-CERN Open Hardware Licence Version 2 - Strongly Reciprocal
-
-
-Preamble
-
-CERN has developed this licence to promote collaboration among
-hardware designers and to provide a legal tool which supports the
-freedom to use, study, modify, share and distribute hardware designs
-and products based on those designs. Version 2 of the CERN Open
-Hardware Licence comes in three variants: CERN-OHL-P (permissive); and
-two reciprocal licences: CERN-OHL-W (weakly reciprocal) and this
-licence, CERN-OHL-S (strongly reciprocal).
-
-The CERN-OHL-S is copyright CERN 2020. Anyone is welcome to use it, in
-unmodified form only.
-
-Use of this Licence does not imply any endorsement by CERN of any
-Licensor or their designs nor does it imply any involvement by CERN in
-their development.
-
-
-1 Definitions
-
-  1.1 'Licence' means this CERN-OHL-S.
-
-  1.2 'Compatible Licence' means
-
-       a) any earlier version of the CERN Open Hardware licence, or
-
-       b) any version of the CERN-OHL-S, or
-
-       c) any licence which permits You to treat the Source to which
-          it applies as licensed under CERN-OHL-S provided that on
-          Conveyance of any such Source, or any associated Product You
-          treat the Source in question as being licensed under
-          CERN-OHL-S.
-
-  1.3 'Source' means information such as design materials or digital
-      code which can be applied to Make or test a Product or to
-      prepare a Product for use, Conveyance or sale, regardless of its
-      medium or how it is expressed. It may include Notices.
-
-  1.4 'Covered Source' means Source that is explicitly made available
-      under this Licence.
-
-  1.5 'Product' means any device, component, work or physical object,
-      whether in finished or intermediate form, arising from the use,
-      application or processing of Covered Source.
-
-  1.6 'Make' means to create or configure something, whether by
-      manufacture, assembly, compiling, loading or applying Covered
-      Source or another Product or otherwise.
-
-  1.7 'Available Component' means any part, sub-assembly, library or
-      code which:
-
-       a) is licensed to You as Complete Source under a Compatible
-          Licence; or
-
-       b) is available, at the time a Product or the Source containing
-          it is first Conveyed, to You and any other prospective
-          licensees
-
-            i) as a physical part with sufficient rights and
-               information (including any configuration and
-               programming files and information about its
-               characteristics and interfaces) to enable it either to
-               be Made itself, or to be sourced and used to Make the
-               Product; or
-           ii) as part of the normal distribution of a tool used to
-               design or Make the Product.
-
-  1.8 'Complete Source' means the set of all Source necessary to Make
-      a Product, in the preferred form for making modifications,
-      including necessary installation and interfacing information
-      both for the Product, and for any included Available Components.
-      If the format is proprietary, it must also be made available in
-      a format (if the proprietary tool can create it) which is
-      viewable with a tool available to potential licensees and
-      licensed under a licence approved by the Free Software
-      Foundation or the Open Source Initiative. Complete Source need
-      not include the Source of any Available Component, provided that
-      You include in the Complete Source sufficient information to
-      enable a recipient to Make or source and use the Available
-      Component to Make the Product.
-
-  1.9 'Source Location' means a location where a Licensor has placed

-
-
-2 Applicability
-
-  2.1 This Licence governs the use, copying, modification, Conveying
-      of Covered Source and Products, and the Making of Products. By
-      exercising any right granted under this Licence, You irrevocably
-      accept these terms and conditions.
-
-  2.2 This Licence is granted by the Licensor directly to You, and
-      shall apply worldwide and without limitation in time.
-
-  2.3 You shall not attempt to restrict by contract or otherwise the
-      rights granted under this Licence to other Licensees.
-
-  2.4 This Licence is not intended to restrict fair use, fair dealing,
-      or any other similar right.
-
-
-3 Copying, Modifying and Conveying Covered Source
-
-  3.1 You may copy and Convey verbatim copies of Covered Source, in
-      any medium, provided You retain all Notices.
