The complete text of the Eclipse Public License is as follows:

Eclipse Public License - v 1.0

THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE

PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION

OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.

1. DEFINITIONS

"Contribution" means:

a) in the case of the initial Contributor, the initial code and

documentation distributed under this Agreement, and

b) in the case of each subsequent Contributor:

i) changes to the Program, and

ii) additions to the Program;

where such changes and/or additions to the Program

originate from and are distributed by that particular

Contributor. A Contribution 'originates' from a

Contributor if it was added to the Program by such

Contributor itself or anyone acting on such

Contributor's behalf. Contributions do not include

additions to the Program which: (i) are separate modules

of software distributed in conjunction with the Program

under their own license agreement, and (ii) are not

derivative works of the Program.

"Contributor" means any person or entity that distributes the Program.

"Licensed Patents" mean patent claims licensable by a Contributor

which are necessarily infringed by the use or sale of its

Contribution alone or when combined with the Program.

"Program" means the Contributions distributed in accordance with

this Agreement.

"Recipient" means anyone who receives the Program under this

Agreement, including all Contributors.

2. GRANT OF RIGHTS

a) Subject to the terms of this Agreement, each Contributor

hereby grants Recipient a non-exclusive, worldwide,

royalty-free copyright license to reproduce, prepare

derivative works of, publicly display, publicly perform,

distribute and sublicense the Contribution of such

Contributor, if any, and such derivative works, in source

code and object code form.

b) Subject to the terms of this Agreement, each Contributor

hereby grants Recipient a non-exclusive, worldwide,

royalty-free patent license under Licensed Patents to make,

use, sell, offer to sell, import and otherwise transfer the

Contribution of such Contributor, if any, in source code and

object code form. This patent license shall apply to the

combination of the Contribution and the Program if, at the

time the Contribution is added by the Contributor, such

addition of the Contribution causes such combination to be

covered by the Licensed Patents. The patent license shall not

apply to any other combinations which include the

Contribution. No hardware per se is licensed hereunder.

c) Recipient understands that although each Contributor grants

the licenses to its Contributions set forth herein, no

assurances are provided by any Contributor that the Program

does not infringe the patent or other intellectual property

rights of any other entity. Each Contributor disclaims any

liability to Recipient for claims brought by any other entity

based on infringement of intellectual property rights or

otherwise. As a condition to exercising the rights and

licenses granted hereunder, each Recipient hereby assumes

sole responsibility to secure any other intellectual property

rights needed, if any. For example, if a third party patent

license is required to allow Recipient to distribute the

Program, it is Recipient's responsibility to acquire that

license before distributing the Program.

d) Each Contributor represents that to its knowledge it has

sufficient copyright rights in its Contribution, if any, to

grant the copyright license set forth in this Agreement.

3. REQUIREMENTS

A Contributor may choose to distribute the Program in object code

form under its own license agreement, provided that:

a) it complies with the terms and conditions of this Agreement; and

b) its license agreement:

i) effectively disclaims on behalf of all Contributors all

warranties and conditions, express and implied, including

warranties or conditions of title and non-infringement,

and implied warranties or conditions of merchantability

and fitness for a particular purpose;

ii) effectively excludes on behalf of all Contributors all

liability for damages, including direct, indirect,

special, incidental and consequential damages, such as

lost profits;

iii) states that any provisions which differ from this

Agreement are offered by that Contributor alone and not

by any other party; and

iv) states that source code for the Program is available

from such Contributor, and informs licensees how to

obtain it in a reasonable manner on or through a medium

customarily used for software exchange.

When the Program is made available in source code form:

a) it must be made available under this Agreement; and

b) a copy of this Agreement must be included with each copy of

the Program.

Contributors may not remove or alter any copyright notices contained

within the Program.

Each Contributor must identify itself as the originator of its

Contribution, if any, in a manner that reasonably allows subsequent

Recipients to identify the originator of the Contribution.

4. COMMERCIAL DISTRIBUTION

Commercial distributors of software may accept certain

responsibilities with respect to end users, business partners and

the like. While this license is intended to facilitate the

commercial use of the Program, the Contributor who includes the

Program in a commercial product offering should do so in a manner

which does not create potential liability for other Contributors.

