The Star Traders game is free software that is distributed under the terms
of the GNU  General Public License.  The actual  copyright on this program
("the Program", in the language  of the License) belongs to John Zaitseff,
although  the text  of the  License itself  belongs to  the  Free Software
Foundation.

Even though  the GNU  General Public License does NOT require  you to send
your modifications back to the author,  it is considered "good form" to do
so,  as this  allows your  modifications  to be  incorporated into  future
versions of the program, allowing others to benefit from them.

			GNU GENERAL PUBLIC LICENSE
			 Version 3, 29 June 2007

   Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>

       Everyone is permitted to copy and distribute verbatim copies
	of this license document, but changing it is not allowed.

				 Preamble

The GNU  General Public License is  a free, copyleft  license for software
and other kinds of works.

The licenses for  most software and other practical  works are designed to
take away  your freedom to share  and change the works.   By contrast, the
GNU General Public License is  intended to guarantee your freedom to share
and  change all  versions  of a  program---to  make sure  it remains  free
software for all its users.  We, the Free Software Foundation, use the GNU
General Public  License for most of  our software; it applies  also to any
other work  released this way  by its authors.   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 them 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 prevent others  from denying you these
rights or asking you to surrender the rights.  Therefore, you have certain
responsibilities  if you  distribute copies  of  the software,  or if  you
modify it: responsibilities to respect the freedom of others.

For example, if you distribute copies of such a program, whether gratis or
for a fee, you  must pass on to the recipients the  same freedoms that you
received.   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.

Developers that  use the GNU GPL  protect your rights with  two steps: (1)
assert copyright  on the software, and  (2) offer you  this License giving
you legal permission to copy, distribute and/or modify it.

For the developers' and authors' protection, the GPL clearly explains that
there is no warranty for this free software.  For both users' and authors'
sake, the  GPL requires  that modified versions  be marked as  changed, so
that  their problems  will not  be  attributed erroneously  to authors  of
previous versions.

Some devices are designed to deny  users access to install or run modified
versions of the software inside them, although the manufacturer can do so.
This  is fundamentally  incompatible  with the  aim  of protecting  users'
freedom  to change  the software.   The systematic  pattern of  such abuse
occurs in the area of products  for individuals to use, which is precisely
where it is  most unacceptable.  Therefore, we have  designed this version
of the GPL to prohibit the  practice for those products.  If such problems
arise  substantially in  other  domains,  we stand  ready  to extend  this
provision to  those domains in  future versions of  the GPL, as  needed to
protect the freedom of users.

Finally,  every  program is  threatened  constantly  by software  patents.
States  should  not allow  patents  to  restrict  development and  use  of
software on  general-purpose computers, but in  those that do,  we wish to
avoid the special danger that patents applied to a free program could make
it effectively proprietary.  To prevent this, the GPL assures that patents
cannot be used to render the program non-free.

The   precise  terms   and  conditions   for  copying,   distribution  and
modification follow.

			   TERMS AND CONDITIONS

   0. Definitions.

"This License" refers to version 3 of the GNU General Public License.

"Copyright" also  means copyright-like laws  that apply to other  kinds of
works, such as semiconductor masks.

"The  Program"  refers  to  any  copyrightable work  licensed  under  this
License.   Each   licensee  is   addressed  as  "you".    "Licensees"  and
"recipients" may be individuals or organizations.

To "modify" a work means to copy from  or adapt all or part of the work in
a  fashion requiring  copyright permission,  other than  the making  of an
exact  copy.  The resulting  work is  called a  "modified version"  of the
earlier work or a work "based on" the earlier work.

A "covered  work" means either the  unmodified Program or a  work based on
the Program.

To  "propagate"  a  work  means  to  do anything  with  it  that,  without
permission, would make you directly or secondarily liable for infringement
under  applicable copyright  law, except  executing  it on  a computer  or
modifying  a  private copy.   Propagation  includes copying,  distribution
(with or  without modification),  making available to  the public,  and in
some countries other activities as well.

To  "convey" a  work  means any  kind  of propagation  that enables  other
parties to make or receive copies.  Mere interaction with a user through a
computer network, with no transfer of a copy, is not conveying.