-
-  3.2 You may modify Covered Source, other than Notices, provided that
-      You irrevocably undertake to make that modified Covered Source
-      available from a Source Location should You Convey a Product in
-      circumstances where the recipient does not otherwise receive a
-      copy of the modified Covered Source. In each case subsection 3.3
-      shall apply.
-
-      You may only delete Notices if they are no longer applicable to
-      the corresponding Covered Source as modified by You and You may
-      add additional Notices applicable to Your modifications.
-      Including Covered Source in a larger work is modifying the
-      Covered Source, and the larger work becomes modified Covered
-      Source.
-
-  3.3 You may Convey modified Covered Source (with the effect that You
-      shall also become a Licensor) provided that You:
-
-       a) retain Notices as required in subsection 3.2;
-
-       b) add a Notice to the modified Covered Source stating that You
-          have modified it, with the date and brief description of how
-          You have modified it;
-
-       c) add a Source Location Notice for the modified Covered Source
-          if You Convey in circumstances where the recipient does not
-          otherwise receive a copy of the modified Covered Source; and
-
-       d) license the modified Covered Source under the terms and
-          conditions of this Licence (or, as set out in subsection
-          8.3, a later version, if permitted by the licence of the
-          original Covered Source). Such modified Covered Source must
-          be licensed as a whole, but excluding Available Components
-          contained in it, which remain licensed under their own
-          applicable licences.
-
-
-4 Making and Conveying Products
-
-You may Make Products, and/or Convey them, provided that You either
-provide each recipient with a copy of the Complete Source or ensure
-that each recipient is notified of the Source Location of the Complete
-Source. That Complete Source is Covered Source, and You must
-accordingly satisfy Your obligations set out in subsection 3.3. If
-specified in a Notice, the Product must visibly and securely display
-the Source Location on it or its packaging or documentation in the
-manner specified in that Notice.
-
-
-5 Research and Development
-
-You may Convey Covered Source, modified Covered Source or Products to
-a legal entity carrying out development, testing or quality assurance
-work on Your behalf provided that the work is performed on terms which
-prevent the entity from both using the Source or Products for its own
-internal purposes and Conveying the Source or Products or any
-modifications to them to any person other than You. Any modifications
-made by the entity shall be deemed to be made by You pursuant to
-subsection 3.2.
-
-
-6 DISCLAIMER AND LIABILITY
-
-  6.1 DISCLAIMER OF WARRANTY -- The Covered Source and any Products
-      are provided 'as is' and any express or implied warranties,
-      including, but not limited to, implied warranties of
-      merchantability, of satisfactory quality, non-infringement of
-      third party rights, and fitness for a particular purpose or use
-      are disclaimed in respect of any Source or Product to the
-      maximum extent permitted by law. The Licensor makes no
-      representation that any Source or Product does not or will not
-      infringe any patent, copyright, trade secret or other
-      proprietary right. The entire risk as to the use, quality, and
-      performance of any Source or Product shall be with You and not
-      the Licensor. This disclaimer of warranty is an essential part
-      of this Licence and a condition for the grant of any rights
-      granted under this Licence.
-
-  6.2 EXCLUSION AND LIMITATION OF LIABILITY -- The Licensor shall, to
-      the maximum extent permitted by law, have no liability for
-      direct, indirect, special, incidental, consequential, exemplary,
-      punitive or other damages of any character including, without
-      limitation, procurement of substitute goods or services, loss of
-      use, data or profits, or business interruption, however caused
-      and on any theory of contract, warranty, tort (including
-      negligence), product liability or otherwise, arising in any way
-      in relation to the Covered Source, modified Covered Source
-      and/or the Making or Conveyance of a Product, even if advised of
-      the possibility of such damages, and You shall hold the
-      Licensor(s) free and harmless from any liability, costs,
-      damages, fees and expenses, including claims by third parties,
-      in relation to such use.
