	108
	109	2.3. Limitations on Grant Scope
	110
	111	The licenses granted in this Section 2 are the only rights granted under
	112	this License. No additional rights or licenses will be implied from the
	113	distribution or licensing of Covered Software under this License.
	114	Notwithstanding Section 2.1(b) above, no patent license is granted by a
	115	Contributor:
	116
	117	(a) for any code that a Contributor has removed from Covered Software;

	123	Version); or
	124
	125	(c) under Patent Claims infringed by Covered Software in the absence of
	126	its Contributions.
	127
	128	This License does not grant any rights in the trademarks, service marks,
	129	or logos of any Contributor (except as may be necessary to comply with
	130	the notice requirements in Section 3.4).
	131
	132	2.4. Subsequent Licenses
	133
	134	No Contributor makes additional grants as a result of Your choice to
	135	distribute the Covered Software under a subsequent version of this
	136	License (see Section 10.2) or under the terms of a Secondary License (if
	137	permitted under the terms of Section 3.3).
	138
	139	2.5. Representation

	143	to grant the rights to its Contributions conveyed by this License.
	144
	145	2.6. Fair Use
	146
	147	This License is not intended to limit any rights You have under

	150
	151	2.7. Conditions
	152
	153	Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted

	155
	156	3. Responsibilities
	157	-------------------
	158
	159	3.1. Distribution of Source Form
	160
	161	All distribution of Covered Software in Source Code Form, including any
	162	Modifications that You create or to which You contribute, must be under
	163	the terms of this License. You must inform recipients that the Source
	164	Code Form of the Covered Software is governed by the terms of this
	165	License, and how they can obtain a copy of this License. You may not
	166	attempt to alter or restrict the recipients' rights in the Source Code
	167	Form.
	168
	169	3.2. Distribution of Executable Form
	170
	171	If You distribute Covered Software in Executable Form then:
	172
	173	(a) such Covered Software must also be made available in Source Code
	174	Form, as described in Section 3.1, and You must inform recipients of
	175	the Executable Form how they can obtain a copy of such Source Code
	176	Form by reasonable means in a timely manner, at a charge no more
	177	than the cost of distribution to the recipient; and
	178
	179	(b) You may distribute such Executable Form under the terms of this
	180	License, or sublicense it under different terms, provided that the
	181	license for the Executable Form does not attempt to limit or alter
	182	the recipients' rights in the Source Code Form under this License.
	183
	184	3.3. Distribution of a Larger Work
	185
	186	You may create and distribute a Larger Work under terms of Your choice,
	187	provided that You also comply with the requirements of this License for
	188	the Covered Software. If the Larger Work is a combination of Covered
	189	Software with a work governed by one or more Secondary Licenses, and the
	190	Covered Software is not Incompatible With Secondary Licenses, this
	191	License permits You to additionally distribute such Covered Software
	192	under the terms of such Secondary License(s), so that the recipient of
	193	the Larger Work may, at their option, further distribute the Covered
	194	Software under the terms of either this License or such Secondary
	195	License(s).
	196
	197	3.4. Notices
	198
	199	You may not remove or alter the substance of any license notices
	200	(including copyright notices, patent notices, disclaimers of warranty,
	201	or limitations of liability) contained within the Source Code Form of
	202	the Covered Software, except that You may alter any license notices to
	203	the extent required to remedy known factual inaccuracies.
	204
	205	3.5. Application of Additional Terms
	206
	207	You may choose to offer, and to charge a fee for, warranty, support,
	208	indemnity or liability obligations to one or more recipients of Covered
	209	Software. However, You may do so only on Your own behalf, and not on
	210	behalf of any Contributor. You must make it absolutely clear that any
	211	such warranty, support, indemnity, or liability obligation is offered by
	212	You alone, and You hereby agree to indemnify every Contributor for any
	213	liability incurred by such Contributor as a result of warranty, support,
	214	indemnity or liability terms You offer. You may include additional
	215	disclaimers of warranty and limitations of liability specific to any
	216	jurisdiction.
	217
	218	4. Inability to Comply Due to Statute or Regulation
	219	---------------------------------------------------
	220
	221	If it is impossible for You to comply with any of the terms of this
	222	License with respect to some or all of the Covered Software due to
	223	statute, judicial order, or regulation then You must: (a) comply with
	224	the terms of this License to the maximum extent possible; and (b)
	225	describe the limitations and the code they affect. Such description must
	226	be placed in a text file included with all distributions of the Covered
	227	Software under this License. Except to the extent prohibited by statute
	228	or regulation, such description must be sufficiently detailed for a
	229	recipient of ordinary skill to be able to understand it.
	230
	231	5. Termination
	232	--------------
	233
	234	5.1. The rights granted under this License will terminate automatically
	235	if You fail to comply with any of its terms. However, if You become
	236	compliant, then the rights granted under this License from a particular
	237	Contributor are reinstated (a) provisionally, unless and until such
	238	Contributor explicitly and finally terminates Your grants, and (b) on an
	239	ongoing basis, if such Contributor fails to notify You of the
	240	non-compliance by some reasonable means prior to 60 days after You have
	241	come back into compliance. Moreover, Your grants from a particular
	242	Contributor are reinstated on an ongoing basis if such Contributor
	243	notifies You of the non-compliance by some reasonable means, this is the
	244	first time You have received notice of non-compliance with this License
	245	from such Contributor, and You become compliant prior to 30 days after
	246	Your receipt of the notice.
	247
	248	5.2. If You initiate litigation against any entity by asserting a patent
	249	infringement claim (excluding declaratory judgment actions,
	250	counter-claims, and cross-claims) alleging that a Contributor Version
	251	directly or indirectly infringes any patent, then the rights granted to
	252	You by any and all Contributors for the Covered Software under Section
	253	2.1 of this License shall terminate.
	254
	255	5.3. In the event of termination under Sections 5.1 or 5.2 above, all
	256	end user license agreements (excluding distributors and resellers) which
	257	have been validly granted by You or Your distributors under this License
	258	prior to termination shall survive termination.

