       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	 soft-
       ware--to	 make  sure the	software is free for all its users.  This Gen-
       eral 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 pro-
       grams, 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 ser-
       vice  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 dis-
       tribute 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 soft-
       ware.   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  pro-
       prietary.   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  modifi-
       cation 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  run-
       ning  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 Pro-
       gram.

       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 stat-
	   ing 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 identifi-
       able 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 collec-
       tive 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	inter-
	   change; 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-read-
	   able	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,  par-
       ties  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 pro-
       hibited by law if you do	not accept this	License.  Therefore, by	 modi-
       fying  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 orig-
       inal 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 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  dis-
       tribute	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 circum-
       stances.

       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	imple-
       mented 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  cer-
       tain  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 limita-
       tion 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	condi-
       tions 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  WAR-
       RANTY  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 WRIT-
       ING WILL	ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY	AND/OR
       REDISTRIBUTE THE	PROGRAM	AS PERMITTED ABOVE, BE LIABLE TO YOU FOR  DAM-
       AGES,  INCLUDING	ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAM-
       AGES 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













	       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 mod-
	   ify it under	the terms of the GNU General Public  License  as  pub-
	   lished  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 MER-
	   CHANTABILITY	or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU Gen-
	   eral	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 Founda-
	   tion, 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	redis-
	   tribute it under certain conditions;	type `show c' for details.

       The  hypothetical commands `show	w' and `show c'	should show the	appro-
       priate 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 pro-
	   gram	`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 applica-
       tions with the library.	If this	is what	you want to do,	 use  the  GNU
       Library General Public License instead of this License.