-
-
-7 Patents
-
-  7.1 Subject to the terms and conditions of this Licence, each
-      Licensor hereby grants to You a perpetual, worldwide,
-      non-exclusive, no-charge, royalty-free, irrevocable (except as
-      stated in subsections 7.2 and 8.4) patent licence to Make, have
-      Made, use, offer to sell, sell, import, and otherwise transfer
-      the Covered Source and Products, where such licence applies only
-      to those patent claims licensable by such Licensor that are
-      necessarily infringed by exercising rights under the Covered
-      Source as Conveyed by that Licensor.
-
-  7.2 If You institute patent litigation against any entity (including
-      a cross-claim or counterclaim in a lawsuit) alleging that the
-      Covered Source or a Product constitutes direct or contributory
-      patent infringement, or You seek any declaration that a patent
-      licensed to You under this Licence is invalid or unenforceable
-      then any rights granted to You under this Licence shall
-      terminate as of the date such process is initiated.
-
-
-8 General
-
-  8.1 If any provisions of this Licence are or subsequently become
-      invalid or unenforceable for any reason, the remaining
-      provisions shall remain effective.
-
-  8.2 You shall not use any of the name (including acronyms and
-      abbreviations), image, or logo by which the Licensor or CERN is
-      known, except where needed to comply with section 3, or where
-      the use is otherwise allowed by law. Any such permitted use
-      shall be factual and shall not be made so as to suggest any kind
-      of endorsement or implication of involvement by the Licensor or
-      its personnel.
-
-  8.3 CERN may publish updated versions and variants of this Licence
-      which it considers to be in the spirit of this version, but may
-      differ in detail to address new problems or concerns. New
-      versions will be published with a unique version number and a
-      variant identifier specifying the variant. If the Licensor has
-      specified that a given variant applies to the Covered Source
-      without specifying a version, You may treat that Covered Source
-      as being released under any version of the CERN-OHL with that
-      variant. If no variant is specified, the Covered Source shall be
-      treated as being released under CERN-OHL-S. The Licensor may
-      also specify that the Covered Source is subject to a specific
-      version of the CERN-OHL or any later version in which case You
-      may apply this or any later version of CERN-OHL with the same
-      variant identifier published by CERN.
-
-  8.4 This Licence shall terminate with immediate effect if You fail
-      to comply with any of its terms and conditions.
-
-  8.5 However, if You cease all breaches of this Licence, then Your
-      Licence from any Licensor is reinstated unless such Licensor has
-      terminated this Licence by giving You, while You remain in
-      breach, a notice specifying the breach and requiring You to cure
-      it within 30 days, and You have failed to come into compliance
-      in all material respects by the end of the 30 day period. Should
-      You repeat the breach after receipt of a cure notice and
-      subsequent reinstatement, this Licence will terminate
-      immediately and permanently. Section 6 shall continue to apply
-      after any termination.
-
-  8.6 This Licence shall not be enforceable except by a Licensor
-      acting as such, and third party beneficiary rights are
-      specifically excluded.

+
+Creative Commons public licenses provide a standard set of terms and

+exhaustive, and do not form part of our licenses.
+
+     Considerations for licensors: Our public licenses are
+     intended for use by those authorized to give the public
+     permission to use material in ways otherwise restricted by
+     copyright and certain other rights. Our licenses are
+     irrevocable. Licensors should read and understand the terms
+     and conditions of the license they choose before applying it.
+     Licensors should also secure all rights necessary before
+     applying our licenses so that the public can reuse the
+     material as expected. Licensors should clearly mark any
+     material not subject to the license. This includes other CC-

+
+     Considerations for the public: By using one of our public

+     such as asking that all changes be marked or described.
+     Although not required by our licenses, you are encouraged to
+     respect those requests where reasonable. More considerations

+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               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. Additional offer from the Licensor -- Adapted Material.
+               Every recipient of Adapted Material from You
+               automatically receives an offer from the Licensor to
+               exercise the Licensed Rights in the Adapted Material
+               under the conditions of the Adapter's License You apply.
+
+            c. 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.
+
+  b. ShareAlike.
+
+     In addition to the conditions in Section 3(a), if You Share
+     Adapted Material You produce, the following conditions also apply.