Therefore, if a Contributor includes the Program in a commercial

product offering, such Contributor ("Commercial Contributor") hereby

agrees to defend and indemnify every other Contributor ("Indemnified

Contributor") against any losses, damages and costs (collectively

"Losses") arising from claims, lawsuits and other legal actions

brought by a third party against the Indemnified Contributor to the

extent caused by the acts or omissions of such Commercial

Contributor in connection with its distribution of the Program in a

commercial product offering. The obligations in this section do not

apply to any claims or Losses relating to any actual or alleged

intellectual property infringement. In order to qualify, an

Indemnified Contributor must: a) promptly notify the Commercial

Contributor in writing of such claim, and b) allow the Commercial

Contributor to control, and cooperate with the Commercial

Contributor in, the defense and any related settlement negotiations.

The Indemnified Contributor may participate in any such claim at its

own expense.

For example, a Contributor might include the Program in a commercial

product offering, Product X. That Contributor is then a Commercial

Contributor. If that Commercial Contributor then makes performance

claims, or offers warranties related to Product X, those performance

claims and warranties are such Commercial Contributor's

responsibility alone. Under this section, the Commercial Contributor

would have to defend claims against the other Contributors related

to those performance claims and warranties, and if a court requires

any other Contributor to pay any damages as a result, the Commercial

Contributor must pay those damages.

5. NO WARRANTY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS

PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF

ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION,

ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT,

MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient

is solely responsible for determining the appropriateness of using

and distributing the Program and assumes all risks associated with

its exercise of rights under this Agreement , including but not

limited to the risks and costs of program errors, compliance with

applicable laws, damage to or loss of data, programs or equipment,

and unavailability or interruption of operations.

6. DISCLAIMER OF LIABILITY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT

NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT,

INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES

(INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON

ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR

TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF

THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS

GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH

DAMAGES.

7. GENERAL

If any provision of this Agreement is invalid or unenforceable under

applicable law, it shall not affect the validity or enforceability

of the remainder of the terms of this Agreement, and without further

action by the parties hereto, such provision shall be reformed to

the minimum extent necessary to make such provision valid and

enforceable.

If Recipient institutes patent litigation against any entity

(including a cross-claim or counterclaim in a lawsuit) alleging that

the Program itself (excluding combinations of the Program with other

software or hardware) infringes such Recipient's patent(s), then

such Recipient's rights granted under Section 2(b) shall terminate

as of the date such litigation is filed.

All Recipient's rights under this Agreement shall terminate if it

fails to comply with any of the material terms or conditions of this

Agreement and does not cure such failure in a reasonable period of

time after becoming aware of such noncompliance. If all Recipient's

rights under this Agreement terminate, Recipient agrees to cease use

and distribution of the Program as soon as reasonably practicable.

However, Recipient's obligations under this Agreement and any

licenses granted by Recipient relating to the Program shall continue

and survive.

Everyone is permitted to copy and distribute copies of this

Agreement, but in order to avoid inconsistency the Agreement is

copyrighted and may only be modified in the following manner. The

Agreement Steward reserves the right to publish new versions

(including revisions) of this Agreement from time to time. No one

other than the Agreement Steward has the right to modify this

Agreement. The Eclipse Foundation is the initial Agreement Steward.

The Eclipse Foundation may assign the responsibility to serve as the

Agreement Steward to a suitable separate entity. Each new version of

the Agreement will be given a distinguishing version number. The

Program (including Contributions) may always be distributed subject

to the version of the Agreement under which it was received. In

addition, after a new version of the Agreement is published,

Contributor may elect to distribute the Program (including its

Contributions) under the new version. Except as expressly stated in

Sections 2(a) and 2(b) above, Recipient receives no rights or

licenses to the intellectual property of any Contributor under this

Agreement, whether expressly, by implication, estoppel or otherwise.

All rights in the Program not expressly granted under this Agreement

are reserved.

This Agreement is governed by the laws of the State of New York and

the intellectual property laws of the United States of America. No

party to this Agreement will bring a legal action under this

Agreement more than one year after the cause of action arose. Each

party waives its rights to a jury trial in any resulting litigation.

The complete text of the Common Public License is as follows:

Common Public License - v 1.0

THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS COMMON

PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF

THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.

where such changes and/or additions to the Program originate

from and are distributed by that particular Contributor. A

Contribution 'originates' from a Contributor if it was added to the

Program by such Contributor itself or anyone acting on such

Contributor's behalf. Contributions do not include additions to the

Program which: (i) are separate modules of software distributed in

conjunction with the Program under their own license agreement,

and (ii) are not derivative works of the Program.

