     non-exclusive license, subject to third party intellectual property

     claims:

          (a)  under intellectual property rights (other than patent or

          trademark) Licensable by Initial Developer to use, reproduce,

          modify, display, perform, sublicense and distribute the Original

          Code (or portions thereof) with or without Modifications, and/or

          as part of a Larger Work; and

          (b) under Patents Claims infringed by the making, using or

          selling of Original Code, to make, have made, use, practice,

          sell, and offer for sale, and/or otherwise dispose of the

          Original Code (or portions thereof).

          (c) the licenses granted in this Section 2.1(a) and (b) are

          effective on the date Initial Developer first distributes

          Original Code under the terms of this License.

          (d) Notwithstanding Section 2.1(b) above, no patent license is

          granted: 1) for code that You delete from the Original Code; 2)

          separate from the Original Code;  or 3) for infringements caused

          by: i) the modification of the Original Code or ii) the

          combination of the Original Code with other software or devices.

          unmodified basis, with other Modifications, as Covered Code

          and/or as part of a Larger Work; and

          (b) under Patent Claims infringed by the making, using, or

          selling of  Modifications made by that Contributor either alone

          and/or in combination with its Contributor Version (or portions

          of such combination), to make, use, sell, offer for sale, have

          made, and/or otherwise dispose of: 1) Modifications made by that

          Contributor (or portions thereof); and 2) the combination of

          Modifications made by that Contributor with its Contributor

          Version (or portions of such combination).

          (c) the licenses granted in Sections 2.2(a) and 2.2(b) are

          effective on the date Contributor first makes Commercial Use of

          the Covered Code.

          (d)    Notwithstanding Section 2.2(b) above, no patent license is

          granted: 1) for any code that Contributor has deleted from the

          Contributor Version; 2)  separate from the Contributor Version;

          3)  for infringements caused by: i) third party modifications of

          Contributor Version or ii)  the combination of Modifications made

          by that Contributor with other software  (except as part of the

          Contributor Version) or other devices; or 4) under Patent Claims

          infringed by Covered Code in the absence of Modifications made by

          that Contributor.

3. Distribution Obligations.

     3.1. Application of License.

     The Modifications which You create or to which You contribute are

     governed by the terms of this License, including without limitation

     Section 2.2. The Source Code version of Covered Code may be

     distributed only under the terms of this License or a future version

     of this License released under Section 6.1, and You must include a

     copy of this License with every copy of the Source Code You

     distribute. You may not offer or impose any terms on any Source Code

     version that alters or restricts the applicable version of this

     License or the recipients' rights hereunder. However, You may include

     an additional document offering the additional rights described in

     Section 3.5.

     3.2. Availability of Source Code.

     Any Modification which You create or to which You contribute must be

     made available in Source Code form under the terms of this License

     either on the same media as an Executable version or via an accepted

     Electronic Distribution Mechanism to anyone to whom you made an

     Executable version available; and if made available via Electronic

     Distribution Mechanism, must remain available for at least twelve (12)

     months after the date it initially became available, or at least six

     (6) months after a subsequent version of that particular Modification

     has been made available to such recipients. You are responsible for

     ensuring that the Source Code version remains available even if the

     Electronic Distribution Mechanism is maintained by a third party.

     3.3. Description of Modifications.

     You must cause all Covered Code to which You contribute to contain a

     file documenting the changes You made to create that Covered Code and

     the date of any change. You must include a prominent statement that

     the Modification is derived, directly or indirectly, from Original

     Code provided by the Initial Developer and including the name of the

     Initial Developer in (a) the Source Code, and (b) in any notice in an

     Executable version or related documentation in which You describe the

     origin or ownership of the Covered Code.

     3.4. Intellectual Property Matters

          (a) Third Party Claims.

          If Contributor has knowledge that a license under a third party's

          intellectual property rights is required to exercise the rights

          granted by such Contributor under Sections 2.1 or 2.2,

          Contributor must include a text file with the Source Code

          distribution titled "LEGAL" which describes the claim and the

          party making the claim in sufficient detail that a recipient will

          know whom to contact. If Contributor obtains such knowledge after

          the Modification is made available as described in Section 3.2,

          Contributor shall promptly modify the LEGAL file in all copies

          Contributor makes available thereafter and shall take other steps

          (such as notifying appropriate mailing lists or newsgroups)

          reasonably calculated to inform those who received the Covered

          Code that new knowledge has been obtained.

          (b) Contributor APIs.

          If Contributor's Modifications include an application programming

          interface and Contributor has knowledge of patent licenses which

          are reasonably necessary to implement that API, Contributor must

          also include this information in the LEGAL file.

               (c)    Representations.

          Contributor represents that, except as disclosed pursuant to

          Section 3.4(a) above, Contributor believes that Contributor's

          Modifications are Contributor's original creation(s) and/or

          Contributor has sufficient rights to grant the rights conveyed by

          this License.