	302	8. Litigation
	303	-------------
	304
	305	Any litigation relating to this License may be brought only in the

4		Please refer to the mods individual README for more information.
	2	## Developed by the Eurythmia team
	3
	4	This mod is an API for registering throwing and throwable things.
	5
	6	Mods based on this API:
	7	* [throwing_arrows](https://github.com/minetest-mods/throwing_arrows) is a compatible replacement for the throwing mod by PilzAdam.
	8	* [sling](https://github.com/minetest-mods/sling) is a mod written by @tacotexmex that enables item stack and single item throwing of any item.
	9	* [Native American Village](https://github.com/Steamed-Punk/Native-American-Village), by Steamed-Punk, adds, among many other various items, a tomahawk that can be thrown.
	10
	11	## Configuration
	12
	13	The settings are the following:
	14	```
	15	# Trajectory parameters
	16	throwing.vertical_acceleration = -10
	17	throwing.realistic_trajectory = false
	18	throwing.frictional_coefficient = -.5
	19
	20	# How the initial velocity of arrows is computed: simple, strength, or momentum
	21	throwing.velocity_mode = strength
	22	throwing.velocity_factor = 19
	23
	24	# Whether to allow placing an arrow as a node
	25	throwing.allow_arrow_placing = false
	26
	27	# Minimum time between two shots
	28	throwing.bow_cooldown = 0.2
	29
	30	# Whether to enable toolranks for bows
	31	throwing.toolranks = true
	32	```
	33
	34	### Trajectory parameters
	35
	36	By default, the trajectory of the arrow is a simple parabola. You can set the vertical acceleration (acceleration of gravity) using `throwing.vertical_acceleration`.
	37
	38	If you want a more realistic trajectory that uses a first-order modelling of air friction, you can set `throwing.realistic_trajectory` to true. In this mode, `throwing.frictional_coefficient` indicates the ratio between the friction force on the arrow and its velocity. It should be negative. The acceleration of the arrow is subsequently determined by dividing the force by the "mass" of the arrow, the reference mass of 1 being the mass of a simple steel arrow. Generally, the frictional coefficient should be quite small; a value of -1 will already drastically shorten the range of the arrow. The default is -0.5.
	39
	40	### Initial velocity computation
	41
	42	The mod provides three modes to compute the initial speed of an arrow: simple, strength or strengthmass.
	43
	44	In simple mode, the initial velocity of the arrow is always the same. The `throwing.velocity_factor` contains the value of this velocity.
	45
	46	In strength mode (the default), the initial velocity of the arrow only depends on the bow that is used---the more expensive the bow, the faster the arrow. The arrow strength is multiplied by the velocity factor to compute the speed of the arrow, an arrow strength of 1 is about the strength of the steel bow in `throwing_arrows`.
	47
	48	Finally, momentum mode is the most realistic. It computes the velocity of the arrow based on the bow strength, as in the strength mode, and on the mass of the arrow: the heavier the arrow, the slower it will be shot. It is called the momentum mode because, in this mode, the strength of a bow indicates the initial momentum of the arrow rather than its initial speed.
	49
	50	## API
	51
	52	There are two available functions in the mod API:
	53	```lua
	54	function throwing.register_bow(name, definition)
