Jabber-Net can be used under either of two licenses.  

The Jabber Open Source License (JOSL) is probably most appropriate for
corporate use.

The GNU Public License (GPL) is probably most appropriate for
inclusion in other open source projects.

I ask that you don't use this library to build an entire commercial
Jabber/XMPP server.  There's no legal restriction against it, just
common courtesy, since my day job depends on selling servers.

This file MUST be included with any source distribution.

JOSL
------------------------------------------------------------------
Preamble

This Preamble is intended to describe, in plain English, the nature
and scope of this License. However, this Preamble is not a part of
this license. The legal effect of this License is dependent only upon
the terms of the License and not this Preamble. This License complies
with the Open Source Definition and has been approved by Open Source
Initiative. Software distributed under this License may be marked as
"OSI Certified Open Source Software."

This License provides that:

   1. You may use, sell or give away the Licensed Product, alone or as
   a component of an aggregate software distribution containing
   programs from several different sources. No royalty or other fee is
   required.

   2. Both Source Code and executable versions of the Licensed
   Product, including Modifications made by previous Contributors, are
   available for your use. (The terms "Licensed Product,"
   "Modifications," "Contributors" and "Source Code" are defined in
   the License.)

   3. You are allowed to make Modifications to the Licensed Product,
   and you can create Derivative Works from it. (The term "Derivative
   Works" is defined in the License.)

   4. By accepting the Licensed Product under the provisions of this
   License, you agree that any Modifications you make to the Licensed
   Product and then distribute are governed by the provisions of this
   License. In particular, you must make the Source Code of your
   Modifications available to others.

   5. You may use the Licensed Product for any purpose, but the
   Licensor is not providing you any warranty whatsoever, nor is the
   Licensor accepting any liability in the event that the Licensed
   Product doesn't work properly or causes you any injury or damages.

   6. If you sublicense the Licensed Product or Derivative Works, you
   may charge fees for warranty or support, or for accepting indemnity
   or liability obligations to your customers. You cannot charge for
   the Source Code.

   7. If you assert any patent claims against the Licensor relating to
   the Licensed Product, or if you breach any terms of the License,
   your rights to the Licensed Product under this License
   automatically terminate.

   You may use this License to distribute your own Derivative Works,
   in which case the provisions of this License will apply to your
   Derivative Works just as they do to the original Licensed Product.

   Alternatively, you may distribute your Derivative Works under any
   other OSI-approved Open Source license, or under a proprietary
   license of your choice. If you use any license other than this
   License, however, you must continue to fulfill the requirements of
   this License (including the provisions relating to publishing the
   Source Code) for those portions of your Derivative Works that
   consist of the Licensed Product, including the files containing
   Modifications.

   New versions of this License may be published from time to
   time. You may choose to continue to use the license terms in this
   version of the License or those from the new version. However, only
   the Licensor has the right to change the License terms as they
   apply to the Licensed Product. This License relies on precise
   definitions for certain terms. Those terms are defined when they
   are first used, and the definitions are repeated for your
   convenience in a Glossary at the end of the License.

License Terms

   1. Grant of License From Licensor. Licensor hereby grants you a
   world-wide, royalty-free, non-exclusive license, subject to third
   party intellectual property claims, to do the following:

     a. Use, reproduce, modify, display, perform, sublicense and
     distribute Licensed Product or portions thereof (including
     Modifications as hereinafter defined), in both Source Code or as
     an executable program. "Source Code" means the preferred form for
     making modifications to the Licensed Product, including all
     modules contained therein, plus any associated interface
     definition files, scripts used to control compilation and
     installation of an executable program, or a list of differential
     comparisons against the Source Code of the Licensed Product.

     b. Create Derivative Works (as that term is defined under
     U.S. copyright law) of Licensed Product by adding to or deleting
     from the substance or structure of said Licensed Product.

     c. Under claims of patents now or hereafter owned or controlled
     by Licensor, to make, use, sell, offer for sale, have made,
     and/or otherwise dispose of Licensed Product or portions thereof,
     but solely to the extent that any such claim is necessary to
     enable you to make, use, sell, offer for sale, have made, and/or
     otherwise dispose of Licensed Product or portions thereof or
     Derivative Works thereof.

