       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 free-
       dom 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  free-
       dom,  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 modi-
       fied 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 redis-
       tributors 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 trans-
       lated 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	modifica-
       tion 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	(indepen-
       dent 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 Pro-
       gram's source code as you receive it, in	any medium,  pro-
       vided  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 protec-
       tion 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 Pro-
       gram, 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  pub-
	   lish,  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 inter-
	   actively  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  Pro-
	   gram	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 dis-
       tribute 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  cus-
	   tomarily 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	customar-
	   ily 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  compi-
       lation  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  (com-
       piler, kernel, and so on) of the	operating system on which
       the executable runs, unless that	component itself accompa-
       nies 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  dis-
       tribute the Program is void, and	will automatically termi-
       nate 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 per-
       mission to modify or distribute the Program or its deriva-
       tive works.  These actions are prohibited by law	if you do
       not  accept this	License.  Therefore, by	modifying or dis-
       tributing 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 restric-
       tions 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 lim-
       ited to patent issues),	conditions  are	 imposed  on  you
       (whether	by court order,	agreement or otherwise)	that con-
       tradict 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  obliga-
       tions  under  this License and any other	pertinent obliga-
       tions, 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 distri-
       bution of the Program.

       If any portion of this section is held  invalid	or  unen-
       forceable  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 soft-
       ware  distribution  system, which is implemented	by public
       license practices.  Many	people have made generous contri-
       butions	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 coun-
       tries, 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 dif-
       ferent, write to	the author to ask  for	permission.   For
       software	which is copyrighted by	the Free Software Founda-
       tion, 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 deriva-
       tives  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  PRO-
       GRAM 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, INCLUD-
       ING ANY GENERAL,	SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAM-
       AGES  ARISING  OUT OF THE USE OR	INABILITY TO USE THE PRO-
       GRAM (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



	Appendix: 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) 19yy <	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 Foun-
	   dation;  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, 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) 19yy 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  condi-
	   tions; 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 pro-
       grammer)	or your	school,	if any,	to sign	a "copyright dis-
       claimer"	for the	program, if necessary.	Here is	a sample;
       alter the names:

	   Yoyodyne, Inc., hereby disclaims all	copyright  inter-
	   est	in  the	program	`Gnomovision' (which makes passes
	   at compilers) written by James Hacker.

       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.