+
+       1. The Adapter's License You apply must be a Creative Commons
+          license with the same License Elements, this version or
+          later, or a BY-SA Compatible License.
+
+       2. You must include the text of, or the URI or hyperlink to, the
+          Adapter's License You apply. You may satisfy this condition
+          in any reasonable manner based on the medium, means, and
+          context in which You Share Adapted Material.
+
+       3. You may not offer or impose any additional or different terms
+          or conditions on, or apply any Effective Technological
+          Measures to, Adapted Material that restrict exercise of the
+          rights granted under the Adapter's License You apply.
+
+
+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,
+     including for purposes of Section 3(b); 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.

+CERN Open Hardware Licence Version 2 - Strongly Reciprocal
+
+
+Preamble
+
+CERN has developed this licence to promote collaboration among
+hardware designers and to provide a legal tool which supports the
+freedom to use, study, modify, share and distribute hardware designs
+and products based on those designs. Version 2 of the CERN Open
+Hardware Licence comes in three variants: CERN-OHL-P (permissive); and
+two reciprocal licences: CERN-OHL-W (weakly reciprocal) and this
+licence, CERN-OHL-S (strongly reciprocal).
+
+The CERN-OHL-S is copyright CERN 2020. Anyone is welcome to use it, in
+unmodified form only.
+
+Use of this Licence does not imply any endorsement by CERN of any
+Licensor or their designs nor does it imply any involvement by CERN in
+their development.
+
+
+1 Definitions
+
+  1.1 'Licence' means this CERN-OHL-S.
+
+  1.2 'Compatible Licence' means
+
+       a) any earlier version of the CERN Open Hardware licence, or
+
+       b) any version of the CERN-OHL-S, or
+
+       c) any licence which permits You to treat the Source to which
+          it applies as licensed under CERN-OHL-S provided that on
+          Conveyance of any such Source, or any associated Product You
+          treat the Source in question as being licensed under
+          CERN-OHL-S.
+
+  1.3 'Source' means information such as design materials or digital
+      code which can be applied to Make or test a Product or to
+      prepare a Product for use, Conveyance or sale, regardless of its
+      medium or how it is expressed. It may include Notices.
+
+  1.4 'Covered Source' means Source that is explicitly made available
+      under this Licence.
+
+  1.5 'Product' means any device, component, work or physical object,
+      whether in finished or intermediate form, arising from the use,
+      application or processing of Covered Source.
+
+  1.6 'Make' means to create or configure something, whether by
+      manufacture, assembly, compiling, loading or applying Covered
+      Source or another Product or otherwise.
+
+  1.7 'Available Component' means any part, sub-assembly, library or
+      code which:
+
+       a) is licensed to You as Complete Source under a Compatible
+          Licence; or
+
+       b) is available, at the time a Product or the Source containing
+          it is first Conveyed, to You and any other prospective
+          licensees
+
+            i) as a physical part with sufficient rights and
+               information (including any configuration and
+               programming files and information about its
+               characteristics and interfaces) to enable it either to
+               be Made itself, or to be sourced and used to Make the
+               Product; or
+           ii) as part of the normal distribution of a tool used to
+               design or Make the Product.
+
+  1.8 'Complete Source' means the set of all Source necessary to Make
+      a Product, in the preferred form for making modifications,
+      including necessary installation and interfacing information
+      both for the Product, and for any included Available Components.
+      If the format is proprietary, it must also be made available in
+      a format (if the proprietary tool can create it) which is
+      viewable with a tool available to potential licensees and
+      licensed under a licence approved by the Free Software
+      Foundation or the Open Source Initiative. Complete Source need
+      not include the Source of any Available Component, provided that
+      You include in the Complete Source sufficient information to
+      enable a recipient to Make or source and use the Available
+      Component to Make the Product.
+
+  1.9 'Source Location' means a location where a Licensor has placed
+      Covered Source, and which that Licensor reasonably believes will
+      remain easily accessible for at least three years for anyone to
+      obtain a digital copy.
+
+ 1.10 'Notice' means copyright, acknowledgement and trademark notices,
+      Source Location references, modification notices (subsection
+      3.3(b)) and all notices that refer to this Licence and to the
+      disclaimer of warranties that are included in the Covered
+      Source.