   2. Grant of License to Modifications From
   Contributor. "Modifications" means any additions to or deletions
   from the substance or structure of (i) a file containing Licensed
   Product, or (ii) any new file that contains any part of Licensed
   Product. Hereinafter in this License, the term "Licensed Product"
   shall include all previous Modifications that you receive from any
   Contributor. By application of the provisions in Section 4(a)
   below, each person or entity who created or contributed to the
   creation of, and distributed, a Modification (a "Contributor")
   hereby grants you a world-wide, royalty-free, non-exclusive
   license, subject to third party intellectual property claims, to do
   the following:

     a. Use, reproduce, modify, display, perform, sublicense and
     distribute any Modifications created by such Contributor or
     portions thereof, in both Source Code or as an executable
     program, either on an unmodified basis or as part of Derivative
     Works.

     b. Under claims of patents now or hereafter owned or controlled
     by Contributor, to make, use, sell, offer for sale, have made,
     and/or otherwise dispose of Modifications or portions thereof,
     but solely to the extent that any such claim is necessary to
     enable you to make, use, sell, offer for sale, have made, and/or
     otherwise dispose of Modifications or portions thereof or
     Derivative Works thereof.

   3. Exclusions From License Grant. Nothing in this License shall be
   deemed to grant any rights to trademarks, copyrights, patents,
   trade secrets or any other intellectual property of Licensor or any
   Contributor except as expressly stated herein. No patent license is
   granted separate from the Licensed Product, for code that you
   delete from the Licensed Product, or for combinations of the
   Licensed Product with other software or hardware. No right is
   granted to the trademarks of Licensor or any Contributor even if
   such marks are included in the Licensed Product. Nothing in this
   License shall be interpreted to prohibit Licensor from licensing
   under different terms from this License any code that Licensor
   otherwise would have a right to license.

   4. Your Obligations Regarding Distribution.
      
     a. Application of This License to Your Modifications. As an
     express condition for your use of the Licensed Product, you
     hereby agree that any Modifications that you create or to which
     you contribute, and which you distribute, are governed by the
     terms of this License including, without limitation, Section
     2. Any Modifications that you create or to which you contribute
     may be distributed only under the terms of this License or a
     future version of this License released under Section 7. You must
     include a copy of this License with every copy of the
     Modifications you distribute. You agree not to offer or impose
     any terms on any Source Code or executable version of the
     Licensed Product or Modifications that alter or restrict 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 4(e).

     b. Availability of Source Code. You must make available, under
     the terms of this License, the Source Code of the Licensed
     Product and any Modifications that you distribute, either on the
     same media as you distribute any executable or other form of the
     Licensed Product, or via a mechanism generally accepted in the
     software development community for the electronic transfer of
     data (an "Electronic Distribution Mechanism"). The Source Code
     for any version of Licensed Product or Modifications that you
     distribute 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 said Licensed Product or
     Modifications has been made available. You are responsible for
     ensuring that the Source Code version remains available even if
     the Electronic Distribution Mechanism is maintained by a third
     party.

     c. Description of Modifications. You must cause any Modifications
     that you create or to which you contribute, and which you
     distribute, to contain a file documenting the additions, changes
     or deletions you made to create or contribute to those
     Modifications, and the dates of any such additions, changes or
     deletions. You must include a prominent statement that the
     Modifications are derived, directly or indirectly, from the
     Licensed Product and include the names of the Licensor and any
     Contributor to the Licensed Product in (i) the Source Code and
     (ii) in any notice displayed by a version of the Licensed Product
     you distribute or in related documentation in which you describe
     the origin or ownership of the Licensed Product. You may not
     modify or delete any preexisting copyright notices in the
     Licensed Product.


     d. Intellectual Property Matters.

       i. Third Party Claims. If you have knowledge that a license to
       a third party's intellectual property right is required to
       exercise the rights granted by this License, you must include a
       text file with the Source Code distribution titled "LEGAL" that
       describes the claim and the party making the claim in
       sufficient detail that a recipient will know whom to
       contact. If you obtain such knowledge after you make any
       Modifications available as described in Section 4(b), you shall
       promptly modify the LEGAL file in all copies you make available
       thereafter and shall take other steps (such as notifying
       appropriate mailing lists or newsgroups) reasonably calculated
       to inform those who received the Licensed Product from you that
       new knowledge has been obtained.

       ii. Contributor APIs. If your Modifications include an
       application programming interface ("API") and you have
       knowledge of patent licenses that are reasonably necessary to
       implement that API, you must also include this information in
       the LEGAL file.

       iii. Representations. You represent that, except as disclosed
       pursuant to 4(d)(i) above, you believe that any Modifications
       you distribute are your original creations and that you have
       sufficient rights to grant the rights conveyed by this License.

