- =======================================================
- This Bootstrap Open Source Licence (the "License") applies to any original work
- of authorship (the "Original Work") whose owner (the "Licensor") has placed the
- following licensing notice adjacent to the copyright notice for the Original
- Work:
- .
- *Licensed under the Bootstrap Open Source Licence version 1.0*
- .
- 1.  **Grant of Copyright License.** Licensor grants You a worldwide,
-     royalty-free, non-exclusive, sublicensable license, for the duration of the
-     copyright in the Original Work, to do the following:
- .
-         a. to reproduce the Original Work in copies, either alone or as part of
-         a collective work;
- .
-         b. to translate, adapt, alter, transform, modify, or arrange the
-         Original Work, thereby creating derivative works ("Derivative Works")
-         based upon the Original Work;
- .
-         c. to distribute or communicate copies of the Original Work and
-         Derivative Works to the public, provided that prior to any such
-         distribution or communication You first place a machine-readable copy
-         of the Source Code of the Original Work and such Derivative Works that
-         You intend to distribute or communicate in an information repository
-         reasonably calculated to permit inexpensive and convenient access
-         thereto by the public (“Information Repository”) for as long as You
-         continue to distribute or communicate said copies, accompanied by an
-         irrevocable offer to license said copies to the public free of charge
-         under this License, said offer valid starting no later than 12 months
-         after You first distribute or communicate said copies;
- .
-     d. to perform the Original Work publicly; and
- .
-     e. to display the Original Work publicly.
- .
- 2.  **Grant of Patent License.** Licensor grants You a worldwide, royalty-free,
- non-exclusive, sublicensable license, under patent claims owned or controlled
- by the Licensor that are embodied in the Original Work as furnished by the
- Licensor, for the duration of the patents, to make, use, sell, offer for sale,
- have made, and import the Original Work and Derivative Works.
- .
- 3.  **Grant of Source Code License.** The "Source Code" for a work means the
- preferred form of the work for making modifications to it and all available
- documentation describing how to modify the work. Licensor agrees to provide a
- machine-readable copy of the Source Code of the Original Work along with each
- copy of the Original Work that Licensor distributes. Licensor reserves the
- right to satisfy this obligation by placing a machine-readable copy of said
- Source Code in an Information Repository for as long as Licensor continues to
- distribute the Original Work.
- .
- 4.  **Exclusions From License Grant.** Neither the names of Licensor, nor the
- names of any contributors to the Original Work, nor any of their trademarks or
- service marks, may be used to endorse or promote products derived from this
- Original Work without express prior permission of the Licensor. Except as
- expressly stated herein, nothing in this License grants any license to
- Licensor's trademarks, copyrights, patents, trade secrets or any other
- intellectual property. No patent license is granted to make, use, sell, offer
- for sale, have made, or import embodiments of any patent claims other than the
- licensed claims defined in Section 2. No license is granted to the trademarks
- of Licensor even if such marks are included in the Original Work. Nothing in
- this License shall be interpreted to prohibit Licensor from licensing under
- terms different from this License any Original Work that Licensor otherwise
- would have a right to license.
- .
- 5.  **External Deployment.** The term "External Deployment" means the use,
- distribution, or communication of the Original Work or Derivative Works in any
- way such that the Original Work or Derivative Works may be used by anyone other
- than You, whether those works are distributed or communicated to those persons
- or made available as an application intended for use over a network. As an
- express condition for the grants of license hereunder, You must treat any
- External Deployment by You of the Original Work or a Derivative Work as a
- distribution under section 1(c).
- .
- 6.  **Attribution Rights.** You must retain, in the Source Code of any
- Derivative Works that You create, all copyright, patent, or trademark notices
- from the Source Code of the Original Work, as well as any notices of licensing
- and any descriptive text identified therein as an "Attribution Notice." You
- must cause the Source Code for any Derivative Works that You create to carry a
- prominent Attribution Notice reasonably calculated to inform recipients that
- You have modified the Original Work.
- .