	55	--[[
	56	Name: Bow name. If it doesn't contain ":", the "throwing:" prefix will be added.
	57	Definition: definition table, containing:
	58	* description (highly recommended): description of the bow.
	59	* texture (essential): texture of the bow, shown in inventory.
	60	* groups (optional): groups of the item.
	61	* uses: number of uses of the bow (the default is 50).
	62	* allow_shot (optional): function(player, itemstack, index, last_run):
	63	- player: the player using the bow
	64	- itemstack: the itemstack of the bow
	65	- index: index of the arrow in the inventory
	66	- last_run: whether this is the last time this function is called before actually calling `spawn_arrow_entity`.
	67	Currently, `allow_shot` is actually run twice (once before the delay, and once after).
	68	- should return true if the shot can be made, and false otherwise
	69	- the default function checks that the arrow to be thrown is a registered arrow
	70	- it can return a second return value, which is the new itemstack to replace the arrow after the shot
	71	* throw_itself (optional): whether the bow should throw itself instead of the arrow next to it in the inventory.
	72	The default is false.
	73	* cooldown: bow cooldown. Default is setting throwing.bow_cooldown
	74	* function spawn_arrow_entity(position, arrow, player): defaults to throwing.spawn_arrow_entity
	75	* sound: sound to be played when the bow is used
	76	* delay: delay before throwing the arrow
	77	* no_toolranks: If true, toolranks support is disabled for this item. Defaults to false.
	78	]]
	79
	80	-- Example:
	81	throwing.register_bow("bow_wood", {
	82	itemcraft = "default:wood",
	83	description = "Wooden Bow",
	84	texture = "throwing_bow_wood.png"
	85	})
	86
	87	itemcraft, craft_quantity, description, tiles, on_hit_sound, on_hit[, on_throw[, groups]]
	88	function throwing.register_arrow(name, definition table)
	89	--[[
	90	Name: Arrow name. If it doesn't contain ":", the "throwing:" prefix will be added.
	91	Definition: definition table, containing:
	92	* tiles (essential): tiles of the arrow.
	93	* target (optional, defaulting to throwing.target_both): what the arrow is able to hit (throwing.target_node, throwing.target_object, throwing.target_both).
	94	* allow_protected (optional, defaulting to false): whether the arrow can be throw in a protected area
	95	* on_hit_sound (optional): sound played when the arrow hits a node or an object.
	96	* on_hit(self, pos, last_pos, node, object, hitter, data) (optional but very useful): callback function:
	97	- pos: the position of the hit node or object.
	98	- last_pos: the last air node where the arrow was
	99	- node and object: hit node or object. Either node or object is nil, depending
	100	whether the arrow hit a node or an object.
	101	- hitter: an ObjectRef to the thrower player.
	102	- data: a data table associated to the entity where you can store what you want
	103	- self: the arrow entity table (it allows you to hack a lot!)
	104	- If it fails, it should return:

	135	Otherwise, if its definition contains a `throwing_entity` field, this field will be used as the entity name if it is a string, otherwise it will be called as a `function(pos, player)` that has to spawn the object and return the corresponding ObjectRef.
	136	If the item is neither an arrow nor has a `throwing_entity` field, the corresponding `__builtin:item` will be used.