+
+ 1.11 'Licensee' or 'You' means any person exercising rights under
+      this Licence.
+
+ 1.12 'Licensor' means a natural or legal person who creates or
+      modifies Covered Source. A person may be a Licensee and a
+      Licensor at the same time.
+
+ 1.13 'Convey' means to communicate to the public or distribute.
+
+
+2 Applicability
+
+  2.1 This Licence governs the use, copying, modification, Conveying
+      of Covered Source and Products, and the Making of Products. By
+      exercising any right granted under this Licence, You irrevocably
+      accept these terms and conditions.
+
+  2.2 This Licence is granted by the Licensor directly to You, and
+      shall apply worldwide and without limitation in time.
+
+  2.3 You shall not attempt to restrict by contract or otherwise the
+      rights granted under this Licence to other Licensees.
+
+  2.4 This Licence is not intended to restrict fair use, fair dealing,
+      or any other similar right.
+
+
+3 Copying, Modifying and Conveying Covered Source
+
+  3.1 You may copy and Convey verbatim copies of Covered Source, in
+      any medium, provided You retain all Notices.
+
+  3.2 You may modify Covered Source, other than Notices, provided that
+      You irrevocably undertake to make that modified Covered Source
+      available from a Source Location should You Convey a Product in
+      circumstances where the recipient does not otherwise receive a
+      copy of the modified Covered Source. In each case subsection 3.3
+      shall apply.
+
+      You may only delete Notices if they are no longer applicable to
+      the corresponding Covered Source as modified by You and You may
+      add additional Notices applicable to Your modifications.
+      Including Covered Source in a larger work is modifying the
+      Covered Source, and the larger work becomes modified Covered
+      Source.
+
+  3.3 You may Convey modified Covered Source (with the effect that You
+      shall also become a Licensor) provided that You:
+
+       a) retain Notices as required in subsection 3.2;
+
+       b) add a Notice to the modified Covered Source stating that You
+          have modified it, with the date and brief description of how
+          You have modified it;
+
+       c) add a Source Location Notice for the modified Covered Source
+          if You Convey in circumstances where the recipient does not
+          otherwise receive a copy of the modified Covered Source; and
+
+       d) license the modified Covered Source under the terms and
+          conditions of this Licence (or, as set out in subsection
+          8.3, a later version, if permitted by the licence of the
+          original Covered Source). Such modified Covered Source must
+          be licensed as a whole, but excluding Available Components
+          contained in it, which remain licensed under their own
+          applicable licences.
+
+
+4 Making and Conveying Products
+
+You may Make Products, and/or Convey them, provided that You either
+provide each recipient with a copy of the Complete Source or ensure
+that each recipient is notified of the Source Location of the Complete
+Source. That Complete Source is Covered Source, and You must
+accordingly satisfy Your obligations set out in subsection 3.3. If
+specified in a Notice, the Product must visibly and securely display
+the Source Location on it or its packaging or documentation in the
+manner specified in that Notice.
+
+
+5 Research and Development
+
+You may Convey Covered Source, modified Covered Source or Products to
+a legal entity carrying out development, testing or quality assurance
+work on Your behalf provided that the work is performed on terms which
+prevent the entity from both using the Source or Products for its own
+internal purposes and Conveying the Source or Products or any
+modifications to them to any person other than You. Any modifications
+made by the entity shall be deemed to be made by You pursuant to
+subsection 3.2.
+
+
+6 DISCLAIMER AND LIABILITY
+
+  6.1 DISCLAIMER OF WARRANTY -- The Covered Source and any Products
+      are provided 'as is' and any express or implied warranties,
+      including, but not limited to, implied warranties of
+      merchantability, of satisfactory quality, non-infringement of
+      third party rights, and fitness for a particular purpose or use
+      are disclaimed in respect of any Source or Product to the
+      maximum extent permitted by law. The Licensor makes no
+      representation that any Source or Product does not or will not
+      infringe any patent, copyright, trade secret or other
+      proprietary right. The entire risk as to the use, quality, and
+      performance of any Source or Product shall be with You and not
+      the Licensor. This disclaimer of warranty is an essential part
+      of this Licence and a condition for the grant of any rights
+      granted under this Licence.
