<h2 id="preamble"><a class="header" href="#preamble">Preamble</a></h2>
|
|
<p>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>
|
|
<h2 id="terms-and-conditions-for-copying-distribution-and-modification"><a class="header" href="#terms-and-conditions-for-copying-distribution-and-modification">TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</a></h2>
|
|
<p><strong>0.</strong> 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><strong>1.</strong> 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><strong>2.</strong> 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>
|
|
<ul>
|
|
<li>
|
|
<p><strong>a)</strong> The modified work must itself be a software library.</p>
|
|
</li>
|
|
<li>
|
|
<p><strong>b)</strong> You must cause the files modified to carry prominent
|
|
notices stating that you changed the files and the date of
|
|
any change.</p>
|
|
</li>
|
|
<li>
|
|
<p><strong>c)</strong> 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>
|
|
</li>
|
|
<li>
|
|
<p><strong>d)</strong> 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>
|
|
</li>
|
|
</ul>
|
|
<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><strong>3.</strong> 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><strong>4.</strong> 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><strong>5.</strong> 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><strong>6.</strong> 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>
|
|
<ul>
|
|
<li><strong>a)</strong> 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.)</li>
|
|
<li><strong>b)</strong> 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.</li>
|
|
<li><strong>c)</strong> 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.</li>
|
|
<li><strong>d)</strong> 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.</li>
|
|
<li><strong>e)</strong> Verify that the user has already received a copy of these
|
|
materials or that you have already sent this user a copy.</li>
|
|
</ul>
|
|
<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><strong>7.</strong> 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>
|
|
<ul>
|
|
<li><strong>a)</strong> 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.</li>
|
|
<li><strong>b)</strong> 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.</li>
|
|
</ul>
|
|
<p><strong>8.</strong> 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><strong>9.</strong> 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><strong>10.</strong> 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><strong>11.</strong> 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><strong>12.</strong> 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><strong>13.</strong> 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><strong>14.</strong> 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><strong>NO WARRANTY</strong></p>
|
|
<p><strong>15.</strong> 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.</p>
|
|
<p><strong>16.</strong> 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.</p>

<p>END OF TERMS AND CONDITIONS</p>

|
|
<p>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).</p>
|
|
<p>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.</p>
|
|
<pre><code>one line to give the library's name and an idea of what it does.