108
109		2.3. Limitations on Grant Scope
110
111		The licenses granted in this Section 2 are the only rights granted under
112		this License. No additional rights or licenses will be implied from the
113		distribution or licensing of Covered Software under this License.
114		Notwithstanding Section 2.1(b) above, no patent license is granted by a
115		Contributor:
116
117		(a) for any code that a Contributor has removed from Covered Software;
118		or
119
120		(b) for infringements caused by: (i) Your and any other third party's
121		modifications of Covered Software, or (ii) the combination of its

123		Version); or
124
125		(c) under Patent Claims infringed by Covered Software in the absence of
126		its Contributions.
127
128		This License does not grant any rights in the trademarks, service marks,
129		or logos of any Contributor (except as may be necessary to comply with
130		the notice requirements in Section 3.4).
131
132		2.4. Subsequent Licenses
133
134		No Contributor makes additional grants as a result of Your choice to
135		distribute the Covered Software under a subsequent version of this
136		License (see Section 10.2) or under the terms of a Secondary License (if
137		permitted under the terms of Section 3.3).
138
139		2.5. Representation

146
147		This License is not intended to limit any rights You have under

150
151		2.7. Conditions
152
153		Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted

155
156		3. Responsibilities
157		-------------------
158
159		3.1. Distribution of Source Form
160
161		All distribution of Covered Software in Source Code Form, including any
162		Modifications that You create or to which You contribute, must be under
163		the terms of this License. You must inform recipients that the Source
164		Code Form of the Covered Software is governed by the terms of this
165		License, and how they can obtain a copy of this License. You may not
166		attempt to alter or restrict the recipients' rights in the Source Code
167		Form.
168
169		3.2. Distribution of Executable Form
170
171		If You distribute Covered Software in Executable Form then:
172
173		(a) such Covered Software must also be made available in Source Code
174		Form, as described in Section 3.1, and You must inform recipients of
175		the Executable Form how they can obtain a copy of such Source Code
176		Form by reasonable means in a timely manner, at a charge no more
177		than the cost of distribution to the recipient; and
178
179		(b) You may distribute such Executable Form under the terms of this
180		License, or sublicense it under different terms, provided that the
181		license for the Executable Form does not attempt to limit or alter
182		the recipients' rights in the Source Code Form under this License.
183
184		3.3. Distribution of a Larger Work
185
186		You may create and distribute a Larger Work under terms of Your choice,
187		provided that You also comply with the requirements of this License for
188		the Covered Software. If the Larger Work is a combination of Covered
189		Software with a work governed by one or more Secondary Licenses, and the
190		Covered Software is not Incompatible With Secondary Licenses, this
191		License permits You to additionally distribute such Covered Software
192		under the terms of such Secondary License(s), so that the recipient of
193		the Larger Work may, at their option, further distribute the Covered
194		Software under the terms of either this License or such Secondary
195		License(s).
196
197		3.4. Notices
198
199		You may not remove or alter the substance of any license notices
200		(including copyright notices, patent notices, disclaimers of warranty,
201		or limitations of liability) contained within the Source Code Form of
202		the Covered Software, except that You may alter any license notices to
203		the extent required to remedy known factual inaccuracies.
204
205		3.5. Application of Additional Terms
206
207		You may choose to offer, and to charge a fee for, warranty, support,
208		indemnity or liability obligations to one or more recipients of Covered
209		Software. However, You may do so only on Your own behalf, and not on
210		behalf of any Contributor. You must make it absolutely clear that any
211		such warranty, support, indemnity, or liability obligation is offered by
212		You alone, and You hereby agree to indemnify every Contributor for any
213		liability incurred by such Contributor as a result of warranty, support,
214		indemnity or liability terms You offer. You may include additional
215		disclaimers of warranty and limitations of liability specific to any
216		jurisdiction.
217
218		4. Inability to Comply Due to Statute or Regulation
219		---------------------------------------------------
220
221		If it is impossible for You to comply with any of the terms of this
222		License with respect to some or all of the Covered Software due to
223		statute, judicial order, or regulation then You must: (a) comply with
224		the terms of this License to the maximum extent possible; and (b)
225		describe the limitations and the code they affect. Such description must
226		be placed in a text file included with all distributions of the Covered
227		Software under this License. Except to the extent prohibited by statute
228		or regulation, such description must be sufficiently detailed for a
229		recipient of ordinary skill to be able to understand it.
230
231		5. Termination
232		--------------
233
234		5.1. The rights granted under this License will terminate automatically
235		if You fail to comply with any of its terms. However, if You become
236		compliant, then the rights granted under this License from a particular
237		Contributor are reinstated (a) provisionally, unless and until such
238		Contributor explicitly and finally terminates Your grants, and (b) on an
239		ongoing basis, if such Contributor fails to notify You of the
240		non-compliance by some reasonable means prior to 60 days after You have
241		come back into compliance. Moreover, Your grants from a particular
242		Contributor are reinstated on an ongoing basis if such Contributor
243		notifies You of the non-compliance by some reasonable means, this is the
244		first time You have received notice of non-compliance with this License
245		from such Contributor, and You become compliant prior to 30 days after
246		Your receipt of the notice.
247
248		5.2. If You initiate litigation against any entity by asserting a patent
249		infringement claim (excluding declaratory judgment actions,
250		counter-claims, and cross-claims) alleging that a Contributor Version
251		directly or indirectly infringes any patent, then the rights granted to
252		You by any and all Contributors for the Covered Software under Section
253		2.1 of this License shall terminate.
254
255		5.3. In the event of termination under Sections 5.1 or 5.2 above, all
256		end user license agreements (excluding distributors and resellers) which
257		have been validly granted by You or Your distributors under this License
258		prior to termination shall survive termination.