An interactive user interface  displays "Appropriate Legal Notices" to the
extent that it includes a  convenient and prominently visible feature that
(1) displays an appropriate copyright notice,  and (2) tells the user that
there is  no warranty for the  work (except to the  extent that warranties
are provided), that licensees may  convey the work under this License, and
how to view a  copy of this License.  If the interface  presents a list of
user commands  or options, such  as a menu,  a prominent item in  the list
meets this criterion.

   1. Source Code.

The "source  code" for  a work means  the preferred  form of the  work for
making modifications to it.  "Object  code" means any non-source form of a
work.

A  "Standard Interface"  means an  interface  that either  is an  official
standard  defined by  a  recognized standards  body,  or, in  the case  of
interfaces specified  for a particular  programming language, one  that is
widely used among developers working in that language.

The "System Libraries" of an  executable work include anything, other than
the work as a whole, that (a)  is included in the normal form of packaging
a Major Component, but which is  not part of that Major Component, and (b)
serves only  to enable use  of the work  with that Major Component,  or to
implement a Standard Interface for which an implementation is available to
the public  in source  code form.  A  "Major Component", in  this context,
means a  major essential component (kernel,  window system, and  so on) of
the specific operating system (if  any) on which the executable work runs,
or a compiler used to produce the work, or an object code interpreter used
to run it.

The "Corresponding  Source" for a work  in object code form  means all the
source code needed to generate,  install, and (for an executable work) run
the object code and to modify the work, including scripts to control those
activities.  However, it does not  include the work's System Libraries, or
general-purpose tools or generally  available free programs which are used
unmodified in  performing those activities but  which are not  part of the
work.   For example,  Corresponding Source  includes  interface definition
files associated with  source files for the work, and  the source code for
shared  libraries and  dynamically  linked subprograms  that  the work  is
specifically designed  to require, such as by  intimate data communication
or control flow between those subprograms and other parts of the work.

The  Corresponding  Source  need  not  include  anything  that  users  can
regenerate automatically from other parts of the Corresponding Source.

The Corresponding Source for a work in source code form is that same work.

   2. Basic Permissions.

All  rights  granted  under this  License  are  granted  for the  term  of
copyright  on  the  Program,  and  are  irrevocable  provided  the  stated
conditions  are  met.   This  License explicitly  affirms  your  unlimited
permission  to run  the unmodified  Program.   The output  from running  a
covered work  is covered  by this  License only if  the output,  given its
content,  constitutes  a covered  work.   This  License acknowledges  your
rights of fair use or other equivalent, as provided by copyright law.

You may  make, run  and propagate  covered works that  you do  not convey,
without conditions  so long  as your license  otherwise remains  in force.
You may convey covered works to others for the sole purpose of having them
make modifications exclusively for you, or provide you with facilities for
running  those works,  provided that  you comply  with the  terms  of this
License in conveying all material  for which you do not control copyright.
Those  thus  making or  running  the  covered works  for  you  must do  so
exclusively on  your behalf,  under your direction  and control,  on terms
that prohibit  them from  making any copies  of your  copyrighted material
outside their relationship with you.

Conveying  under any  other circumstances  is permitted  solely  under the
conditions stated below.  Sublicensing is not allowed; section 10 makes it
unnecessary.

   3. Protecting Users' Legal Rights From Anti-Circumvention Law.

No covered work shall be deemed part of an effective technological measure
under any  applicable law fulfilling  obligations under article 11  of the
WIPO  copyright  treaty adopted  on  20  December  1996, or  similar  laws
prohibiting or restricting circumvention of such measures.

When  you convey  a covered  work,  you waive  any legal  power to  forbid
circumvention of  technological measures to the  extent such circumvention
is effected  by exercising rights under  this License with  respect to the
covered  work,  and you  disclaim  any  intention  to limit  operation  or
modification  of the  work as  a means  of enforcing,  against  the work's
users,  your or  third parties'  legal rights  to forbid  circumvention of
technological measures.

   4. Conveying Verbatim Copies.

You may convey 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; keep  intact all
notices stating  that this License  and any non-permissive terms  added in
accord with  section 7 apply to the  code; keep intact all  notices of the
absence of  any warranty; and give  all recipients a copy  of this License
along with the Program.

You may charge  any price or no  price for each copy that  you convey, and
you may offer support or warranty protection for a fee.

