What follows is quoted, not written. It is set narrow, as an appendix, and reproduced exactly as it was given.

The SIL Open Font License, version 1.1, which covers Caveat,
Patrick Hand and Vollkorn. The three copyright notices it
asks for are on the type page.

This Font Software is licensed under the SIL Open Font
License, Version 1.1.
This license is copied below, and is also available with a
FAQ at:

-----------------------------------------------------------
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

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,
and issue tracking systems that are managed by, or on behalf
of, the
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.

Creative Commons Attribution 4.0 International Public
License

By exercising the Licensed Rights (defined below), You
accept and agree
to be bound by the terms and conditions of this Creative
Commons
Attribution 4.0 International Public License ("Public
License"). To the extent this Public License may be
interpreted as a
contract, You are granted the Licensed Rights in
consideration of Your
acceptance of these terms and conditions, and the Licensor
grants You
such rights in consideration of benefits the Licensor
receives from
making the Licensed Material available under these terms and
conditions.

Section 1 -- Definitions.

a. Adapted Material means material subject to Copyright and
Similar
Rights that is derived from or based upon the Licensed
Material
and in which the Licensed Material is translated, altered,
arranged, transformed, or otherwise modified in a manner
requiring
permission under the Copyright and Similar Rights held by
the
Licensor. For purposes of this Public License, where the
Licensed
Material is a musical work, performance, or sound recording,
Adapted Material is always produced where the Licensed
Material is
synched in timed relation with a moving image.

b. Adapter's License means the license You apply to Your
Copyright
and Similar Rights in Your contributions to Adapted Material
in
accordance with the terms and conditions of this Public
License.

c. Copyright and Similar Rights means copyright and/or
similar rights
closely related to copyright including, without limitation,
performance, broadcast, sound recording, and Sui Generis
Database
Rights, without regard to how the rights are labeled or
categorized. For purposes of this Public License, the rights
specified in Section 2(b)(1)-(2) are not Copyright and
Similar
Rights.

d. Effective Technological Measures means those measures
that, in the
absence of proper authority, may not be circumvented under
laws
fulfilling obligations under Article 11 of the WIPO
Copyright
Treaty adopted on December 20, 1996, and/or similar
international
agreements.

e. Exceptions and Limitations means fair use, fair dealing,
and/or
any other exception or limitation to Copyright and Similar
Rights
that applies to Your use of the Licensed Material.

f. Licensed Material means the artistic or literary work,
database,
or other material to which the Licensor applied this Public
License.

g. Licensed Rights means the rights granted to You subject
to the
terms and conditions of this Public License, which are
limited to
all Copyright and Similar Rights that apply to Your use of
the
Licensed Material and that the Licensor has authority to
license.

h. Licensor means the individual(s) or entity(ies) granting
rights
under this Public License.

i. Share means to provide material to the public by any
means or
process that requires permission under the Licensed Rights,
such
as reproduction, public display, public performance,
distribution,
dissemination, communication, or importation, and to make
material
available to the public including in ways that members of
the
public may access the material from a place and at a time
individually chosen by them.

j. Sui Generis Database Rights means rights other than
copyright
resulting from Directive 96/9/EC of the European Parliament
and of
the Council of 11 March 1996 on the legal protection of
databases,
as amended and/or succeeded, as well as other essentially
equivalent rights anywhere in the world.

k. You means the individual or entity exercising the
Licensed Rights
under this Public License. Your has a corresponding meaning.

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. 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.

4. If You Share Adapted Material You produce, the Adapter's
License You apply must not prevent recipients of the Adapted
Material from complying with this Public License.

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; 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.

The CC0-1.0 license, as the engine reports it.

CC0 1.0 Universal

Statement of Purpose

The laws of most jurisdictions throughout the world
automatically confer
exclusive Copyright and Related Rights (defined below) upon
the creator and
subsequent owner(s) (each and all, an "owner") of an
original work of
authorship and/or a database (each, a "Work").

