	2. License Grants and Conditions
	--------------------------------

	2.1. Grants

	Each Contributor hereby grants You a world-wide, royalty-free,
	non-exclusive license:

	(a) under intellectual property rights (other than patent or trademark)
	    Licensable by such Contributor to use, reproduce, make available,
	    modify, display, perform, distribute, and otherwise exploit its
	    Contributions, either on an unmodified basis, with Modifications, or
	    as part of a Larger Work; and

	(b) under Patent Claims of such Contributor to make, use, sell, offer
	    for sale, have made, import, and otherwise transfer either its
	    Contributions or its Contributor Version.

	2.2. Effective Date

	The licenses granted in Section 2.1 with respect to any Contribution
	become effective for each Contribution on the date the Contributor first
	distributes such Contribution.

	2.3. Limitations on Grant Scope

	The licenses granted in this Section 2 are the only rights granted under
	this License. No additional rights or licenses will be implied from the
	distribution or licensing of Covered Software under this License.
	Notwithstanding Section 2.1(b) above, no patent license is granted by a
	Contributor:

	(a) for any code that a Contributor has removed from Covered Software;
	    or

	(b) for infringements caused by: (i) Your and any other third party's
	    modifications of Covered Software, or (ii) the combination of its
	    Contributions with other software (except as part of its Contributor
	    Version); or

	(c) under Patent Claims infringed by Covered Software in the absence of
	    its Contributions.

	This License does not grant any rights in the trademarks, service marks,
	or logos of any Contributor (except as may be necessary to comply with
	the notice requirements in Section 3.4).

	2.4. Subsequent Licenses

	No Contributor makes additional grants as a result of Your choice to
	distribute the Covered Software under a subsequent version of this
	License (see Section 10.2) or under the terms of a Secondary License (if
	permitted under the terms of Section 3.3).

	2.5. Representation

	Each Contributor represents that the Contributor believes its
	Contributions are its original creation(s) or it has sufficient rights
	to grant the rights to its Contributions conveyed by this License.

	2.6. Fair Use

	This License is not intended to limit any rights You have under
	applicable copyright doctrines of fair use, fair dealing, or other
	equivalents.

	2.7. Conditions

	Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
	in Section 2.1.

	3. Responsibilities
	-------------------

	3.1. Distribution of Source Form

	All distribution of Covered Software in Source Code Form, including any
	Modifications that You create or to which You contribute, must be under
	the terms of this License. You must inform recipients that the Source
	Code Form of the Covered Software is governed by the terms of this
	License, and how they can obtain a copy of this License. You may not
	attempt to alter or restrict the recipients' rights in the Source Code
	Form.

	3.2. Distribution of Executable Form

	If You distribute Covered Software in Executable Form then:

	(a) such Covered Software must also be made available in Source Code
	    Form, as described in Section 3.1, and You must inform recipients of
	    the Executable Form how they can obtain a copy of such Source Code
	    Form by reasonable means in a timely manner, at a charge no more
	    than the cost of distribution to the recipient; and

	(b) You may distribute such Executable Form under the terms of this
	    License, or sublicense it under different terms, provided that the
	    license for the Executable Form does not attempt to limit or alter
	    the recipients' rights in the Source Code Form under this License.

	3.3. Distribution of a Larger Work

	You may create and distribute a Larger Work under terms of Your choice,
	provided that You also comply with the requirements of this License for
	the Covered Software. If the Larger Work is a combination of Covered
	Software with a work governed by one or more Secondary Licenses, and the
	Covered Software is not Incompatible With Secondary Licenses, this
	License permits You to additionally distribute such Covered Software
	under the terms of such Secondary License(s), so that the recipient of
	the Larger Work may, at their option, further distribute the Covered
	Software under the terms of either this License or such Secondary
	License(s).

	3.4. Notices

	You may not remove or alter the substance of any license notices
	(including copyright notices, patent notices, disclaimers of warranty,
	or limitations of liability) contained within the Source Code Form of
	the Covered Software, except that You may alter any license notices to
	the extent required to remedy known factual inaccuracies.

	3.5. Application of Additional Terms

	You may choose to offer, and to charge a fee for, warranty, support,
	indemnity or liability obligations to one or more recipients of Covered
	Software. However, You may do so only on Your own behalf, and not on
	behalf of any Contributor. You must make it absolutely clear that any
	such warranty, support, indemnity, or liability obligation is offered by
	You alone, and You hereby agree to indemnify every Contributor for any
	liability incurred by such Contributor as a result of warranty, support,
	indemnity or liability terms You offer. You may include additional
	disclaimers of warranty and limitations of liability specific to any
	jurisdiction.

