SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and open
framework in which fonts may be shared and improved in partnership with
others.

The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The fonts,
including any derivative works, can be bundled, embedded, redistributed and/or
sold with any software provided that any reserved names are not used by
derivative works. The fonts and derivatives, however, cannot be released under
any other type of license. The requirement for fonts to remain under this
license does not apply to any document created using the fonts or their
derivatives.

DEFINITIONS
"Font Software" refers to the set of files released by the Copyright Holder(s)
under this license and clearly marked as such. This may include source files,
build scripts and documentation.

"Reserved Font Name" refers to any names specified as such after the copyright
statement(s).

"Original Version" refers to the collection of Font Software components as
distributed by the Copyright Holder(s).

"Modified Version" refers to any derivative made by adding to, deleting, or
substituting -- in part or in whole -- any of the components of the Original
Version, by changing formats or by porting the Font Software to a new
environment.

"Author" refers to any designer, engineer, programmer, technical writer or
other person who contributed to the Font Software.

PERMISSION & CONDITIONS
Permission is hereby granted, free of charge, to any person obtaining a copy of
the Font Software, to use, study, copy, merge, embed, modify, redistribute, and
sell modified and unmodified copies of the Font Software, subject to the
following conditions:

1) Neither the Font Software nor any of its individual components, in Original
or Modified Versions, may be sold by itself.

2) Original or Modified Versions of the Font Software may be bundled,
redistributed and/or sold with any software, provided that each copy contains
the above copyright notice and this license. These can be included either as
stand-alone text files, human-readable headers or in the appropriate
machine-readable metadata fields within text or binary files as long as those
fields can be easily viewed by the user.

3) No Modified Version of the Font Software may use the Reserved Font Name(s)
unless explicit written permission is granted by the corresponding Copyright
Holder. This restriction only applies to the primary font name as presented to
the users.

4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font Software
shall not be used to promote, endorse or advertise any Modified Version,
except to acknowledge the contribution(s) of the Copyright Holder(s) and the
Author(s) or with their explicit written permission.

5) The Font Software, modified or unmodified, in part or in whole, must be
distributed entirely under this license, and must not be distributed under any
other license. The requirement for fonts to remain under this license does not
apply to any document created using the Font Software.

TERMINATION
This license becomes null and void if any of the above conditions are not met.

DISCLAIMER
THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT OF COPYRIGHT, PATENT,
TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE COPYRIGHT HOLDER BE LIABLE FOR
ANY CLAIM, DAMAGES OR OTHER LIABILITY, INCLUDING ANY GENERAL, SPECIAL,
INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, WHETHER IN AN ACTION OF
CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF THE USE OR INABILITY TO USE
THE FONT SOFTWARE OR FROM OTHER DEALINGS IN THE FONT SOFTWARE.

The full Eclipse Public License 2.0 text follows.

# Eclipse Public License - v 2.0

THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE
PUBLIC LICENSE (“AGREEMENT”). ANY USE, REPRODUCTION OR DISTRIBUTION OF
THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.

## 1. DEFINITIONS

“Contribution” means:

-   a\) in the case of the initial Contributor, the initial content
    Distributed under this Agreement, and
-   b\) in the case of each subsequent Contributor:
    -   i\) changes to the Program, and
    -   ii\) additions to the Program;

    where such changes and/or additions to the Program originate from
    and are Distributed by that particular Contributor. A Contribution
    “originates” from a Contributor if it was added to the Program by
    such Contributor itself or anyone acting on such Contributor's
    behalf. Contributions do not include changes or additions to the
    Program that are not Modified Works.

“Contributor” means any person or entity that Distributes the Program.

“Licensed Patents” mean patent claims licensable by a Contributor which
are necessarily infringed by the use or sale of its Contribution alone
or when combined with the Program.

“Program” means the Contributions Distributed in accordance with this
Agreement.

“Recipient” means anyone who receives the Program under this Agreement
or any Secondary License (as applicable), including Contributors.

“Derivative Works” shall mean any work, whether in Source Code or other
form, that is based on (or derived from) the Program and for which the
editorial revisions, annotations, elaborations, or other modifications
represent, as a whole, an original work of authorship.