Certain owners wish to permanently relinquish those rights
to a Work for the
purpose of contributing to a commons of creative, cultural
and scientific
works ("Commons") that the public can reliably and without
fear of later
claims of infringement build upon, modify, incorporate in
other works, reuse
and redistribute as freely as possible in any form
whatsoever and for any
purposes, including without limitation commercial purposes.
These owners may
contribute to the Commons to promote the ideal of a free
culture and the
further production of creative, cultural and scientific
works, or to gain
reputation or greater distribution for their Work in part
through the use and
efforts of others.

For these and/or other purposes and motivations, and without
any expectation
of additional consideration or compensation, the person
associating CC0 with a
Work (the "Affirmer"), to the extent that he or she is an
owner of Copyright
and Related Rights in the Work, voluntarily elects to apply
CC0 to the Work
and publicly distribute the Work under its terms, with
knowledge of his or her
Copyright and Related Rights in the Work and the meaning and
intended legal
effect of CC0 on those rights.

1. Copyright and Related Rights. A Work made available under
CC0 may be
protected by copyright and related or neighboring rights
("Copyright and
Related Rights"). Copyright and Related Rights include, but
are not limited
to, the following:

i. the right to reproduce, adapt, distribute, perform,
display, communicate,
and translate a Work;

ii. moral rights retained by the original author(s) and/or
performer(s);

iii. publicity and privacy rights pertaining to a person's
image or likeness
depicted in a Work;

iv. rights protecting against unfair competition in regards
to a Work,
subject to the limitations in paragraph 4(a), below;

v. rights protecting the extraction, dissemination, use and
reuse of data in
a Work;

vi. database rights (such as those arising under Directive
96/9/EC of the
European Parliament and of the Council of 11 March 1996 on
the legal
protection of databases, and under any national
implementation thereof,
including any amended or successor version of such
directive); and

vii. other similar, equivalent or corresponding rights
throughout the world
based on applicable law or treaty, and any national
implementations thereof.

2. Waiver. To the greatest extent permitted by, but not in
contravention of,
applicable law, Affirmer hereby overtly, fully, permanently,
irrevocably and
unconditionally waives, abandons, and surrenders all of
Affirmer's Copyright
and Related Rights and associated claims and causes of
action, whether now
known or unknown (including existing as well as future
claims and causes of
action), in the Work (i) in all territories worldwide, (ii)
for the maximum
duration provided by applicable law or treaty (including
future time
extensions), (iii) in any current or future medium and for
any number of
copies, and (iv) for any purpose whatsoever, including
without limitation
commercial, advertising or promotional purposes (the
"Waiver"). Affirmer makes
the Waiver for the benefit of each member of the public at
large and to the
detriment of Affirmer's heirs and successors, fully
intending that such Waiver
shall not be subject to revocation, rescission,
cancellation, termination, or
any other legal or equitable action to disrupt the quiet
enjoyment of the Work
by the public as contemplated by Affirmer's express
Statement of Purpose.

3. Public License Fallback. Should any part of the Waiver
for any reason be
judged legally invalid or ineffective under applicable law,
then the Waiver
shall be preserved to the maximum extent permitted taking
into account
Affirmer's express Statement of Purpose. In addition, to the
extent the Waiver
is so judged Affirmer hereby grants to each affected person
a royalty-free,
non transferable, non sublicensable, non exclusive,
irrevocable and
unconditional license to exercise Affirmer's Copyright and
Related Rights in
the Work (i) in all territories worldwide, (ii) for the
maximum duration
provided by applicable law or treaty (including future time
extensions), (iii)
in any current or future medium and for any number of
copies, and (iv) for any
purpose whatsoever, including without limitation commercial,
advertising or
promotional purposes (the "License"). The License shall be
deemed effective as
of the date CC0 was applied by Affirmer to the Work. Should
any part of the
License for any reason be judged legally invalid or
ineffective under
applicable law, such partial invalidity or ineffectiveness
shall not
invalidate the remainder of the License, and in such case
Affirmer hereby
affirms that he or she will not (i) exercise any of his or
her remaining
Copyright and Related Rights in the Work or (ii) assert any
associated claims
and causes of action with respect to the Work, in either
case contrary to
Affirmer's express Statement of Purpose.