	4. Inability to Comply Due to Statute or Regulation
	---------------------------------------------------

	If it is impossible for You to comply with any of the terms of this
	License with respect to some or all of the Covered Software due to
	statute, judicial order, or regulation then You must: (a) comply with
	the terms of this License to the maximum extent possible; and (b)
	describe the limitations and the code they affect. Such description must
	be placed in a text file included with all distributions of the Covered
	Software under this License. Except to the extent prohibited by statute
	or regulation, such description must be sufficiently detailed for a
	recipient of ordinary skill to be able to understand it.

	5. Termination
	--------------

	5.1. The rights granted under this License will terminate automatically
	if You fail to comply with any of its terms. However, if You become
	compliant, then the rights granted under this License from a particular
	Contributor are reinstated (a) provisionally, unless and until such
	Contributor explicitly and finally terminates Your grants, and (b) on an
	ongoing basis, if such Contributor fails to notify You of the
	non-compliance by some reasonable means prior to 60 days after You have
	come back into compliance. Moreover, Your grants from a particular
	Contributor are reinstated on an ongoing basis if such Contributor
	notifies You of the non-compliance by some reasonable means, this is the
	first time You have received notice of non-compliance with this License
	from such Contributor, and You become compliant prior to 30 days after
	Your receipt of the notice.

	5.2. If You initiate litigation against any entity by asserting a patent
	infringement claim (excluding declaratory judgment actions,
	counter-claims, and cross-claims) alleging that a Contributor Version
	directly or indirectly infringes any patent, then the rights granted to
	You by any and all Contributors for the Covered Software under Section
	2.1 of this License shall terminate.

	5.3. In the event of termination under Sections 5.1 or 5.2 above, all
	end user license agreements (excluding distributors and resellers) which
	have been validly granted by You or Your distributors under this License
	prior to termination shall survive termination.

	*  statutory, including, without limitation, warranties that the       *
	*  Covered Software is free of defects, merchantable, fit for a        *
	*  particular purpose or non-infringing. The entire risk as to the     *
	*  quality and performance of the Covered Software is with You.        *
	*  Should any Covered Software prove defective in any respect, You     *
	*  (not any Contributor) assume the cost of any necessary servicing,   *
	*  repair, or correction. This disclaimer of warranty constitutes an   *
	*  essential part of this License. No use of any Covered Software is   *
	*  authorized under this License except under this disclaimer.         *
	*                                                                      *

	*  including, without limitation, damages for lost profits, loss of    *

	*  jurisdictions do not allow the exclusion or limitation of           *

	************************************************************************

	8. Litigation
	-------------

	Any litigation relating to this License may be brought only in the
	courts of a jurisdiction where the defendant maintains its principal
	place of business and such litigation shall be governed by laws of that
	jurisdiction, without reference to its conflict-of-law provisions.
	Nothing in this Section shall prevent a party's ability to bring
	cross-claims or counter-claims.

	9. Miscellaneous
	----------------

	This License represents the complete agreement concerning the subject
	matter hereof. If any provision of this License is held to be
	unenforceable, such provision shall be reformed only to the extent
	necessary to make it enforceable. Any law or regulation which provides
	that the language of a contract shall be construed against the drafter
	shall not be used to construe this License against a Contributor.

	10. Versions of the License
	---------------------------

	10.1. New Versions

	Mozilla Foundation is the license steward. Except as provided in Section
	10.3, no one other than the license steward has the right to modify or
	publish new versions of this License. Each version will be given a
	distinguishing version number.

	10.2. Effect of New Versions

	You may distribute the Covered Software under the terms of the version
	of the License under which You originally received the Covered Software,
	or under the terms of any subsequent version published by the license

	10.3. Modified Versions

	If you create software not governed by this License, and you want to
	create a new license for such software, you may create and use a
	modified version of this License if you rename the license and remove
	any references to the name of the license steward (except to note that
	such modified license differs from this License).

	10.4. Distributing Source Code Form that is Incompatible With Secondary
	Licenses

	If You choose to distribute Source Code Form that is Incompatible With
	Secondary Licenses under the terms of this version of the License, the