“Modified Works” shall mean any work in Source Code or other form that
results from an addition to, deletion from, or modification of the
contents of the Program, including, for purposes of clarity any new file
in Source Code form that contains any contents of the Program. Modified
Works shall not include works that contain only declarations,
interfaces, types, classes, structures, or files of the Program solely
in each case in order to link to, bind by name, or subclass the Program
or Modified Works thereof.

“Distribute” means the acts of a) distributing or b) making available in
any manner that enables the transfer of a copy.

“Source Code” means the form of a Program preferred for making
modifications, including but not limited to software source code,
documentation source, and configuration files.

“Secondary License” means either the GNU General Public License, Version
2.0, or any later versions of that license, including any exceptions or
additional permissions as identified by the initial Contributor.

## 2. GRANT OF RIGHTS

-   a\) Subject to the terms of this Agreement, each Contributor hereby
    grants Recipient a non-exclusive, worldwide, royalty-free copyright
    license to reproduce, prepare Derivative Works of, publicly display,
    publicly perform, Distribute and sublicense the Contribution of such
    Contributor, if any, and such Derivative Works.
-   b\) Subject to the terms of this Agreement, each Contributor hereby
    grants Recipient a non-exclusive, worldwide, royalty-free patent license
    under Licensed Patents to make, use, sell, offer to sell, import and
    otherwise transfer the Contribution of such Contributor, if any, in
    Source Code or other form. This patent license shall apply to the
    combination of the Contribution and the Program if, at the time the
    Contribution is added by the Contributor, such addition of the
    Contribution causes such combination to be covered by the
    Licensed Patents. The patent license shall not apply to any other
    combinations which include the Contribution. No hardware per se is
    licensed hereunder.
-   c\) Recipient understands that although each Contributor grants the
    licenses to its Contributions set forth herein, no assurances are
    provided by any Contributor that the Program does not infringe the
    patent or other intellectual property rights of any other entity. Each
    Contributor disclaims any liability to Recipient for claims brought by
    any other entity based on infringement of intellectual property rights
    or otherwise. As a condition to exercising the rights and licenses
    granted hereunder, each Recipient hereby assumes sole responsibility to
    secure any other intellectual property rights needed, if any. For
    example, if a third party patent license is required to allow Recipient
    to Distribute the Program, it is Recipient's responsibility to acquire
    that license before distributing the Program.
-   d\) Each Contributor represents that to its knowledge it has sufficient
    copyright rights in its Contribution, if any, to grant the copyright
    license set forth in this Agreement.
-   e\) Notwithstanding the terms of any Secondary License, no Contributor
    makes additional grants to any Recipient (other than those set forth in
    this Agreement) as a result of such Recipient's receipt of the Program
    under the terms of a Secondary License (if permitted under the terms of
    Section 3).

## 3. REQUIREMENTS

3.1 If a Contributor Distributes the Program in any form, then:

-   a\) the Program must also be made available as Source Code, in accordance
    with section 3.2, and the Contributor must accompany the Program with a
    statement that the Source Code for the Program is available under this
    Agreement, and informs Recipients how to obtain it in a reasonable
    manner on or through a medium customarily used for software exchange;
    and
-   b\) the Contributor may Distribute the Program under a license different
    than this Agreement, provided that such license:
    -   i\) effectively disclaims on behalf of all other Contributors all
        warranties and conditions, express and implied, including warranties or
        conditions of title and non-infringement, and implied warranties or
        conditions of merchantability and fitness for a particular purpose;
    -   ii\) effectively excludes on behalf of all other Contributors all
        liability for damages, including direct, indirect, special, incidental
        and consequential damages, such as lost profits;
    -   iii\) does not attempt to limit or alter the recipients' rights in the
        Source Code under section 3.2; and
    -   iv\) requires any subsequent distribution of the Program by any party to
        be under a license that satisfies the requirements of this section 3.