"Contributor" means any person or entity that distributes the Program.

"Licensed Patents " mean patent claims licensable by a Contributor

which are necessarily infringed by the use or sale of its Contribution

alone or when combined with the Program.

"Program" means the Contributions distributed in accordance with this Agreement.

"Recipient" means anyone who receives the Program under this

Agreement, including all Contributors.

2. GRANT OF RIGHTS

a) Subject to the terms of this Agreement, each Contributor

hereby grants Recipient a non-exclusive, worldwide, royalty-free

copyright license to reproduce, prepare derivative works of, publicly

display, publicly perform, distribute and sublicense the Contribution

of such Contributor, if any, and such derivative works, in source code

and object code form.

b) Subject to the terms of this Agreement, each Contributor

hereby grants Recipient a non-exclusive, worldwide, royalty-free

patent license under Licensed Patents to make, use, sell, offer to

sell, import and otherwise transfer the Contribution of such

Contributor, if any, in source code and object code form. This patent

license shall apply to the combination of the Contribution and the

Program if, at the time the Contribution is added by the Contributor,

such addition of the Contribution causes such combination to be

covered by the Licensed Patents. The patent license shall not apply to

any other combinations which include the Contribution. No hardware per

se is licensed hereunder.

c) Recipient understands that although each Contributor grants

the licenses to its Contributions set forth herein, no assurances are

provided by any Contributor that the Program does not infringe the

patent or other intellectual property rights of any other entity. Each

Contributor disclaims any liability to Recipient for claims brought by

any other entity based on infringement of intellectual property rights

or otherwise. As a condition to exercising the rights and licenses

granted hereunder, each Recipient hereby assumes sole responsibility

to secure any other intellectual property rights needed, if any. For

example, if a third party patent license is required to allow

Recipient to distribute the Program, it is Recipient's responsibility

to acquire that license before distributing the Program.

d) Each Contributor represents that to its knowledge it has

sufficient copyright rights in its Contribution, if any, to grant the

copyright license set forth in this Agreement.

3. REQUIREMENTS

A Contributor may choose to distribute the Program in object code form

under its own license agreement, provided that:

a) it complies with the terms and conditions of this Agreement;

and

b) its license agreement:

i) effectively disclaims on behalf of all Contributors all

warranties and conditions, express and implied, including warranties

or conditions of title and non-infringement, and implied warranties or

conditions of merchantability and fitness for a particular purpose;

ii) effectively excludes on behalf of all Contributors all

liability for damages, including direct, indirect, special, incidental

and consequential damages, such as lost profits;

iii) states that any provisions which differ from this Agreement

are offered by that Contributor alone and not by any other party; and

iv) states that source code for the Program is available from

such Contributor, and informs licensees how to obtain it in a

reasonable manner on or through a medium customarily used for software

exchange.

When the Program is made available in source code form:

a) it must be made available under this Agreement; and

b) a copy of this Agreement must be included with each copy of

the Program.

Contributors may not remove or alter any copyright notices contained

within the Program.

Each Contributor must identify itself as the originator of its

Contribution, if any, in a manner that reasonably allows subsequent

Recipients to identify the originator of the Contribution.

4. COMMERCIAL DISTRIBUTION

Commercial distributors of software may accept certain

responsibilities with respect to end users, business partners and the

like. While this license is intended to facilitate the commercial use

of the Program, the Contributor who includes the Program in a

commercial product offering should do so in a manner which does not

create potential liability for other Contributors. Therefore, if a

Contributor includes the Program in a commercial product offering,

such Contributor ("Commercial Contributor") hereby agrees to defend

and indemnify every other Contributor ("Indemnified Contributor")

against any losses, damages and costs (collectively "Losses") arising

from claims, lawsuits and other legal actions brought by a third party

against the Indemnified Contributor to the extent caused by the acts

or omissions of such Commercial Contributor in connection with its

distribution of the Program in a commercial product offering. The

obligations in this section do not apply to any claims or Losses

relating to any actual or alleged intellectual property

infringement. In order to qualify, an Indemnified Contributor must: a)

promptly notify the Commercial Contributor in writing of such claim,

and b) allow the Commercial Contributor to control, and cooperate with

the Commercial Contributor in, the defense and any related settlement

negotiations. The Indemnified Contributor may participate in any such

claim at its own expense.

