# Exhaustive licensing information for files in the Godot Engine repository
# =========================================================================
#
# This file aims at documenting the copyright and license for every source
# file in the Godot Engine repository, and especially outline the files
# whose license differs from the MIT/Expat license used by Godot Engine.
#
# It is written as a machine-readable format following the debian/copyright
# specification. Globbing patterns (e.g. "Files: *") mean that they affect
# all corresponding files (also recursively in subfolders), apart from those
# with a more explicit copyright statement.
#
# Licenses are given with their SPDX identifier, and are all included in
# plain text at the end of this file (in alphabetical order).
#
# Disclaimer for thirdparty libraries:
# ------------------------------------
#
# Licensing details for thirdparty libraries in the 'thirdparty/' directory
# are given in summarized form, i.e. with only the "main" license described
# in the library's license statement. Different licenses of single files or
# code snippets in thirdparty libraries are not documented here.
# For example:
#   Files: ./thirdparty/zlib/
#   Copyright: 1995-2017, Jean-loup Gailly and Mark Adler
#   License: Zlib
# The exact copyright for each file in that library *may* differ, and some
# files or code snippets might be distributed under other compatible licenses
# (e.g. a public domain dedication), but as far as Godot Engine is concerned
# the library is considered as a whole under the Zlib license.
#
# Nota: When linking dynamically against thirdparty libraries instead of
# building them into the Godot binary, you may remove the corresponding
# license details from this file.

 License
 .
 THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
 COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
 COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
 AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
 .
 BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE
 TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY
 BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS
 CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND
 CONDITIONS.
 .
 1. Definitions
 .
 a. "Adaptation" means a work based upon the Work, or upon the Work and
 other pre-existing works, such as a translation, adaptation, derivative
 work, arrangement of music or other alterations of a literary or
 artistic work, or phonogram or performance and includes cinematographic
 adaptations or any other form in which the Work may be recast,
 transformed, or adapted including in any form recognizably derived from
 the original, except that a work that constitutes a Collection will not
 be considered an Adaptation for the purpose of this License. For the
 avoidance of doubt, where the Work is a musical work, performance or
 phonogram, the synchronization of the Work in timed-relation with a
 moving image ("synching") will be considered an Adaptation for the
 purpose of this License.
 .
 b. "Collection" means a collection of literary or artistic works, such
 as encyclopedias and anthologies, or performances, phonograms or
 broadcasts, or other works or subject matter other than works listed in
 Section 1(f) below, which, by reason of the selection and arrangement of
 their contents, constitute intellectual creations, in which the Work is
 included in its entirety in unmodified form along with one or more other
 contributions, each constituting separate and independent works in
 themselves, which together are assembled into a collective whole. A work
 that constitutes a Collection will not be considered an Adaptation (as
 defined above) for the purposes of this License.
 .
 c.  "Distribute" means to make available to the public the original and
 copies of the Work or Adaptation, as appropriate, through sale or other
 transfer of ownership.
 .
 d. "Licensor" means the individual, individuals, entity or entities that
 offer(s) the Work under the terms of this License.
 .
 e. "Original Author" means, in the case of a literary or artistic work,
 the individual, individuals, entity or entities who created the Work or
 if no individual or entity can be identified, the publisher; and in
 addition (i) in the case of a performance the actors, singers,
 musicians, dancers, and other persons who act, sing, deliver, declaim,
 play in, interpret or otherwise perform literary or artistic works or
 expressions of folklore; (ii) in the case of a phonogram the producer
 being the person or legal entity who first fixes the sounds of a
 performance or other sounds; and, (iii) in the case of broadcasts, the
 organization that transmits the broadcast.
 .
 f. "Work" means the literary and/or artistic work offered under the
 terms of this License including without limitation any production in the
 literary, scientific and artistic domain, whatever may be the mode or
 form of its expression including digital form, such as a book, pamphlet
 and other writing; a lecture, address, sermon or other work of the same
 nature; a dramatic or dramatico-musical work; a choreographic work or
 entertainment in dumb show; a musical composition with or without words;
 a cinematographic work to which are assimilated works expressed by a
 process analogous to cinematography; a work of drawing, painting,
 architecture, sculpture, engraving or lithography; a photographic work
 to which are assimilated works expressed by a process analogous to
 photography; a work of applied art; an illustration, map, plan, sketch
 or three-dimensional work relative to geography, topography,
 architecture or science; a performance; a broadcast; a phonogram; a
 compilation of data to the extent it is protected as a copyrightable
 work; or a work performed by a variety or circus performer to the extent
 it is not otherwise considered a literary or artistic work.
 .
 g. "You" means an individual or entity exercising rights under this
 License who has not previously violated the terms of this License with
 respect to the Work, or who has received express permission from the
 Licensor to exercise rights under this License despite a previous
 violation.