- 7.  **Warranty of Provenance and Disclaimer of Warranty.** Licensor warrants
- that the copyright in and to the Original Work and the patent rights granted
- herein by Licensor are owned by the Licensor or are sublicensed to You under
- the terms of this License with the permission of the contributor(s) of those
- copyrights and patent rights. Except as expressly stated in the immediately
- preceding sentence, the Original Work is provided under this License on an "AS
- IS" BASIS and WITHOUT WARRANTY, either express or implied, including, without
- limitation, the warranties of non-infringement, merchantability or fitness for
- a particular purpose. THE ENTIRE RISK AS TO THE QUALITY OF THE ORIGINAL WORK IS
- WITH YOU. This DISCLAIMER OF WARRANTY constitutes an essential part of this
- License. No license to the Original Work is granted by this License except
- under this disclaimer.
- .
- 8.  **Limitation of Liability.** Under no circumstances and under no legal
- theory, whether in tort (including negligence), contract, or otherwise, shall
- the Licensor be liable to anyone for any indirect, special, incidental, or
- consequential damages of any character arising as a result of this License or
- the use of the Original Work including, without limitation, damages for loss of
- goodwill, work stoppage, computer failure or malfunction, or any and all other
- commercial damages or losses. This limitation of liability shall not apply to
- the extent applicable law prohibits such limitation.
- .
- 9.  **Acceptance and Termination.** If, at any time, You expressly assented to
- this License, that assent indicates your clear and irrevocable acceptance of
- this License and all of its terms and conditions. If You distribute or
- communicate copies of the Original Work or a Derivative Work, You must make a
- reasonable effort under the circumstances to obtain the express assent of
- recipients to the terms of this License. This License conditions your rights to
- undertake the activities listed in Section 1, including your right to create
- Derivative Works based upon the Original Work, and doing so without honoring
- these terms and conditions is prohibited by copyright law and international
- treaty. Nothing in this License is intended to affect copyright exceptions and
- limitations (including 'fair use' or 'fair dealing'). This License shall
- terminate immediately and You may no longer exercise any of the rights granted
- to You by this License upon your failure to honor the conditions in Section
- 1(c).
- .
- 10.  **Termination for Patent Action.** This License shall terminate
- automatically and You may no longer exercise any of the rights granted to You
- by this License as of the date You commence an action, including a cross-claim
- or counterclaim, against Licensor or any licensee alleging that the Original
- Work infringes a patent. This termination provision shall not apply for an
- action alleging patent infringement by combinations of the Original Work with
- other software or hardware.
- .
- 11.  **Jurisdiction, Venue and Governing Law.** Any action or suit relating to
- this License may be brought only in the courts of a jurisdiction wherein the
- Licensor resides or in which Licensor conducts its primary business, and under
- the laws of that jurisdiction excluding its conflict-of-law provisions. The
- application of the United Nations Convention on Contracts for the International
- Sale of Goods is expressly excluded. Any use of the Original Work outside the
- scope of this License or after its termination shall be subject to the
- requirements and penalties of copyright or patent law in the appropriate
- jurisdiction. This section shall survive the termination of this License.
- .
- 12.  **Attorneys' Fees.** In any action to enforce the terms of this License or
- seeking damages relating thereto, the prevailing party shall be entitled to
- recover its costs and expenses, including, without limitation, reasonable
- attorneys' fees and costs incurred in connection with such action, including
- any appeal of such action. This section shall survive the termination of this
- License.
- .
- 13.  **Miscellaneous.** 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.
- .
- 14.  **Definition of "You" in This License.** "You" throughout this License,
- whether in upper or lower case, means an individual or a legal entity
- exercising rights under, and complying with all of the terms of, this License.
- For legal entities, "You" includes any entity that controls, is controlled by,
- or is under common control with you. For purposes of this definition, "control"
- means (i) the power, direct or indirect, to cause the direction or management
- of such entity, whether by contract or otherwise, or (ii) ownership of fifty

- restricted or conditioned by this License or by law, and Licensor promises not
- to interfere with or be responsible for such uses by You.

- License without modification. Nothing in this License permits You to modify
- this License as applied to the Original Work or to Derivative Works. However,
- You may modify the text of this License and copy, distribute or communicate
- your modified version (the "Modified License") and apply it to other original
- works of authorship subject to the following conditions: (i) You may not
- indicate in any way that your Modified License is the "Bootstrap Open Source
- Licence" or "BOSL" and you may not use those names in the name of your Modified
