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.

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. 
+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.

-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.

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.

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

 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".

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".)

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

at your option offer warranty protection in exchange for a fee.

modifications or work under the terms of Section 1 above, provided that you 
also meet all of these conditions: 
+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.) 
+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.

-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.

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.

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.

-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

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.

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.)

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. 
+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.

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.

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.

 How to Apply These Terms to Your New Libraries

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

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.