+
+  6.2 EXCLUSION AND LIMITATION OF LIABILITY -- The Licensor shall, to
+      the maximum extent permitted by law, have no liability for
+      direct, indirect, special, incidental, consequential, exemplary,
+      punitive or other damages of any character including, without
+      limitation, procurement of substitute goods or services, loss of
+      use, data or profits, or business interruption, however caused
+      and on any theory of contract, warranty, tort (including
+      negligence), product liability or otherwise, arising in any way
+      in relation to the Covered Source, modified Covered Source
+      and/or the Making or Conveyance of a Product, even if advised of
+      the possibility of such damages, and You shall hold the
+      Licensor(s) free and harmless from any liability, costs,
+      damages, fees and expenses, including claims by third parties,
+      in relation to such use.
+
+
+7 Patents
+
+  7.1 Subject to the terms and conditions of this Licence, each
+      Licensor hereby grants to You a perpetual, worldwide,
+      non-exclusive, no-charge, royalty-free, irrevocable (except as
+      stated in subsections 7.2 and 8.4) patent licence to Make, have
+      Made, use, offer to sell, sell, import, and otherwise transfer
+      the Covered Source and Products, where such licence applies only
+      to those patent claims licensable by such Licensor that are
+      necessarily infringed by exercising rights under the Covered
+      Source as Conveyed by that Licensor.
+
+  7.2 If You institute patent litigation against any entity (including
+      a cross-claim or counterclaim in a lawsuit) alleging that the
+      Covered Source or a Product constitutes direct or contributory
+      patent infringement, or You seek any declaration that a patent
+      licensed to You under this Licence is invalid or unenforceable
+      then any rights granted to You under this Licence shall
+      terminate as of the date such process is initiated.
+
+
+8 General
+
+  8.1 If any provisions of this Licence are or subsequently become
+      invalid or unenforceable for any reason, the remaining
+      provisions shall remain effective.
+
+  8.2 You shall not use any of the name (including acronyms and
+      abbreviations), image, or logo by which the Licensor or CERN is
+      known, except where needed to comply with section 3, or where
+      the use is otherwise allowed by law. Any such permitted use
+      shall be factual and shall not be made so as to suggest any kind
+      of endorsement or implication of involvement by the Licensor or
+      its personnel.
+
+  8.3 CERN may publish updated versions and variants of this Licence
+      which it considers to be in the spirit of this version, but may
+      differ in detail to address new problems or concerns. New
+      versions will be published with a unique version number and a
+      variant identifier specifying the variant. If the Licensor has
+      specified that a given variant applies to the Covered Source
+      without specifying a version, You may treat that Covered Source
+      as being released under any version of the CERN-OHL with that
+      variant. If no variant is specified, the Covered Source shall be
+      treated as being released under CERN-OHL-S. The Licensor may
+      also specify that the Covered Source is subject to a specific
+      version of the CERN-OHL or any later version in which case You
+      may apply this or any later version of CERN-OHL with the same
+      variant identifier published by CERN.
+
+  8.4 This Licence shall terminate with immediate effect if You fail
+      to comply with any of its terms and conditions.
+
+  8.5 However, if You cease all breaches of this Licence, then Your
+      Licence from any Licensor is reinstated unless such Licensor has
+      terminated this Licence by giving You, while You remain in
+      breach, a notice specifying the breach and requiring You to cure
+      it within 30 days, and You have failed to come into compliance
+      in all material respects by the end of the 30 day period. Should
+      You repeat the breach after receipt of a cure notice and
+      subsequent reinstatement, this Licence will terminate
+      immediately and permanently. Section 6 shall continue to apply
+      after any termination.
+
+  8.6 This Licence shall not be enforceable except by a Licensor
+      acting as such, and third party beneficiary rights are
+      specifically excluded.