     e. Required Notices. You must duplicate this License in any
     documentation you provide along with the Source Code of any
     Modifications you create or to which you contribute, and which
     you distribute, wherever you describe recipients' rights relating
     to Licensed Product. You must duplicate the notice contained in
     Exhibit A (the "Notice") in each file of the Source Code of any
     copy you distribute of the Licensed Product. If you created a
     Modification, you may add your name as a Contributor to the
     Notice. If it is not possible to put the 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 file) where a
     user would be likely to look for such a notice. You may choose to
     offer, and charge a fee for, warranty, support, indemnity or
     liability obligations to one or more recipients of Licensed
     Product. However, you may do so only on your own behalf, and not
     on behalf of the Licensor or any Contributor. You must make it
     clear that any such warranty, support, indemnity or liability
     obligation is offered by you alone, and you hereby agree to
     indemnify the Licensor and every Contributor for any liability
     incurred by the Licensor or such Contributor as a result of
     warranty, support, indemnity or liability terms you offer.

     f. Distribution of Executable Versions. You may distribute
     Licensed Product as an executable program under a license of your
     choice that may contain terms different from this License
     provided (i) you have satisfied the requirements of Sections 4(a)
     through 4(e) for that distribution, (ii) you include a
     conspicuous notice in the executable version, related
     documentation and collateral materials stating that the Source
     Code version of the Licensed Product is available under the terms
     of this License, including a description of how and where you
     have fulfilled the obligations of Section 4(b), (iii) you retain
     all existing copyright notices in the Licensed Product, and (iv)
     you make it clear that any terms that differ from this License
     are offered by you alone, not by Licensor or any Contributor. You
     hereby agree to indemnify the Licensor and every Contributor for
     any liability incurred by Licensor or such Contributor as a
     result of any terms you offer.

     g. Distribution of Derivative Works. You may create Derivative
     Works (e.g., combinations of some or all of the Licensed Product
     with other code) and distribute the Derivative Works as products
     under any other license you select, with the proviso that the
     requirements of this License are fulfilled for those portions of
     the Derivative Works that consist of the Licensed Product or any
     Modifications thereto.

   5. 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 Licensed Product due to statute,
   judicial order, or regulation, then you must (i) comply with the
   terms of this License to the maximum extent possible, (ii) cite the
   statute or regulation that prohibits you from adhering to the
   License, and (iii) describe the limitations and the code they
   affect. Such description must be included in the LEGAL file
   described in Section 4(d), 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 at computer programming
   to be able to understand it.

   6. Application of This License. This License applies to code to
   which Licensor or Contributor has attached the Notice in Exhibit A,
   which is incorporated herein by this reference.

   7. Versions of This License.

     a. New Versions. Licensor may publish from time to time revised
     and/or new versions of the License.

     b. Effect of New Versions. Once Licensed Product 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 Licensed Product under the terms of
     any subsequent version of the License published by Licensor. No
     one other than Lic ensor has the right to modify the terms
     applicable to Licensed Product created under this License.

     c. Derivative Works of this License. If you create or use a
     modified version of this License, which you may do only in order
     to apply it to software that is not already a Licensed Product
     under this License, you must rename your license so that it is
     not confusingly similar to this License, and must make it clear
     that your license contains terms that differ from this
     License. In so naming your license, you may not use any trademark
     of Licensor or any Contributor.

   8. Disclaimer of Warranty. LICENSED PRODUCT IS PROVIDED UNDER THIS
   LICENSE ON AN "AS IS" BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER
   EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT
   THE LICENSED PRODUCT IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A
   PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE
   QUALITY AND PERFORMANCE OF THE LICENSED PRODUCT IS WITH YOU. SHOULD
   LICENSED PRODUCT PROVE DEFECTIVE IN ANY RESPECT, YOU (AND NOT THE
   LICENSOR 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 LICENSED
   PRODUCT IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.

