copy.</p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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: </p>
|
|
<p>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. </p>
|
|
<p>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.</p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>This section is intended to make thoroughly clear what is believed to be a
|
|
consequence of the rest of this License. </p>
|
|
<p>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. </p>
|
|
<p>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.</p>
|
|
<p>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. </p>
|
|
<p>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. </p>
|
|
<p>NO WARRANTY </p>
|
|
<p>15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
