 and that Source Code form must be distributed only under the terms of
 this License. You must include a copy of this License with every copy
 of the Source Code form of the Covered Software You distribute or
 otherwise make available. You must inform recipients of any such
 Covered Software in Executable form as to how they can obtain such
 Covered Software in Source Code form in a reasonable manner on or
 through a medium customarily used for software exchange.
 .
 3.2. Modifications.
 .
 The Modifications that You create or to which You contribute are
 governed by the terms of this License. You represent that You believe
 Your Modifications are Your original creation(s) and/or You have
 sufficient rights to grant the rights conveyed by this License.
 .
 3.3. Required Notices.
 .
 You must include a notice in each of Your Modifications that
 identifies You as the Contributor of the Modification.  You may not
 remove or alter any copyright, patent or trademark notices contained
 within the Covered Software, or any notices of licensing or any
 descriptive text giving attribution to any Contributor or the Initial
 Developer.
 .
 3.4. Application of Additional Terms.
 .
 You may not offer or impose any terms on any Covered Software in
 Source Code form that alters or restricts the applicable version of
 this License or the recipients’ rights hereunder. 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
 the Initial Developer or 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 the Initial Developer and every Contributor for any
 liability incurred by the Initial Developer or such Contributor as a
 result of warranty, support, indemnity or liability terms You offer.
 .
 3.5. Distribution of Executable Versions.
 .
 You may distribute the Executable form of the Covered Software under
 the terms of this License or under the terms of a license of Your
 choice, which may contain terms different from this License, provided
 that You are in compliance with the terms of this License and that
 the license for the Executable form does not attempt to limit or
 alter the recipient’s rights in the Source Code form from the rights
 set forth in this License. If You distribute the Covered Software in
 Executable form under a different license, You must make it
 absolutely clear that any terms which differ from this License are
 offered by You alone, not by the Initial Developer or
 Contributor. You hereby agree to indemnify the Initial Developer and
 every Contributor for any liability incurred by the Initial Developer
 or such Contributor as a result of any such terms You offer.
 .
 3.6. Larger Works.
 .
 You may create a Larger Work by combining Covered Software with other
 code not governed by the terms of this License and distribute the
 Larger Work as a single product. In such a case, You must make sure
 the requirements of this License are fulfilled for the Covered
 Software.
 .
 Versions of the License.
 .
 4.1. New Versions.
 .
 Sun Microsystems, Inc. is the initial license steward and may publish
 revised and/or new versions of this License from time to time. Each
 version will be given a distinguishing version number. Except as
 provided in Section 4.3, no one other than the license steward has
 the right to modify this License.
 .
 4.2. Effect of New Versions.
 .
 You may always continue to use, distribute or otherwise make the
 Covered Software available under the terms of the version of the
 License under which You originally received the Covered Software. If
 the Initial Developer includes a notice in the Original Software
 prohibiting it from being distributed or otherwise made available
 under any subsequent version of the License, You must distribute and
 make the Covered Software available under the terms of the version of
 the License under which You originally received the Covered
 Software. Otherwise, You may also choose to use, distribute or
 otherwise make the Covered Software available under the terms of any
 subsequent version of the License published by the license steward.
 .
 4.3. Modified Versions.
 .
 When You are an Initial Developer and You want to create a new
 license for Your Original Software, You may create and use a modified
 version of this License if You: (a) rename the license and remove any
 references to the name of the license steward (except to note that
 the license differs from this License); and (b) otherwise make it
 clear that the license contains terms which differ from this License.
 .
 5. DISCLAIMER OF WARRANTY.
 .
 COVERED SOFTWARE IS PROVIDED UNDER THIS LICENSE ON AN “AS IS” BASIS,
 WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, 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 THE INITIAL DEVELOPER OR ANY OTHER
 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
 HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
 .
 6. TERMINATION.
 .
