Project Homepage

      NSS is available under the Mozilla Public License, version 2, a copy of which
      is below.

      Note on GPL Compatibility
      -------------------------

      The MPL 2, section 3.3, permits you to combine NSS with code under the GNU
      General Public License (GPL) version 2, or any later version of that
      license, to make a Larger Work, and distribute the result under the GPL.
      The only condition is that you must also make NSS, and any changes you
      have made to it, available to recipients under the terms of the MPL 2 also.

      Anyone who receives the combined code from you does not have to continue
      to dual licence in this way, and may, if they wish, distribute under the
      terms of either of the two licences - either the MPL alone or the GPL
      alone. However, we discourage people from distributing copies of NSS under
      the GPL alone, because it means that any improvements they make cannot be
      reincorporated into the main version of NSS. There is never a need to do
      this for license compatibility reasons.

      Note on LGPL Compatibility
      --------------------------

      The above also applies to combining MPLed code in a single library with
      code under the GNU Lesser General Public License (LGPL) version 2.1, or
      any later version of that license. If the LGPLed code and the MPLed code
      are not in the same library, then the copyleft coverage of the two
      licences does not overlap, so no issues arise.

      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.

      *  Covered Software is provided under this License on an "as is"       *
      *  basis, without warranty of any kind, either expressed, implied, or  *
      *  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.         *
      *                                                                      *

      *  permitted above, be liable to You for any direct, indirect,         *
      *  special, incidental, or consequential damages of any character      *
      *  including, without limitation, damages for lost profits, loss of    *

      *  and all other commercial damages or losses, even if such party      *

      *  incidental or consequential damages, so this exclusion and          *

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

      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
      steward.

      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
      notice described in Exhibit B of this License must be attached.

      Exhibit A - Source Code Form License Notice
      -------------------------------------------

        License, v. 2.0. If a copy of the MPL was not distributed with this
        file, You can obtain one at http://mozilla.org/MPL/2.0/.

      If it is not possible or desirable to put the notice in a particular
      file, then You may include the notice in a location (such as a LICENSE
      file in a relevant directory) where a recipient would be likely to look
      for such a notice.

      You may add additional accurate notices of copyright ownership.

      Exhibit B - "Incompatible With Secondary Licenses" Notice
      ---------------------------------------------------------

        This Source Code Form is "Incompatible With Secondary Licenses", as
        defined by the Mozilla Public License, v. 2.0.