4. Limitations and Disclaimers.

a. No trademark or patent rights held by Affirmer are
waived, abandoned,
surrendered, licensed or otherwise affected by this
document.

b. Affirmer offers the Work as-is and makes no
representations or warranties
of any kind concerning the Work, express, implied, statutory
or otherwise,
including without limitation warranties of title,
merchantability, fitness
for a particular purpose, non infringement, or the absence
of latent or
other defects, accuracy, or the present or absence of
errors, whether or not
discoverable, all to the greatest extent permissible under
applicable law.

c. Affirmer disclaims responsibility for clearing rights of
other persons
that may apply to the Work or any use thereof, including
without limitation
any person's Copyright and Related Rights in the Work.
Further, Affirmer
disclaims responsibility for obtaining any necessary
consents, permissions
or other rights required for any use of the Work.

d. Affirmer understands and acknowledges that Creative
Commons is not a
party to this document and has no duty or obligation with
respect to this
CC0 or use of the Work.

The FreeType Project LICENSE
----------------------------

2000-Feb-08

Copyright 1996-2000 by
David Turner, Robert Wilhelm, and Werner Lemberg



Introduction
============

The FreeType  Project is distributed in  several archive
packages;
some of them may contain, in addition to the FreeType font
engine,
various tools and  contributions which rely on, or  relate
to, the
FreeType Project.

This  license applies  to all  files found  in such 
packages, and
which do not  fall under their own explicit  license.  The
license
affects  thus  the  FreeType   font  engine,  the  test 
programs,
documentation and makefiles, at the very least.

This  license   was  inspired  by  the  BSD,   Artistic, 
and  IJG
(Independent JPEG  Group) licenses, which  all encourage
inclusion
and  use of  free  software in  commercial  and freeware 
products
alike.  As a consequence, its main points are that:

o We don't promise that this software works. However, we
will be
interested in any kind of bug reports. (`as is'
distribution)

o You can  use this software for whatever you  want, in
parts or
full form, without having to pay us. (`royalty-free' usage)

o You may not pretend that  you wrote this software.  If you
use
it, or  only parts of it,  in a program,  you must
acknowledge
somewhere  in  your  documentation  that  you  have  used 
the
FreeType code. (`credits')

We  specifically  permit  and  encourage  the  inclusion  of
this
software, with  or without modifications,  in commercial
products.
We  disclaim  all warranties  covering  The  FreeType
Project  and
assume no liability related to The FreeType Project.


Legal Terms
===========

0. Definitions
--------------

Throughout this license,  the terms `package', `FreeType
Project',
and  `FreeType  archive' refer  to  the  set  of files 
originally
distributed  by the  authors  (David Turner,  Robert
Wilhelm,  and
Werner Lemberg) as the `FreeType Project', be they named as
alpha,
beta or final release.

`You' refers to  the licensee, or person using  the project,
where
`using' is a generic term including compiling the project's
source
code as  well as linking it  to form a  `program' or
`executable'.
This  program is  referred to  as  `a program  using the 
FreeType
engine'.

This  license applies  to all  files distributed  in  the
original
FreeType  Project,   including  all  source   code, 
binaries  and
documentation,  unless  otherwise  stated   in  the  file 
in  its
original, unmodified form as  distributed in the original
archive.
If you are  unsure whether or not a particular  file is
covered by
this license, you must contact us to verify this.

The FreeType  Project is copyright (C) 1996-2000  by David
Turner,
Robert Wilhelm, and Werner Lemberg.  All rights reserved
except as
specified below.