     3.5. Required Notices.

     You must duplicate the notice in Exhibit A in each file of the Source

     Code.  If it is not possible to put such notice in a particular Source

     Code file due to its structure, then You must include such notice in a

     location (such as a relevant directory) where a user would be likely

     to look for such a notice.  If You created one or more Modification(s)

     You may add your name as a Contributor to the notice described in

     Exhibit A.  You must also duplicate this License in any documentation

     for the Source Code where You describe recipients' rights or ownership

     rights relating to Covered Code.  You may choose to offer, and to

     charge a fee for, warranty, support, indemnity or liability

     obligations to one or more recipients of Covered Code. However, You

     may do so only on Your own behalf, and not on behalf of the Initial

     Developer or any Contributor. You must make it absolutely clear than

     any such warranty, support, indemnity or liability obligation is

     offered by You alone, and You hereby agree to indemnify the Initial

     Developer and every Contributor for any liability incurred by the

     Initial Developer or such Contributor as a result of warranty,

     support, indemnity or liability terms You offer.

     3.6. Distribution of Executable Versions.

     You may distribute Covered Code in Executable form only if the

     requirements of Section 3.1-3.5 have been met for that Covered Code,

     and if You include a notice stating that the Source Code version of

     the Covered Code is available under the terms of this License,

     including a description of how and where You have fulfilled the

     obligations of Section 3.2. The notice must be conspicuously included

     in any notice in an Executable version, related documentation or

     collateral in which You describe recipients' rights relating to the

     Covered Code. You may distribute the Executable version of Covered

     Code or ownership rights under a license of Your choice, which may

     contain terms different from this License, provided that You are in

     compliance with the terms of this License and that the license for the

     Executable version does not attempt to limit or alter the recipient's

     rights in the Source Code version from the rights set forth in this

     License. If You distribute the Executable version under a different

     license You must make it absolutely clear that any terms which differ

     from this License are offered by You alone, not by the Initial

     Developer or any Contributor. You hereby agree to indemnify the

     Initial Developer and every Contributor for any liability incurred by

     the Initial Developer or such Contributor as a result of any such

     terms You offer.

     3.7. Larger Works.

     You may create a Larger Work by combining Covered Code with other code

     not governed by the terms of this License and distribute the Larger

     Work as a single product. In such a case, You must make sure the

     requirements of this License are fulfilled for the Covered Code.

4. Inability to Comply Due to Statute or Regulation.

     If it is impossible for You to comply with any of the terms of this

     License with respect to some or all of the Covered Code due to

     statute, judicial order, or regulation then You must: (a) comply with

     the terms of this License to the maximum extent possible; and (b)

     describe the limitations and the code they affect. Such description

     must be included in the LEGAL file described in Section 3.4 and must

     be included with all distributions of the Source Code. Except to the

     extent prohibited by statute or regulation, such description must be

     sufficiently detailed for a recipient of ordinary skill to be able to

     understand it.

5. Application of this License.

     This License applies to code to which the Initial Developer has

     attached the notice in Exhibit A and to related Covered Code.

6. Versions of the License.

     6.1. New Versions.

     Netscape Communications Corporation ("Netscape") may publish revised

     and/or new versions of the License from time to time. Each version

     will be given a distinguishing version number.

     6.2. Effect of New Versions.

     Once Covered Code has been published under a particular version of the

     License, You may always continue to use it under the terms of that

     version. You may also choose to use such Covered Code under the terms

     of any subsequent version of the License published by Netscape. No one

     other than Netscape has the right to modify the terms applicable to

     Covered Code created under this License.

     6.3. Derivative Works.

     If You create or use a modified version of this License (which you may

     only do in order to apply it to code which is not already Covered Code

     governed by this License), You must (a) rename Your license so that

     the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",

     "MPL", "NPL" or any confusingly similar phrase do not appear in your

     license (except to note that your license differs from this License)

     and (b) otherwise make it clear that Your version of the license

     contains terms which differ from the Mozilla Public License and

     Netscape Public License. (Filling in the name of the Initial

     Developer, Original Code or Contributor in the notice described in

     Exhibit A shall not of themselves be deemed to be modifications of

     this License.)

7. DISCLAIMER OF WARRANTY.

     COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,

     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,

     WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF

     DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.

     THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE

     IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,

     YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE

     COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER

     OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF

     ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.

8. TERMINATION.

     8.1.  This License and the rights granted hereunder will terminate

     automatically if You fail to comply with terms herein and fail to cure

     such breach within 30 days of becoming aware of the breach. All

     sublicenses to the Covered Code which are properly granted shall

     survive any termination of this License. Provisions which, by their

     nature, must remain in effect beyond the termination of this License

     shall survive.

     8.2.  If You initiate litigation by asserting a patent infringement

     claim (excluding declatory judgment actions) against Initial Developer

     or a Contributor (the Initial Developer or Contributor against whom

     You file such action is referred to as "Participant")  alleging that:

     (a)  such Participant's Contributor Version directly or indirectly

     infringes any patent, then any and all rights granted by such

     Participant to You under Sections 2.1 and/or 2.2 of this License

     shall, upon 60 days notice from Participant terminate prospectively,

     unless if within 60 days after receipt of notice You either: (i)

     agree in writing to pay Participant a mutually agreeable reasonable

     royalty for Your past and future use of Modifications made by such

     Participant, or (ii) withdraw Your litigation claim with respect to

     the Contributor Version against such Participant.  If within 60 days

     of notice, a reasonable royalty and payment arrangement are not

     mutually agreed upon in writing by the parties or the litigation claim

     is not withdrawn, the rights granted by Participant to You under

     Sections 2.1 and/or 2.2 automatically terminate at the expiration of

     the 60 day notice period specified above.