   5. Conveying Modified Source Versions.

You  may convey  a work  based  on the  Program, or  the modifications  to
produce it from the Program, in the form of source code under the terms of
section 4, provided that you also meet all of these conditions:

a) The work must carry prominent notices stating that you modified it, and
   giving a relevant date.

b) The work must carry prominent notices stating that it is released under
   this  License   and  any  conditions  added  under   section  7.   This
   requirement modifies the  requirement in section 4 to  "keep intact all
   notices".

c) You  must license the  entire work, as  a whole, under this  License to
   anyone  who  comes  into  possession  of a  copy.   This  License  will
   therefore apply, along with  any applicable section 7 additional terms,
   to the whole of the work, and all its parts, regardless of how they are
   packaged.  This License gives no  permission to license the work in any
   other  way, but  it does  not invalidate  such permission  if  you have
   separately received it.

d) If  the  work  has  interactive  user  interfaces,  each  must  display
   Appropriate  Legal Notices;  however,  if the  Program has  interactive
   interfaces  that do not  display Appropriate  Legal Notices,  your work
   need not make them do so.

A compilation of a covered work with other separate and independent works,
which are  not by their nature  extensions of the covered  work, and which
are not  combined with it  such as to  form a larger  program, in or  on a
volume of  a storage or distribution  medium, is called  an "aggregate" if
the  compilation and its  resulting copyright  are not  used to  limit the
access  or  legal  rights  of  the compilation's  users  beyond  what  the
individual works permit.  Inclusion of a covered work in an aggregate does
not cause this License to apply to the other parts of the aggregate.

   6. Conveying Non-Source Forms.

You  may convey a  covered work  in object  code form  under the  terms of
sections  4 and  5, provided  that  you also  convey the  machine-readable
Corresponding  Source under the  terms of  this License,  in one  of these
ways:

a) Convey  the  object  code  in,  or  embodied  in,  a  physical  product
   (including  a   physical  distribution  medium),   accompanied  by  the
   Corresponding  Source fixed  on a  durable physical  medium customarily
   used for software interchange.

b) Convey  the  object  code  in,  or  embodied  in,  a  physical  product
   (including a  physical distribution  medium), accompanied by  a written
   offer, valid  for at  least three years  and valid  for as long  as you
   offer spare parts  or customer support for that  product model, to give
   anyone  who  possesses  the  object  code  either (1)  a  copy  of  the
   Corresponding  Source for  all  the  software in  the  product that  is
   covered by this License, on  a durable physical medium customarily used
   for software interchange, for a price no more than your reasonable cost
   of physically  performing this  conveying of source,  or (2)  access to
   copy the Corresponding Source from a network server at no charge.

c) Convey individual copies of the  object code with a copy of the written
   offer to provide the Corresponding Source.  This alternative is allowed
   only  occasionally and noncommercially,  and only  if you  received the
   object code with such an offer, in accord with subsection 6b.

d) Convey the  object code  by offering  access from  a  designated  place
   (gratis  or  for  a  charge),   and  offer  equivalent  access  to  the
   Corresponding  Source in  the same  way through  the same  place  at no
   further  charge.    You  need  not  require  recipients   to  copy  the
   Corresponding Source along with the  object code.  If the place to copy
   the object code is a network server, the Corresponding Source may be on
   a different  server (operated  by you or  a third party)  that supports
   equivalent copying  facilities, provided you  maintain clear directions
   next to the object code  saying where to find the Corresponding Source.
   Regardless of  what server hosts  the Corresponding Source,  you remain
   obligated  to ensure  that it  is available  for as  long as  needed to
   satisfy these requirements.

e) Convey  the object code  using peer-to-peer transmission,  provided you
   inform other  peers where the  object code and Corresponding  Source of
   the work  are being offered  to the general  public at no  charge under
   subsection 6d.

A separable portion of the object code, whose source code is excluded from
the  Corresponding Source as  a System  Library, need  not be  included in
conveying the object code work.

A  "User Product"  is either  (1) a  "consumer product",  which  means any
tangible personal property which is normally used for personal, family, or
household  purposes, or (2)  anything designed  or sold  for incorporation
into a dwelling.  In determining  whether a product is a consumer product,
doubtful cases shall  be resolved in favor of  coverage.  For a particular
product received by a particular user, "normally used" refers to a typical
or common  use of that class of  product, regardless of the  status of the
particular user or of the way  in which the particular user actually uses,
or expects  or is expected to use,  the product.  A product  is a consumer
product  regardless of  whether  the product  has substantial  commercial,
industrial  or non-consumer  uses,  unless such  uses  represent the  only
significant mode of use of the product.