344		any references to the name of the license steward (except to note that
345		such modified license differs from this License).
346
347		10.4. Distributing Source Code Form that is Incompatible With Secondary

0		# Throwing
1
2		## Developed by the Eurythmia team
3
4		This mod is an API for registering throwing and throwable things.
5
6		Mods based on this API:
7		* [throwing_arrows](https://github.com/MT-Eurythmia/throwing/tree/master/throwing_arrows) is a compatible replacement for the throwing mod by PilzAdam.
8		* [sling](https://github.com/tacotexmex/sling) is a mod written by @tacotexmex that enables item stack and single item throwing of any item.
9
10		## Configuration
11
12		The settings are the following:
13		```
14		throwing.velocity_factor = 19
15		throwing.horizontal_acceleration_factor = -3
16		throwing.vertical_acceleration = -10
17
18		throwing.allow_arrow_placing = false
19
20		throwing.bow_cooldown = 0.2
21		```
22
23		## API
24
25		There are two available functions in the mod API:
26		```lua
27		function throwing.register_bow(name, definition)
28		--[[
29		Name: Bow name. If it doesn't contain ":", the "throwing:" prefix will be added.
30		Definition: definition table, containing:
31		* itemcraft (optional, you may want to register your own craft or to make the bow uncraftable): item used to craft the bow.
32		* description (highly recommended): description of the bow.
33		* texture (essential): texture of the bow, shown in inventory.
34		* groups (optional): groups of the item.
35		* uses: number of uses of the bow (default is 50).
36		* allow_shot (optional): function(player, itemstack, index, last_run):
37		- player: the player using the bow
38		- itemstack: the itemstack of the bow
39		- index: index of the arrow in the inventory
40		- last_run: whether this is the last time this function is called before actually calling `spawn_arrow_entity`.
41		Currently, `allow_shot` is actually run twice (once before the delay, and once after).
42		- should return true if the shot can be made, and false otherwise
43		- the default function checks that the arrow to be thrown is a registered arrow
44		- it can return a second return value, which is the new itemstack
45		* throw_itself (optional): whether the bow should throw itself instead of the arrow next to it in the inventory.
46		If present, allow_shot is ignored.
47		Default is false.
48		Warning: this field is not known to be currently used by a mod. If you encounter bugs using it, please open
49		an issue!
50		* cooldown: bow cooldown. Default is setting throwing.bow_cooldown
51		* function spawn_arrow_entity(position, arrow, player): defaults to throwing.spawn_arrow_entity
52		* sound: sound to be played when the bow is used
53		* delay: delay before throwing the arrow
54		]]
55
56		-- Example:
57		throwing.register_bow("bow_wood", {
58		itemcraft = "default:wood",
59		description = "Wooden Bow",
60		texture = "throwing_bow_wood.png"
61		})
62
63		itemcraft, craft_quantity, description, tiles, on_hit_sound, on_hit[, on_throw[, groups]]
64		function throwing.register_arrow(name, definition table)
65		--[[
66		Name: Arrow name. If it doesn't contain ":", the "throwing:" prefix will be added.