 6.1. This License and the rights granted hereunder will terminate
 automatically if You fail to comply with terms herein and fail to
 cure such breach within 30 days of becoming aware of the
 breach. Provisions which, by their nature, must remain in effect
 beyond the termination of this License shall survive.
 .
 6.2. If You assert a patent infringement claim (excluding declaratory
 judgment actions) against Initial Developer or a Contributor (the
 Initial Developer or Contributor against whom You assert such claim
 is referred to as “Participant”) alleging that the Participant
 Software (meaning the Contributor Version where the Participant is a
 Contributor or the Original Software where the Participant is the
 Initial Developer) directly or indirectly infringes any patent, then
 any and all rights granted directly or indirectly to You by such
 Participant, the Initial Developer (if the Initial Developer is not
 the Participant) and all Contributors under Sections 2.1 and/or 2.2
 of this License shall, upon 60 days notice from Participant terminate
 prospectively and automatically at the expiration of such 60 day
 notice period, unless if within such 60 day period You withdraw Your
 claim with respect to the Participant Software against such
 Participant either unilaterally or pursuant to a written agreement
 with Participant.
 .
 6.3. If You assert a patent infringement claim against Participant
 alleging that the Participant Software directly or indirectly
 infringes any patent where such claim is resolved (such as by license
 or settlement) prior to the initiation of patent infringement
 litigation, then the reasonable value of the licenses granted by such
 Participant under Sections 2.1 or 2.2 shall be taken into account in
 determining the amount or value of any payment or license.
 .
 6.4. In the event of termination under Sections 6.1 or 6.2 above, all
 end user licenses that have been validly granted by You or any
 distributor hereunder prior to termination (excluding licenses
 granted to You by any distributor) shall survive termination.
 .
 7. LIMITATION OF LIABILITY.
 .
 UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
 (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE
 INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF
 COVERED SOFTWARE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE
 TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL
 DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR
 LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR
 ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY
 SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS
 LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR
 PERSONAL INJURY RESULTING FROM SUCH PARTY’S NEGLIGENCE TO THE EXTENT
 APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT
 ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL
 DAMAGES, SO THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
 .
 8. U.S. GOVERNMENT END USERS.
 .
 The Covered Software is a “commercial item,” as that term is defined
 in 48 C.F.R. 2.101 (Oct. 1995), consisting of “commercial computer
 software” (as that term is defined at 48 C.F.R. § 252.227-7014(a)(1))
 and “commercial computer software documentation” as such terms are
 used in 48 C.F.R. 12.212 Sept. 1995). Consistent with 48
 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June
 1995), all U.S. Government End Users acquire Covered Software with
 only those rights set forth herein. This U.S. Government Rights
 clause is in lieu of, and supersedes, any other FAR, DFAR, or other
 clause or provision that addresses Government rights in computer
 software under this License.
 .
 9. MISCELLANEOUS.
 .
 This License represents the complete agreement concerning 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. This License shall be governed by
 the law of the jurisdiction specified in a notice contained within
 the Original Software (except to the extent applicable law, if any,
 provides otherwise), excluding such jurisdiction’s conflict-of-law
 provisions. Any litigation relating to this License shall be subject
 to the jurisdiction of the courts located in the jurisdiction and
 venue specified in a notice contained within the Original Software,
 with the losing party responsible for costs, including, without
 limitation, court costs and reasonable attorneys’ fees and
 expenses. The application of the United Nations Convention on
 Contracts for the International Sale of Goods is expressly
 excluded. Any law or regulation which provides that the language of a
 contract shall be construed against the drafter shall not apply to
 this License. You agree that You alone are responsible for compliance
 with the United States export administration regulations (and the
 export control laws and regulation of any other countries) when You
 use, distribute or otherwise make available any Covered Software.
 .
 10. RESPONSIBILITY FOR CLAIMS.
 .
 As between Initial Developer and the Contributors, each party is
 responsible for claims and damages arising, directly or indirectly,
 out of its utilization of rights under this License and You agree to
 work with Initial Developer and Contributors to distribute such
 responsibility on an equitable basis. Nothing herein is intended or
 shall be deemed to constitute any admission of liability.