For example, a Contributor might include the Program in a commercial

product offering, Product X. That Contributor is then a Commercial

Contributor. If that Commercial Contributor then makes performance

claims, or offers warranties related to Product X, those performance

claims and warranties are such Commercial Contributor's responsibility

alone. Under this section, the Commercial Contributor would have to

defend claims against the other Contributors related to those

performance claims and warranties, and if a court requires any other

Contributor to pay any damages as a result, the Commercial Contributor

must pay those damages.

5. NO WARRANTY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS

PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY

KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY

WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY

OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely

responsible for determining the appropriateness of using and

distributing the Program and assumes all risks associated with its

exercise of rights under this Agreement, including but not limited to

the risks and costs of program errors, compliance with applicable

laws, damage to or loss of data, programs or equipment, and

unavailability or interruption of operations.

6. DISCLAIMER OF LIABILITY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR

ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,

INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING

WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF

LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING

NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR

DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED

HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

7. GENERAL

If any provision of this Agreement is invalid or unenforceable under

applicable law, it shall not affect the validity or enforceability of

the remainder of the terms of this Agreement, and without further

action by the parties hereto, such provision shall be reformed to the

minimum extent necessary to make such provision valid and enforceable.

If Recipient institutes patent litigation against a Contributor with

respect to a patent applicable to software (including a cross-claim or

counterclaim in a lawsuit), then any patent licenses granted by that

Contributor to such Recipient under this Agreement shall terminate as

of the date such litigation is filed. In addition, if Recipient

institutes patent litigation against any entity (including a

cross-claim or counterclaim in a lawsuit) alleging that the Program

itself (excluding combinations of the Program with other software or

hardware) infringes such Recipient's patent(s), then such Recipient's

rights granted under Section 2(b) shall terminate as of the date such

litigation is filed.

All Recipient's rights under this Agreement shall terminate if it

fails to comply with any of the material terms or conditions of this

Agreement and does not cure such failure in a reasonable period of

time after becoming aware of such noncompliance. If all Recipient's

rights under this Agreement terminate, Recipient agrees to cease use

and distribution of the Program as soon as reasonably

any licenses granted by Recipient relating to the Program shall

continue and survive.

Everyone is permitted to copy and distribute copies of this Agreement,

but in order to avoid inconsistency the Agreement is copyrighted and

may only be modified in the following manner. The Agreement Steward

reserves the right to publish new versions (including revisions) of

this Agreement from time to time. No one other than the Agreement

Steward has the right to modify this Agreement. IBM is the initial

Agreement Steward. IBM may assign the responsibility to serve as the

Agreement Steward to a suitable separate entity. Each new version of

the Agreement will be given a distinguishing version number. The

Program (including Contributions) may always be distributed subject to

the version of the Agreement under which it was received. In addition,

after a new version of the Agreement is published, Contributor may

elect to distribute the Program (including its Contributions) under

the new version. Except as expressly stated in Sections 2(a) and 2(b)

above, Recipient receives no rights or licenses to the intellectual

expressly granted under this Agreement are reserved.

This Agreement is governed by the laws of the State of New York and

The complete text of the GNU General Public License v2 is as follows:

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.

59 Temple Place, Suite 330, Boston, MA 02111-1307 USA

Everyone is permitted to copy and distribute verbatim copies

of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your

freedom to share and change it. By contrast, the GNU General Public

License is intended to guarantee your freedom to share and change free

software--to make sure the software is free for all its users. This

General Public License applies to most of the Free Software

Foundation's software and to any other program whose authors commit to

using it. (Some other Free Software Foundation software is covered by

the GNU Library General Public License instead.) You can apply it to

your programs, too.

When we speak of free software, we are referring to freedom, 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 or use pieces of it

in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid

anyone to deny you these rights or to ask you to surrender the rights.

These restrictions translate to certain responsibilities for you if you

distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether

gratis or for a fee, you must give the recipients all the rights that

you have. You must make sure that they, too, receive or can get the

source code. And you must show them these terms so they know their

rights.

We protect your rights with two steps: (1) copyright the software, and

(2) offer you this license which gives you legal permission to copy,

distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain

that everyone understands that there is no warranty for this free

software. If the software is modified by someone else and passed on, we

want its recipients to know that what they have is not the original, so

that any problems introduced by others will not reflect on the original

authors' reputations.