     (b)  any software, hardware, or device, other than such Participant's

     Contributor Version, directly or indirectly infringes any patent, then

     any rights granted to You by such Participant under Sections 2.1(b)

     and 2.2(b) are revoked effective as of the date You first made, used,

     sold, distributed, or had made, Modifications made by that

     Participant.

     8.3.  If You assert a patent infringement claim against Participant

     alleging that such Participant's Contributor Version directly or

     indirectly infringes any patent where such claim is resolved (such as

     by license or settlement) prior to the initiation of patent

     infringement litigation, then the reasonable value of the licenses

     granted by such Participant under Sections 2.1 or 2.2 shall be taken

     into account in determining the amount or value of any payment or

     license.

     8.4.  In the event of termination under Sections 8.1 or 8.2 above,

     all end user license agreements (excluding distributors and resellers)

     which have been validly granted by You or any distributor hereunder

     prior to termination shall survive termination.

9. LIMITATION OF LIABILITY.

     UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT

     (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL

     DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,

     OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR

     ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY

     CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,

     WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER

     COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN

     INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF

     LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY

     RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW

     PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE

     EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO

     THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.

10. U.S. GOVERNMENT END USERS.

     The Covered Code is a "commercial item," as that term is defined in

     48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer

     software" and "commercial computer software documentation," as such

     terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48

     C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995),

     all U.S. Government End Users acquire Covered Code with only those

     rights set forth herein.

11. MISCELLANEOUS.

     This License represents the complete agreement concerning subject

     matter hereof. If any provision of this License is held to be

     unenforceable, such provision shall be reformed only to the extent

     necessary to make it enforceable. This License shall be governed by

     California law provisions (except to the extent applicable law, if

     any, provides otherwise), excluding its conflict-of-law provisions.

     With respect to disputes in which at least one party is a citizen of,

     or an entity chartered or registered to do business in the United

     States of America, any litigation relating to this License shall be

     subject to the jurisdiction of the Federal Courts of the Northern

     District of California, with venue lying in Santa Clara County,

     California, with the losing party responsible for costs, including

     without limitation, court costs and reasonable attorneys' fees and

     expenses. The application of the United Nations Convention on

     Contracts for the International Sale of Goods is expressly excluded.

     Any law or regulation which provides that the language of a contract

     shall be construed against the drafter shall not apply to this

     License.

12. RESPONSIBILITY FOR CLAIMS.

     As between Initial Developer and the Contributors, each party is

     responsible for claims and damages arising, directly or indirectly,

     out of its utilization of rights under this License and You agree to

     work with Initial Developer and Contributors to distribute such

     responsibility on an equitable basis. Nothing herein is intended or

     shall be deemed to constitute any admission of liability.

13. MULTIPLE-LICENSED CODE.

     Initial Developer may designate portions of the Covered Code as

     "Multiple-Licensed".  "Multiple-Licensed" means that the Initial

     Developer permits you to utilize portions of the Covered Code under

     Your choice of the NPL or the alternative licenses, if any, specified

     by the Initial Developer in the file described in Exhibit A.

ANNEX A: The GNU GENERAL PUBLIC LICENSE

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

                    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

            How to Apply These Terms to Your New Programs

  If you develop a new program, and you want it to be of the greatest

possible use to the public, the best way to achieve this is to make it

free software which everyone can redistribute and change under these terms.

  To do so, attach the following notices to the program.  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.

    Copyright (C)   

    This program is free software; you can redistribute it and/or modify

    it under the terms of the GNU General Public License as published by

    the Free Software Foundation; either version 2 of the License, or

    (at your option) any later version.

    This program is distributed in the hope that it will be useful,

    but WITHOUT ANY WARRANTY; without even the implied warranty of

    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the

    GNU General Public License for more details.

    You should have received a copy of the GNU General Public License

    along with this program; if not, write to the Free Software

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

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this

when it starts in an interactive mode:

    Gnomovision version 69, Copyright (C) year name of author

    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

    This is free software, and you are welcome to redistribute it

    under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate

parts of the General Public License.  Of course, the commands you use may

be called something other than `show w' and `show c'; they could even be

mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your

school, if any, to sign a "copyright disclaimer" for the program, if

necessary.  Here is a sample; alter the names:

  Yoyodyne, Inc., hereby disclaims all copyright interest in the program

  `Gnomovision' (which makes passes at compilers) written by James Hacker.

  , 1 April 1989

  Ty Coon, President of Vice

This General Public License does not permit incorporating your program into

proprietary programs.  If your program is a subroutine library, you may

consider it more useful to permit linking proprietary applications with the

library.  If this is what you want to do, use the GNU Library General

Public License instead of this License.

ANNEX B : THE GNU LESSER GENERAL PUBLIC LICENSE

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

                  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