 .
 NOTICE PURSUANT TO SECTION 9 OF THE COMMON DEVELOPMENT AND
 DISTRIBUTION LICENSE (CDDL)
 .
 The OpenSolaris code released under the CDDL shall be governed by the
 laws of the State of California (excluding conflict-of-law
 provisions). Any litigation relating to this License shall be subject
 to the jurisdiction of the Federal Courts of the Northern District of
 California and the state courts of the State of California, with
 venue lying in Santa Clara County, California.

               in part; and
 .
            b. produce, reproduce, and Share Adapted Material.
 .
       2. Exceptions and Limitations. For the avoidance of doubt, where
          Exceptions and Limitations apply to Your use, this Public
          License does not apply, and You do not need to comply with
          its terms and conditions.
 .
       3. Term. The term of this Public License is specified in Section
          6(a).
 .
       4. Media and formats; technical modifications allowed. The
          Licensor authorizes You to exercise the Licensed Rights in
          all media and formats whether now known or hereafter created,
          and to make technical modifications necessary to do so. The
          Licensor waives and/or agrees not to assert any right or
          authority to forbid You from making technical modifications
          necessary to exercise the Licensed Rights, including
          technical modifications necessary to circumvent Effective
          Technological Measures. For purposes of this Public License,
          simply making modifications authorized by this Section 2(a)
          (4) never produces Adapted Material.
 .
       5. Downstream recipients.
 .
            a. Offer from the Licensor -- Licensed Material. Every
               recipient of the Licensed Material automatically
               receives an offer from the Licensor to exercise the
               Licensed Rights under the terms and conditions of this
               Public License.
 .
            b. No downstream restrictions. You may not offer or impose
               any additional or different terms or conditions on, or
               apply any Effective Technological Measures to, the
               Licensed Material if doing so restricts exercise of the
               Licensed Rights by any recipient of the Licensed
               Material.
 .
       6. No endorsement. Nothing in this Public License constitutes or
          may be construed as permission to assert or imply that You
          are, or that Your use of the Licensed Material is, connected
          with, or sponsored, endorsed, or granted official status by,
          the Licensor or others designated to receive attribution as
          provided in Section 3(a)(1)(A)(i).
 .
  b. Other rights.
 .
       1. Moral rights, such as the right of integrity, are not
          licensed under this Public License, nor are publicity,
          privacy, and/or other similar personality rights; however, to
          the extent possible, the Licensor waives and/or agrees not to
          assert any such rights held by the Licensor to the limited
          extent necessary to allow You to exercise the Licensed
          Rights, but not otherwise.
 .
       2. Patent and trademark rights are not licensed under this
          Public License.
 .
       3. To the extent possible, the Licensor waives any right to
          collect royalties from You for the exercise of the Licensed
          Rights, whether directly or through a collecting society
          under any voluntary or waivable statutory or compulsory
          licensing scheme. In all other cases the Licensor expressly
          reserves any right to collect such royalties.
 .
 Section 3 -- License Conditions.
 .
 Your exercise of the Licensed Rights is expressly made subject to the
 following conditions.
 .
  a. Attribution.
 .
       1. If You Share the Licensed Material (including in modified
          form), You must:
 .
            a. retain the following if it is supplied by the Licensor
               with the Licensed Material:
 .
                 i. identification of the creator(s) of the Licensed
                    Material and any others designated to receive
                    attribution, in any reasonable manner requested by
                    the Licensor (including by pseudonym if
                    designated);
 .
                ii. a copyright notice;
 .
               iii. a notice that refers to this Public License;
 .
                iv. a notice that refers to the disclaimer of
                    warranties;
 .
                 v. a URI or hyperlink to the Licensed Material to the
                    extent reasonably practicable;
 .
            b. indicate if You modified the Licensed Material and
               retain an indication of any previous modifications; and
 .
            c. indicate the Licensed Material is licensed under this
               Public License, and include the text of, or the URI or
               hyperlink to, this Public License.
