	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.

	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
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.

	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
