    <title>Terms and Conditions for Copying, Distribution and Modification</title>

    <para>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''.</para>

    <para>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.</para>

    <para>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.</para>

    <para>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.</para>

    <para>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:</para>

    <para>a) You must cause the modified files to carry prominent

    notices stating that you changed the files and the date of any

    change.</para>

    <para>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.</para>

    <para>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.)</para>

    <para>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.</para>

    <para>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.</para>

    <para>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.</para>

    <para>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:</para>

    <para>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,</para>

    <para>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,</para>

    <para>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.)</para>

    <para>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.</para>

    <para>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.</para>

    <para>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.</para>

    <para>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.</para>

    <para>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.</para>

    <para>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.</para>

    <para>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.</para>

    <para>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.</para>

    <para>This section is intended to make thoroughly clear what is

    believed to be a consequence of the rest of this License.</para>

    <para>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.</para>

    <para>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.</para>

    <para>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.</para>

    <para>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.</para>

    <para><emphasis>NO WARRANTY</emphasis></para>

    <para>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.</para>

    <para>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.</para>

    <para><emphasis>End of Terms and Conditions.</emphasis></para>