"Installation  Information"   for  a  User  Product   means  any  methods,
procedures, authorization  keys, or other information  required to install
and execute modified versions of a  covered work in that User Product from
a  modified version  of its  Corresponding Source.   The  information must
suffice to  ensure that the  continued functioning of the  modified object
code  is  in   no  case  prevented  or  interfered   with  solely  because
modification has been made.

If  you convey an  object code  work under  this section  in, or  with, or
specifically for use in, a User  Product, and the conveying occurs as part
of a  transaction in  which the right  of possession  and use of  the User
Product is transferred to the recipient  in perpetuity or for a fixed term
(regardless of  how the  transaction is characterized),  the Corresponding
Source conveyed under this section must be accompanied by the Installation
Information.  But this  requirement does not apply if  neither you nor any
third party  retains the  ability to install  modified object code  on the
User Product (for example, the work has been installed in ROM).

The  requirement to provide  Installation Information  does not  include a
requirement to  continue to provide support service,  warranty, or updates
for a  work that has been modified  or installed by the  recipient, or for
the User Product in which it  has been modified or installed.  Access to a
network  may  be  denied  when  the  modification  itself  materially  and
adversely affects the  operation of the network or  violates the rules and
protocols for communication across the network.

Corresponding Source  conveyed, and Installation  Information provided, in
accord with this  section must be in a format  that is publicly documented
(and with an implementation available  to the public in source code form),
and  must require no  special password  or key  for unpacking,  reading or
copying.

   7. Additional Terms.

"Additional  permissions" are  terms  that supplement  the  terms of  this
License  by  making  exceptions  from  one  or  more  of  its  conditions.
Additional permissions that are applicable  to the entire Program shall be
treated as though  they were included in this License,  to the extent that
they are valid under applicable law.  If additional permissions apply only
to  part of  the Program,  that part  may be  used separately  under those
permissions,  but the  entire  Program remains  governed  by this  License
without regard to the additional permissions.

When you convey  a copy of a  covered work, you may at  your option remove
any  additional  permissions from  that  copy, or  from  any  part of  it.
(Additional permissions  may be  written to require  their own  removal in
certain  cases  when you  modify  the  work.)   You may  place  additional
permissions on  material, added by  you to a  covered work, for  which you
have or can give appropriate copyright permission.

Notwithstanding any other provision of  this License, for material you add
to a covered work, you may (if authorized by the copyright holders of that
material) supplement the terms of this License with terms:

a) Disclaiming  warranty or limiting liability differently  from the terms
   of sections 15 and 16 of this License; or

b) Requiring preservation of  specified reasonable legal notices or author
   attributions  in that  material  or in  the  Appropriate Legal  Notices
   displayed by works containing it; or

c) Prohibiting  misrepresentation  of  the  origin  of  that material,  or
   requiring  that  modified  versions  of  such  material  be  marked  in
   reasonable ways as different from the original version; or

d) Limiting the  use  for  publicity  purposes  of names  of licensors  or
   authors of the material; or

e) Declining  to grant rights  under trademark law  for use of  some trade
   names, trademarks, or service marks; or

f) Requiring indemnification of licensors  and authors of that material by
   anyone  who conveys  the material  (or  modified versions  of it)  with
   contractual  assumptions  of  liability   to  the  recipient,  for  any
   liability that  these contractual assumptions directly  impose on those
   licensors and authors.

All  other   non-permissive  additional  terms   are  considered  "further
restrictions" within  the meaning  of section 10.   If the Program  as you
received  it, or any  part of  it, contains  a notice  stating that  it is
governed by this License along with  a term that is a further restriction,
you  may remove  that  term.  If  a  license document  contains a  further
restriction but  permits relicensing or conveying under  this License, you
may add to  a covered work material governed by the  terms of that license
document,  provided that  the further  restriction does  not  survive such
relicensing or conveying.

If you add terms  to a covered work in accord with  this section, you must
place, in the  relevant source files, a statement  of the additional terms
that  apply to  those files,  or  a notice  indicating where  to find  the
applicable terms.

Additional terms, permissive or non-permissive,  may be stated in the form
of  a separately  written  license,  or stated  as  exceptions; the  above
requirements apply either way.