   9. Termination.

     a. Automatic Termination Upon Breach. This license and the rights
     granted hereunder will terminate automatically if you fail to
     comply with the terms herein and fail to cure such breach within
     thirty (30) days of becoming aware of the breach. All sublicenses
     to the Licensed Product that are properly granted shall survive
     any termination of this license. Provisions that, by their
     nature, must remain in effect beyond the termination of this
     License, shall survive.

     b. Termination Upon Assertion of Patent Infringement. If you
     initiate litigation by asserting a patent infringement claim
     (excluding declaratory judgment actions) against Licensor or a
     Contributor (Licensor or Contributor against whom you file such
     an action is referred to herein as "Respondent") alleging that
     Licensed Product directly or indirectly infringes any patent,
     then any and all rights granted by such Respondent to you under
     Sections 1 or 2 of this License shall terminate prospectively
     upon sixty (60) days notice from Respondent (the "Notice Period")
     unless within that Notice Period you either agree in writing (i)
     to pay Respondent a mutually agreeable reasonably royalty for
     your past or future use of Licensed Product made by such
     Respondent, or (ii) withdraw your litigation claim with respect
     to Licensed Product against such Respondent. If within said
     Notice Period 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 Licensor
     to you under Sections 1 and 2 automatically terminate at the
     expiration of said Notice Period.

     c. Reasonable Value of This License. If you assert a patent
     infringement claim against Respondent alleging that Licensed
     Product 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 said Respondent under Sections 1
     and 2 shall be taken into account in determining the amount or
     value of any payment or license.

     d. No Retroactive Effect of Termination. In the event of
     termination under Sections 9(a) or 9(b) above, all end user
     license agreements (excluding licenses to distributors and
     reselle rs) that have been validly granted by you or any
     distributor hereunder prior to termination shall survive
     termination.

  10. Limitation of Liability. UNDER NO CIRCUMSTANCES AND UNDER NO
  LEGAL THEORY, WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR
  OTHERWISE, SHALL THE LICENSOR, ANY CONTRIBUTOR, OR ANY DISTRIBUTOR
  OF LICENSED PRODUCT, 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
  PARTYÕS 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.

  11. Responsibility for Claims. As between Licensor and Contributors,
  each party is responsible for claims and damages arising, directly
  or indirectly, out of its utilization of rights under this
  License. You agree to work with Licensor and Contributors to
  distribute such responsibility on an equitable basis. Nothing herein
  is intended or shall be deemed to constitute any admission of
  liability.

  12. U.S. Government End Users. The Licensed Product 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 Licensed Product with only those
  rights set forth herein.


  13. Miscellaneous. This License represents the complete agreement
  concerning the 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. You expressly agree that any
  litigation relating to this license shall be subject to the
  jurisdiction of the Federal Courts of the Northern District of
  California or the Superior Court of the County of Santa Clara,
  California (as appropriate), 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. You and Licensor expressly waive any rights to a jury
  trial in any litigation concerning Licensed Product or this
  License. Any law or regulation that provides that the language of a
  contract shall be construed against the drafter shall not apply to
  this License.

  14. Definition of "You" in This License. "You" throughout this
  License, whether in upper or lower case, means an individual or a
  legal entity exercising rights under, and complying with all of the
  terms of, this License or a future version of this License issued
  under Section 7. For legal entities, "you" includes any entity that
  controls, is controlled by, or is under common control with you. For
  purposes of this definition, "control" means (i) the power, direct
  or indirect, to cause the direction or management of such entity,
  whether by contract or otherwise, or (ii) ownership of fifty percent
  (50%) or more of the outstanding shares, or (iii) beneficial
  ownership of such entity.

  15. Glossary. All defined terms in this License that are used in
  more than one Section of this License are repeated here, in
  alphabetical order, for the convenience of the reader. The Section
  of this License in which each defined term is first used is shown in
  parentheses. Contributor: Each person or entity who created or
  contributed to the creation of, and distributed, a
  Modification. (See Section 2)

  Derivative Works: That term as used in this License is defined under
  U.S. copyright law. (See Section 1(b))

  License: This Jabber Open Source License. (See first paragraph of
  License)

  Licensed Product: Any Jabber Product licensed pursuant to this
  License. The term "Licensed Product" includes all previous
  Modifications from any Contributor that you receive. (See first
  paragraph of License and Section 2)

  Licensor: Jabber.Com, Inc. (See first paragraph of License)

  Modifications: Any additions to or deletions from the substance or
  structure of (i) a file containing Licensed Product, or (ii) any new
  file that contains any part of Licensed Product. (See Section 2)

  Notice: The notice contained in Exhibit A. (See Section 4(e))

  Source Code: The preferred form for making modifications to the
  Licensed Product, including all modules contained therein, plus any
  associated interface definition files, scripts used to control
  compilation and installation of an executable program, or a list of
  differential comparisons against the Source Code of the Licensed
  Product. (See Section 1(a))

		    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.

    <one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

    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.

  <signature of Ty Coon>, 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.
