copies of the Software, and to permit persons to whom the Software is
furnished to do so, subject to the following conditions:
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:
The above copyright notice and this permission notice shall be included in all
copies or substantial portions of the Software.
a. to reproduce the Original Work in copies, either alone or as part of
a collective work;
THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE
AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER
LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM,
OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE
SOFTWARE.
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
percent (50%) or more of the outstanding shares, or (iii) beneficial ownership
of such entity.
15. **Right to Use.** You may use the Original Work in all ways not otherwise
restricted or conditioned by this License or by law, and Licensor promises not
to interfere with or be responsible for such uses by You.
16. **Modification of This License.** This License is Copyright © 2007 Zooko
Wilcox-O'Hearn. Permission is granted to copy, distribute, or communicate this
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
License; and (ii) You must replace the notice specified in the first paragraph
above with the notice "Licensed under <insert your license name here>" or with
a notice of your own that is not confusingly similar to the notice in this
License.