   8. Termination.

You  may  not propagate  or  modify a  covered  work  except as  expressly
provided under this License.  Any attempt otherwise to propagate or modify
it  is void,  and  will  automatically terminate  your  rights under  this
License (including  any patent licenses granted under  the third paragraph
of section 11).

However, if  you cease  all violation of  this License, then  your license
from a particular copyright holder is reinstated (a) provisionally, unless
and  until the  copyright holder  explicitly and  finally  terminates your
license, and (b) permanently, if  the copyright holder fails to notify you
of  the violation  by some  reasonable means  prior to  60 days  after the
cessation.

Moreover, your  license from a  particular copyright holder  is reinstated
permanently if the copyright holder  notifies you of the violation by some
reasonable  means, this  is the  first time  you have  received  notice of
violation of this  License (for any work) from  that copyright holder, and
you cure the violation prior to 30 days after your receipt of the notice.

Termination  of your  rights under  this  section does  not terminate  the
licenses of parties who have received copies or rights from you under this
License.   If  your  rights  have  been  terminated  and  not  permanently
reinstated,  you do  not  qualify to  receive  new licenses  for the  same
material under section 10.

   9. Acceptance Not Required for Having Copies.

You are not required  to accept this License in order to  receive or run a
copy of  the Program.  Ancillary  propagation of a covered  work occurring
solely as  a consequence of  using peer-to-peer transmission to  receive a
copy likewise  does not require  acceptance.  However, nothing  other than
this  License grants  you permission  to propagate  or modify  any covered
work.  These actions infringe copyright if you do not accept this License.
Therefore, by modifying  or propagating a covered work,  you indicate your
acceptance of this License to do so.

   10. Automatic Licensing of Downstream Recipients.

Each time you convey a  covered work, the recipient automatically receives
a license from  the original licensors, to run,  modify and propagate that
work,  subject to  this License.   You are  not responsible  for enforcing
compliance by third parties with this License.

An  "entity  transaction" is  a  transaction  transferring  control of  an
organization,  or  substantially all  assets  of  one,  or subdividing  an
organization, or merging organizations.   If propagation of a covered work
results from  an entity  transaction, each party  to that  transaction who
receives a  copy of the work  also receives whatever licenses  to the work
the party's predecessor  in interest had or could  give under the previous
paragraph, plus a  right to possession of the  Corresponding Source of the
work from  the predecessor in interest,  if the predecessor has  it or can
get it with reasonable efforts.

You may not impose any further  restrictions on the exercise of the rights
granted or affirmed under this License.  For example, you may not impose a
license fee, royalty, or other charge for exercise of rights granted under
this License, and you may not initiate litigation (including a cross-claim
or counterclaim in a lawsuit)  alleging that any patent claim is infringed
by making, using, selling, offering  for sale, or importing the Program or
any portion of it.

   11. Patents.

A  "contributor" is  a  copyright  holder who  authorizes  use under  this
License of the Program or a work  on which the Program is based.  The work
thus licensed is called the contributor's "contributor version".

A contributor's "essential  patent claims" are all patent  claims owned or
controlled  by  the contributor,  whether  already  acquired or  hereafter
acquired,  that would  be  infringed  by some  manner,  permitted by  this
License, of making, using, or  selling its contributor version, but do not
include claims  that would be infringed  only as a  consequence of further
modification of the contributor version.  For purposes of this definition,
"control"  includes the  right to  grant  patent sublicenses  in a  manner
consistent with the requirements of this License.

Each  contributor  grants  you  a non-exclusive,  worldwide,  royalty-free
patent license  under the contributor's essential patent  claims, to make,
use, sell, offer for sale,  import and otherwise run, modify and propagate
the contents of its contributor version.

In  the following  three paragraphs,  a  "patent license"  is any  express
agreement  or commitment,  however denominated,  not to  enforce  a patent
(such as an express permission to practice a patent or covenant not to sue
for patent  infringement).  To  "grant" such a  patent license to  a party
means to  make such  an agreement  or commitment not  to enforce  a patent
against the party.

If you convey  a covered work, knowingly relying on  a patent license, and
the Corresponding Source of the work  is not available for anyone to copy,
free of  charge and under  the terms of  this License, through  a publicly
available network server or other  readily accessible means, then you must
either  (1) cause  the Corresponding  Source to  be so  available,  or (2)
arrange to deprive yourself of the  benefit of the patent license for this
particular  work,  or  (3)  arrange,  in  a  manner  consistent  with  the
requirements of this  License, to extend the patent  license to downstream
recipients.  "Knowingly relying" means you have actual knowledge that, but
for the patent  license, your conveying the covered work  in a country, or
your recipient's use of the covered  work in a country, would infringe one
or  more identifiable  patents in  that country  that you  have  reason to
believe are valid.