1. No Warranty
--------------

THE FREETYPE PROJECT  IS PROVIDED `AS IS' WITHOUT  WARRANTY
OF ANY
KIND, EITHER  EXPRESS OR IMPLIED,  INCLUDING, BUT NOT 
LIMITED TO,
WARRANTIES  OF  MERCHANTABILITY   AND  FITNESS  FOR  A 
PARTICULAR
PURPOSE.  IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT
HOLDERS
BE LIABLE  FOR ANY DAMAGES CAUSED  BY THE USE OR  THE
INABILITY TO
USE, OF THE FREETYPE PROJECT.

2. Redistribution
-----------------

This  license  grants  a  worldwide, royalty-free, 
perpetual  and
irrevocable right  and license to use,  execute, perform,
compile,
display,  copy,   create  derivative  works   of, 
distribute  and
sublicense the  FreeType Project (in  both source and 
object code
forms)  and  derivative works  thereof  for  any  purpose;
and  to
authorize others  to exercise  some or all  of the  rights
granted
herein, subject to the following conditions:

o Redistribution  of source code  must retain this  license
file
(`LICENSE.TXT') unaltered; any additions, deletions or
changes
to   the  original   files  must   be  clearly   indicated 
in
accompanying  documentation.   The  copyright notices  of 
the
unaltered, original  files must be preserved in  all copies
of
source files.

o Redistribution in binary form must provide a  disclaimer 
that
states  that  the software is based in part of the work of
the
FreeType Team,  in  the  distribution  documentation.  We
also
encourage you to put an URL to the FreeType web page  in 
your
documentation, though this isn't mandatory.

These conditions  apply to any  software derived from or 
based on
the FreeType Project,  not just the unmodified files.   If
you use
our work, you  must acknowledge us.  However, no  fee need
be paid
to us.

3. Advertising
--------------

Neither the  FreeType authors and  contributors nor you 
shall use
the name of the  other for commercial, advertising, or
promotional
purposes without specific prior written permission.

We suggest,  but do not require, that  you use one or  more
of the
following phrases to refer  to this software in your
documentation
or advertising  materials: `FreeType Project',  `FreeType
Engine',
`FreeType library', or `FreeType Distribution'.

As  you have  not signed  this license,  you are  not 
required to
accept  it.   However,  as  the FreeType  Project  is 
copyrighted
material, only  this license, or  another one contracted 
with the
authors, grants you  the right to use, distribute,  and
modify it.
Therefore,  by  using,  distributing,  or modifying  the 
FreeType
Project, you indicate that you understand and accept all the
terms
of this license.

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

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.

*  statutory, including, without limitation, warranties that
the       *
*  Covered Software is free of defects, merchantable, fit

to the     *

respect, You     *
*  (not any Contributor) assume the cost of any necessary

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

likely to look
for such a notice.

You may add additional accurate notices of copyright
ownership.

Exhibit B - "Incompatible With Secondary Licenses" Notice

The OFL-1.1 license, as the engine reports it.

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

Permission is granted to anyone to use this software for any

you must not
claim that you wrote the original software. If you use this

The glslang license, as the engine reports it.

Here, glslang proper means core GLSL parsing, HLSL parsing,
and SPIR-V code
generation. Glslang proper requires use of a number of
licenses, one that covers
preprocessing and others that covers non-preprocessing.

Bison was removed long ago. You can build glslang from the
source grammar,
using tools of your choice, without using bison or any bison
files.

Other parts, outside of glslang proper, include:

- gl_types.h, only needed for OpenGL-like reflection, and
can be left out of
a parse and codegen project.  See it for its license.

- update_glslang_sources.py, which is not part of the
project proper and does
not need to be used.

- the SPIR-V "remapper", which is optional, but has the same
license as
glslang proper

- Google tests and SPIR-V tools, and anything in the
external subdirectory
are external and optional; see them for their respective
licenses.

thereof
as a parser skeleton.  Alternatively, if you modify or
redistribute
the parser skeleton itself, you may (at your option) remove
this
special exception, which will cause the skeleton and the
resulting
Bison output files to be licensed under the GNU General
Public
License without this special exception.

This special exception was added by the Free Software
Foundation in
version 2.2 of Bison.