 .
       2. You may satisfy the conditions in Section 3(a)(1) in any
          reasonable manner based on the medium, means, and context in
          which You Share the Licensed Material. For example, it may be
          reasonable to satisfy the conditions by providing a URI or
          hyperlink to a resource that includes the required
          information.
 .
       3. If requested by the Licensor, You must remove any of the
          information required by Section 3(a)(1)(A) to the extent
          reasonably practicable.
 .
       4. If You Share Adapted Material You produce, the Adapter's
          License You apply must not prevent recipients of the Adapted
          Material from complying with this Public License.
 .
 Section 4 -- Sui Generis Database Rights.
 .
 Where the Licensed Rights include Sui Generis Database Rights that
 apply to Your use of the Licensed Material:
 .
  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
     to extract, reuse, reproduce, and Share all or a substantial
     portion of the contents of the database;
 .
  b. if You include all or a substantial portion of the database
     contents in a database in which You have Sui Generis Database
     Rights, then the database in which You have Sui Generis Database
     Rights (but not its individual contents) is Adapted Material; and
 .
  c. You must comply with the conditions in Section 3(a) if You Share
     all or a substantial portion of the contents of the database.
 .
 For the avoidance of doubt, this Section 4 supplements and does not
 replace Your obligations under this Public License where the Licensed
 Rights include other Copyright and Similar Rights.
 .
 Section 5 -- Disclaimer of Warranties and Limitation of Liability.
 .
  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
 .
  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
 .
  c. The disclaimer of warranties and limitation of liability provided
     above shall be interpreted in a manner that, to the extent
     possible, most closely approximates an absolute disclaimer and
     waiver of all liability.
 .
 Section 6 -- Term and Termination.
 .
  a. This Public License applies for the term of the Copyright and
     Similar Rights licensed here. However, if You fail to comply with
     this Public License, then Your rights under this Public License
     terminate automatically.
 .
  b. Where Your right to use the Licensed Material has terminated under
     Section 6(a), it reinstates:
 .
       1. automatically as of the date the violation is cured, provided
          it is cured within 30 days of Your discovery of the
          violation; or
 .
       2. upon express reinstatement by the Licensor.
 .
     For the avoidance of doubt, this Section 6(b) does not affect any
     right the Licensor may have to seek remedies for Your violations
     of this Public License.
 .
  c. For the avoidance of doubt, the Licensor may also offer the
     Licensed Material under separate terms or conditions or stop
     distributing the Licensed Material at any time; however, doing so
     will not terminate this Public License.
 .
  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
     License.
 .
 Section 7 -- Other Terms and Conditions.
 .
  a. The Licensor shall not be bound by any additional or different
     terms or conditions communicated by You unless expressly agreed.
 .
  b. Any arrangements, understandings, or agreements regarding the
     Licensed Material not stated herein are separate from and
     independent of the terms and conditions of this Public License.
 .
 Section 8 -- Interpretation.
 .
  a. For the avoidance of doubt, this Public License does not, and
     shall not be interpreted to, reduce, limit, restrict, or impose
     conditions on any use of the Licensed Material that could lawfully
     be made without permission under this Public License.
 .
  b. To the extent possible, if any provision of this Public License is
     deemed unenforceable, it shall be automatically reformed to the
     minimum extent necessary to make it enforceable. If the provision
     cannot be reformed, it shall be severed from this Public License
     without affecting the enforceability of the remaining terms and
     conditions.
 .
  c. No term or condition of this Public License will be waived and no
     failure to comply consented to unless expressly agreed to by the
     Licensor.
 .
  d. Nothing in this Public License constitutes or may be interpreted
     as a limitation upon, or waiver of, any privileges and immunities
     that apply to the Licensor or You, including from the legal
     processes of any jurisdiction or authority.