67		Definition: definition table, containing:
68		* itemcraft (optional, you may want to register your own craft or to make the arrow uncraftable): item used to craft the arrow.
69		* craft_quantity (optional, defaulting to 1 if itemcraft is non-nil, pointless otherwise): quantity of arrows in the craft output.
70		* tiles (essential): tiles of the arrow.
71		* target (optional, defaulting to throwing.target_both): what the arrow is able to hit (throwing.target_node, throwing.target_object, throwing.target_both).
72		* allow_protected (optional, defaulting to false): whether the arrow can be throw in a protected area
73		* on_hit_sound (optional): sound played when the arrow hits a node or an object.
74		* on_hit(self, pos, last_pos, node, object, hitter, data) (optional but very useful): callback function:
75		- pos: the position of the hit node or object.
76		- last_pos: the last air node where the arrow was
77		- node and object: hit node or object. Either node or object is nil, depending
78		whether the arrow hit a node or an object.
79		- hitter: an ObjectRef to the thrower player.
80		- data: a data table associated to the entity where you can store what you want
81		- self: the arrow entity table (it allows you to hack a lot!)
82		- If it fails, it should return:
83		false[, reason]
84		* on_throw(self, pos, thrower, itemstack, index, data) (optional): callback function: on_throw:
85		- pos: the position from where the arrow is throw (which a bit higher than the hitter position)
86		- thrower: an ObjectRef to the thrower player
87		- next_index: the index next to the arrow in the "main" inventory
88		- data: a data table associated to the entity where you can store what you want
89		- self: the arrow entity table
90		- If the arrow shouldn't be thrown, it should return false.
91		* on_throw_sound (optional, there is a default sound, specify "" for no sound): sound to be played when the arrow is throw
92		* on_hit_fails(self, pos, thrower, data) (optional): callback function called if the hit failed (e.g. because on_hit returned false or because the area was protected)
93		]]
94
95		-- Example:
96		throwing.register_arrow("arrow", {
97		itemcraft = "default:steel_ingot",
98		craft_quantity = 16,
99		description = "Arrow",
100		tiles = {"throwing_arrow.png", "throwing_arrow.png", "throwing_arrow_back.png", "throwing_arrow_front.png", "throwing_arrow_2.png", "throwing_arrow.png"},
101		target = throwing.target_object,
102		on_hit_sound = "throwing_arrow",
103		on_hit = function(pos, _, _, object, hitter)
104		object:punch(hitter, 1, {
105		full_punch_interval = 1,
106		damage_groups = {fleshy = 3}
107		})
108		end
109		})
110		```
111
112		If the item to throw is an arrow registered using `throwing.register_arrow`, the entity used will be the entity automatically registered by this function.
113		Otherwise, if its definition contains a `throwing_entity` field, this field will be used as the entity name if it is a string, otherwise it will be called as a `function(pos, player)` that has to spawn the object and return the corresponding ObjectRef.
114		If the item is neither an arrow nor has a `throwing_entity` field, the corresponding `__builtin:item` will be used.