Finally, any free program is threatened constantly by software

patents. We wish to avoid the danger that redistributors of a free

program will individually obtain patent licenses, in effect making the

program proprietary. To prevent this, we have made it clear that any

patent must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and

modification follow.



GNU GENERAL PUBLIC LICENSE

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program or other work which contains

a notice placed by the copyright holder saying it may be distributed

under the terms of this General Public License. The "Program", below,

refers to any such program or work, and a "work based on the Program"

means either the Program or any derivative work under copyright law:

that is to say, a work containing the Program or a portion of it,

either verbatim or with modifications and/or translated into another

language. (Hereinafter, translation is included without limitation in

the term "modification".) Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not

covered by this License; they are outside its scope. The act of

running the Program is not restricted, and the output from the Program

is covered only if its contents constitute a work based on the

Program (independent of having been made by running the Program).

Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's

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 give any other recipients of the Program a copy of this License

along with the Program.

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 Program or any portion

of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices

stating that you changed the files and the date of any change.

b) You must cause any work that you distribute or publish, that in

whole or in part contains or is derived from the Program or any

part thereof, to be licensed as a whole at no charge to all third

parties under the terms of this License.

c) If the modified program normally reads commands interactively

when run, you must cause it, when started running for such

interactive use in the most ordinary way, to print or display an

announcement including an appropriate copyright notice and a

notice that there is no warranty (or else, saying that you provide

a warranty) and that users may redistribute the program under

these conditions, and telling the user how to view a copy of this

License. (Exception: if the Program itself is interactive but

does not normally print such an announcement, your work based on

the Program is not required to print an announcement.)



These requirements apply to the modified work as a whole. If

identifiable sections of that work are not derived from the Program,

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 Program, 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 Program.

In addition, mere aggregation of another work not based on the Program

with the Program (or with a work based on the Program) on a volume of

a storage or distribution medium does not bring the other work under

the scope of this License.

3. You may copy and distribute the Program (or a work based on it,

under Section 2) in object code or executable form under the terms of

Sections 1 and 2 above provided that you also do one of the following:

a) 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; or,

b) Accompany it with a written offer, valid for at least three

years, to give any third party, for a charge no more than your

cost of physically performing source distribution, a complete

machine-readable copy of the corresponding source code, to be

distributed under the terms of Sections 1 and 2 above on a medium

customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer

to distribute corresponding source code. (This alternative is

allowed only for noncommercial distribution and only if you

received the program in object code or executable form with such

an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for

making modifications to it. For an executable work, 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 executable. However, as a

special exception, the source code 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.

If distribution of executable or 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 counts as

distribution of the source code, even though third parties are not

compelled to copy the source along with the object code.



4. You may not copy, modify, sublicense, or distribute the Program

except as expressly provided under this License. Any attempt

otherwise to copy, modify, sublicense or distribute the Program 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.

5. 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 Program or its derivative works. These actions are

prohibited by law if you do not accept this License. Therefore, by

modifying or distributing the Program (or any work based on the

Program), you indicate your acceptance of this License to do so, and

all its terms and conditions for copying, distributing or modifying

the Program or works based on it.

6. Each time you redistribute the Program (or any work based on the

Program), the recipient automatically receives a license from the

original licensor to copy, distribute or modify the Program 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 to

this License.

7. 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 Program at all. For example, if a patent

license would not permit royalty-free redistribution of the Program 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 Program.

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.



8. If the distribution and/or use of the Program is restricted in

certain countries either by patents or by copyrighted interfaces, the

original copyright holder who places the Program 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.

9. The Free Software Foundation may publish revised and/or new versions

of the 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 Program

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 Program does not specify a version number of

this License, you may choose any version ever published by the Free Software

Foundation.

10. If you wish to incorporate parts of the Program into other free

programs whose distribution conditions are different, 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

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY

FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN

OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES

PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU. SHOULD THE

PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,

REPAIR OR CORRECTION.

12. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER

PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE

POSSIBILITY OF SUCH DAMAGES.

END OF TERMS AND CONDITIONS

The complete text of the GNU Lesser General Public License 2.1 is as follows:

GNU LESSER GENERAL PUBLIC LICENSE

Version 2.1, February 1999

Copyright (C) 1991, 1999 Free Software Foundation, Inc.

59 Temple Place, Suite 330, Boston, MA 02111-1307 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 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.

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.



GNU LESSER GENERAL PUBLIC LICENSE

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