3.2 When the Program is Distributed as Source Code:

-   a\) it must be made available under this Agreement, or if the Program (i)
    is combined with other material in a separate file or files made
    available under a Secondary License, and (ii) the initial Contributor
    attached to the Source Code the notice described in Exhibit A of this
    Agreement, then the Program may be made available under the terms of
    such Secondary Licenses, and
-   b\) a copy of this Agreement must be included with each copy of
    the Program.

3.3 Contributors may not remove or alter any copyright, patent,
trademark, attribution notices, disclaimers of warranty, or limitations
of liability (‘notices’) contained within the Program from any copy of
the Program which they Distribute, provided that Contributors may add
their own appropriate notices.

## 4. COMMERCIAL DISTRIBUTION

Commercial distributors of software may accept certain responsibilities
with respect to end users, business partners and the like. While this
license is intended to facilitate the commercial use of the Program, the
Contributor who includes the Program in a commercial product offering
should do so in a manner which does not create potential liability for
other Contributors. Therefore, if a Contributor includes the Program in
a commercial product offering, such Contributor (“Commercial
Contributor”) hereby agrees to defend and indemnify every other
Contributor (“Indemnified Contributor”) against any losses, damages and
costs (collectively “Losses”) arising from claims, lawsuits and other
legal actions brought by a third party against the Indemnified
Contributor to the extent caused by the acts or omissions of such
Commercial Contributor in connection with its distribution of the
Program in a commercial product offering. The obligations in this
section do not apply to any claims or Losses relating to any actual or
alleged intellectual property infringement. In order to qualify, an
Indemnified Contributor must: a) promptly notify the Commercial
Contributor in writing of such claim, and b) allow the Commercial
Contributor to control, and cooperate with the Commercial Contributor
in, the defense and any related settlement negotiations. The Indemnified
Contributor may participate in any such claim at its own expense.

For example, a Contributor might include the Program in a commercial
product offering, Product X. That Contributor is then a Commercial
Contributor. If that Commercial Contributor then makes performance
claims, or offers warranties related to Product X, those performance
claims and warranties are such Commercial Contributor's responsibility
alone. Under this section, the Commercial Contributor would have to
defend claims against the other Contributors related to those
performance claims and warranties, and if a court requires any other
Contributor to pay any damages as a result, the Commercial Contributor
must pay those damages.

## 5. NO WARRANTY {#warranty}

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
PERMITTED BY APPLICABLE LAW, THE PROGRAM IS PROVIDED ON AN “AS IS”
BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR
IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF
TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE. Each Recipient is solely responsible for determining the
appropriateness of using and distributing the Program and assumes all
risks associated with its exercise of rights under this Agreement,
including but not limited to the risks and costs of program errors,
compliance with applicable laws, damage to or loss of data, programs or
equipment, and unavailability or interruption of operations.

## 6. DISCLAIMER OF LIABILITY {#disclaimer}

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
PERMITTED BY APPLICABLE LAW, NEITHER RECIPIENT NOR ANY CONTRIBUTORS
SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST
PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN
CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE)
ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE
EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

## 7. GENERAL

If any provision of this Agreement is invalid or unenforceable under
applicable law, it shall not affect the validity or enforceability of
the remainder of the terms of this Agreement, and without further action
by the parties hereto, such provision shall be reformed to the minimum
extent necessary to make such provision valid and enforceable.

If Recipient institutes patent litigation against any entity (including
a cross-claim or counterclaim in a lawsuit) alleging that the Program
itself (excluding combinations of the Program with other software or
hardware) infringes such Recipient's patent(s), then such Recipient's
rights granted under Section 2(b) shall terminate as of the date such
litigation is filed.

All Recipient's rights under this Agreement shall terminate if it fails
to comply with any of the material terms or conditions of this Agreement
and does not cure such failure in a reasonable period of time after
becoming aware of such noncompliance. If all Recipient's rights under
this Agreement terminate, Recipient agrees to cease use and distribution
of the Program as soon as reasonably practicable. However, Recipient's
obligations under this Agreement and any licenses granted by Recipient
relating to the Program shall continue and survive.

Everyone is permitted to copy and distribute copies of this Agreement,
but in order to avoid inconsistency the Agreement is copyrighted and may

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,

      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