125		(c) under Patent Claims infringed by Covered Software in the absence of
126		its Contributions.
127
128		This License does not grant any rights in the trademarks, service marks,
129		or logos of any Contributor (except as may be necessary to comply with
130		the notice requirements in Section 3.4).
131
132		2.4. Subsequent Licenses
133
134		No Contributor makes additional grants as a result of Your choice to
135		distribute the Covered Software under a subsequent version of this
136		License (see Section 10.2) or under the terms of a Secondary License (if
137		permitted under the terms of Section 3.3).
138
139		2.5. Representation
140
141		Each Contributor represents that the Contributor believes its
142		Contributions are its original creation(s) or it has sufficient rights
143		to grant the rights to its Contributions conveyed by this License.
144
145		2.6. Fair Use
146
147		This License is not intended to limit any rights You have under
148		applicable copyright doctrines of fair use, fair dealing, or other
149		equivalents.
150
151		2.7. Conditions
152
153		Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
154		in Section 2.1.
155
156		3. Responsibilities
157		-------------------
158
159		3.1. Distribution of Source Form
160
161		All distribution of Covered Software in Source Code Form, including any
162		Modifications that You create or to which You contribute, must be under
163		the terms of this License. You must inform recipients that the Source
164		Code Form of the Covered Software is governed by the terms of this
165		License, and how they can obtain a copy of this License. You may not
166		attempt to alter or restrict the recipients' rights in the Source Code
167		Form.
168
169		3.2. Distribution of Executable Form
170
171		If You distribute Covered Software in Executable Form then:
172
173		(a) such Covered Software must also be made available in Source Code
174		Form, as described in Section 3.1, and You must inform recipients of
175		the Executable Form how they can obtain a copy of such Source Code
176		Form by reasonable means in a timely manner, at a charge no more
177		than the cost of distribution to the recipient; and
178
179		(b) You may distribute such Executable Form under the terms of this
180		License, or sublicense it under different terms, provided that the
181		license for the Executable Form does not attempt to limit or alter
182		the recipients' rights in the Source Code Form under this License.
183
184		3.3. Distribution of a Larger Work
185
186		You may create and distribute a Larger Work under terms of Your choice,
187		provided that You also comply with the requirements of this License for
188		the Covered Software. If the Larger Work is a combination of Covered
189		Software with a work governed by one or more Secondary Licenses, and the
190		Covered Software is not Incompatible With Secondary Licenses, this
191		License permits You to additionally distribute such Covered Software
192		under the terms of such Secondary License(s), so that the recipient of
193		the Larger Work may, at their option, further distribute the Covered
194		Software under the terms of either this License or such Secondary
195		License(s).
196
197		3.4. Notices
198
199		You may not remove or alter the substance of any license notices
200		(including copyright notices, patent notices, disclaimers of warranty,
201		or limitations of liability) contained within the Source Code Form of
202		the Covered Software, except that You may alter any license notices to
203		the extent required to remedy known factual inaccuracies.
204
205		3.5. Application of Additional Terms
206
207		You may choose to offer, and to charge a fee for, warranty, support,
208		indemnity or liability obligations to one or more recipients of Covered
209		Software. However, You may do so only on Your own behalf, and not on
210		behalf of any Contributor. You must make it absolutely clear that any
211		such warranty, support, indemnity, or liability obligation is offered by
212		You alone, and You hereby agree to indemnify every Contributor for any
213		liability incurred by such Contributor as a result of warranty, support,
214		indemnity or liability terms You offer. You may include additional
215		disclaimers of warranty and limitations of liability specific to any
216		jurisdiction.
217
218		4. Inability to Comply Due to Statute or Regulation
219		---------------------------------------------------
220
221		If it is impossible for You to comply with any of the terms of this
222		License with respect to some or all of the Covered Software due to
223		statute, judicial order, or regulation then You must: (a) comply with
224		the terms of this License to the maximum extent possible; and (b)
225		describe the limitations and the code they affect. Such description must
226		be placed in a text file included with all distributions of the Covered
227		Software under this License. Except to the extent prohibited by statute
228		or regulation, such description must be sufficiently detailed for a
229		recipient of ordinary skill to be able to understand it.
230
231		5. Termination
232		--------------
233
234		5.1. The rights granted under this License will terminate automatically
235		if You fail to comply with any of its terms. However, if You become
236		compliant, then the rights granted under this License from a particular
237		Contributor are reinstated (a) provisionally, unless and until such
238		Contributor explicitly and finally terminates Your grants, and (b) on an
239		ongoing basis, if such Contributor fails to notify You of the
240		non-compliance by some reasonable means prior to 60 days after You have
241		come back into compliance. Moreover, Your grants from a particular
242		Contributor are reinstated on an ongoing basis if such Contributor
243		notifies You of the non-compliance by some reasonable means, this is the
244		first time You have received notice of non-compliance with this License
245		from such Contributor, and You become compliant prior to 30 days after
246		Your receipt of the notice.
247
248		5.2. If You initiate litigation against any entity by asserting a patent
249		infringement claim (excluding declaratory judgment actions,
250		counter-claims, and cross-claims) alleging that a Contributor Version
251		directly or indirectly infringes any patent, then the rights granted to
252		You by any and all Contributors for the Covered Software under Section
253		2.1 of this License shall terminate.
254
255		5.3. In the event of termination under Sections 5.1 or 5.2 above, all
256		end user license agreements (excluding distributors and resellers) which
257		have been validly granted by You or Your distributors under this License
258		prior to termination shall survive termination.