If, pursuant to or in connection with a single transaction or arrangement,
you convey, or  propagate by procuring conveyance of,  a covered work, and
grant a patent  license to some of the parties  receiving the covered work
authorizing them  to use, propagate, modify  or convey a  specific copy of
the  covered work,  then the  patent  license you  grant is  automatically
extended to all recipients of the covered work and works based on it.

A patent  license is  "discriminatory" if it  does not include  within the
scope of its coverage, prohibits the exercise of, or is conditioned on the
non-exercise of  one or more of  the rights that  are specifically granted
under this License.  You may not convey  a covered work if you are a party
to  an  arrangement  with  a  third  party that  is  in  the  business  of
distributing software,  under which  you make payment  to the  third party
based on  the extent  of your  activity of conveying  the work,  and under
which the third party grants, to  any of the parties who would receive the
covered work from  you, a discriminatory patent license  (a) in connection
with copies of the covered work conveyed by you (or copies made from those
copies), or (b) primarily for  and in connection with specific products or
compilations that contain  the covered work, unless you  entered into that
arrangement, or that patent license was granted, prior to 28 March 2007.

Nothing in  this License shall be  construed as excluding  or limiting any
implied license  or other defenses  to infringement that may  otherwise be
available to you under applicable patent law.

   12. No Surrender of Others' Freedom.

If 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 convey a
covered work so  as to satisfy simultaneously your  obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey  it at all.  For example,  if you agree to  terms that obligate
you to  collect a  royalty for  further conveying from  those to  whom you
convey the  Program, the only way  you could satisfy both  those terms and
this License would be to refrain entirely from conveying the Program.

   13. Use with the GNU Affero General Public License.

Notwithstanding any  other provision of this License,  you have permission
to link or  combine any covered work with a work  licensed under version 3
of the GNU Affero General Public  License into a single combined work, and
to convey the resulting work.  The  terms of this License will continue to
apply to the part which is  the covered work, but the special requirements
of  the  GNU  Affero   General  Public  License,  section  13,  concerning
interaction through a network will apply to the combination as such.

   14. Revised Versions of this License.

The Free  Software Foundation may  publish revised and/or new  versions of
the GNU 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  that a  certain  numbered  version of  the  GNU General  Public
License  "or any  later version"  applies to  it, you  have the  option of
following the terms  and conditions either of that  numbered version or of
any  later version  published by  the  Free Software  Foundation.  If  the
Program  does not  specify  a version  number  of the  GNU General  Public
License, you  may choose any version  ever published by  the Free Software
Foundation.

If the Program specifies that a  proxy can decide which future versions of
the GNU General Public License  can be used, that proxy's public statement
of  acceptance of  a version  permanently  authorizes you  to choose  that
version for the Program.

Later license  versions may give you additional  or different permissions.
However, no additional obligations are  imposed on any author or copyright
holder as a result of your choosing to follow a later version.

   15. Disclaimer of Warranty.

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.

   16. Limitation of Liability.

IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
ANY COPYRIGHT HOLDER,  OR ANY OTHER PARTY WHO  MODIFIES AND/OR CONVEYS 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.

   17. Interpretation of Sections 15 and 16.

If the disclaimer  of warranty and limitation of  liability provided above
cannot be  given local  legal effect according  to their  terms, reviewing
courts shall  apply local law  that most closely approximates  an absolute
waiver of  all civil  liability in connection  with the Program,  unless a
warranty or assumption  of liability accompanies a copy  of the Program in
return for a fee.

	      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 state 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 3 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, see <http://www.gnu.org/licenses/>.

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

If the  program does terminal interaction,  make it output  a short notice
like this when it starts in an interactive mode:

   <program>  Copyright (C) <year>,  <name of author>
   This program 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,  your
program's commands might be different;  for a GUI interface, you would use
an "about box".

You should also get your employer (if you work as a programmer) or school,
if any,  to sign a "copyright  disclaimer" for the  program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.

The GNU 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 Lesser
General Public  License instead of  this License.  But first,  please read