 .
 h. "Publicly Perform" means to perform public recitations of the Work
 and to communicate to the public those public recitations, by any means
 or process, including by wire or wireless means or public digital
 performances; to make available to the public Works in such a way that
 members of the public may access these Works from a place and at a place
 individually chosen by them; to perform the Work to the public by any
 means or process and the communication to the public of the performances
 of the Work, including by public digital performance; to broadcast and
 rebroadcast the Work by any means including signs, sounds or images.
 .
 i. "Reproduce" means to make copies of the Work by any means including
 without limitation by sound or visual recordings and the right of
 fixation and reproducing fixations of the Work, including storage of a
 protected performance or phonogram in digital form or other electronic
 medium.
 .
 2. Fair Dealing Rights. Nothing in this License is intended to reduce,
 limit, or restrict any uses free from copyright or rights arising from
 limitations or exceptions that are provided for in connection with the
 copyright protection under copyright law or other applicable laws.
 .
 3. License Grant. Subject to the terms and conditions of this License,
 Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
 perpetual (for the duration of the applicable copyright) license to
 exercise the rights in the Work as stated below:
 .
 a. to Reproduce the Work, to incorporate the Work into one or more
 Collections, and to Reproduce the Work as incorporated in the
 Collections;
 .
 b. to create and Reproduce Adaptations provided that any such
 Adaptation, including any translation in any medium, takes reasonable
 steps to clearly label, demarcate or otherwise identify that changes
 were made to the original Work. For example, a translation could be
 marked "The original work was translated from English to Spanish," or a
 modification could indicate "The original work has been modified.";
 .
 c. to Distribute and Publicly Perform the Work including as incorporated
 in Collections; and,
 .
 d. to Distribute and Publicly Perform Adaptations.
 .
 e. For the avoidance of doubt:
 .
 i. Non-waivable Compulsory License Schemes. In those jurisdictions in
 which the right to collect royalties through any statutory or compulsory
 licensing scheme cannot be waived, the Licensor reserves the exclusive
 right to collect such royalties for any exercise by You of the rights
 granted under this License;
 .
 ii. Waivable Compulsory License Schemes. In those jurisdictions in which
 the right to collect royalties through any statutory or compulsory
 licensing scheme can be waived, the Licensor waives the exclusive right
 to collect such royalties for any exercise by You of the rights granted
 under this License; and,
 .
 iii. Voluntary License Schemes. The Licensor waives the right to collect
 royalties, whether individually or, in the event that the Licensor is a
 member of a collecting society that administers voluntary licensing
 schemes, via that society, from any exercise by You of the rights
 granted under this License.
 .
 The above rights may be exercised in all media and formats whether now
 known or hereafter devised. The above rights include the right to make
 such modifications as are technically necessary to exercise the rights
 in other media and formats. Subject to Section 8(f), all rights not
 expressly granted by Licensor are hereby reserved.
 .
 4. Restrictions. The license granted in Section 3 above is expressly
 made subject to and limited by the following restrictions:
 .
 a. You may Distribute or Publicly Perform the Work only under the terms
 of this License. You must include a copy of, or the Uniform Resource
 Identifier (URI) for, this License with every copy of the Work You
 Distribute or Publicly Perform. You may not offer or impose any terms on
 the Work that restrict the terms of this License or the ability of the
 recipient of the Work to exercise the rights granted to that recipient
 under the terms of the License. You may not sublicense the Work. You
 must keep intact all notices that refer to this License and to the
 disclaimer of warranties with every copy of the Work You Distribute or
 Publicly Perform. When You Distribute or Publicly Perform the Work, You
 may not impose any effective technological measures on the Work that
 restrict the ability of a recipient of the Work from You to exercise the
 rights granted to that recipient under the terms of the License. This
 Section 4(a) applies to the Work as incorporated in a Collection, but
 this does not require the Collection apart from the Work itself to be
 made subject to the terms of this License. If You create a Collection,
 upon notice from any Licensor You must, to the extent practicable,
 remove from the Collection any credit as required by Section 4(b), as
 requested. If You create an Adaptation, upon notice from any Licensor
 You must, to the extent practicable, remove from the Adaptation any
 credit as required by Section 4(b), as requested.
 .
 b. If You Distribute, or Publicly Perform the Work or any Adaptations or
 Collections, You must, unless a request has been made pursuant to
 Section 4(a), keep intact all copyright notices for the Work and
 provide, reasonable to the medium or means You are utilizing: (i) the
 name of the Original Author (or pseudonym, if applicable) if supplied,
 and/or if the Original Author and/or Licensor designate another party or
 parties (e.g., a sponsor institute, publishing entity, journal) for
 attribution ("Attribution Parties") in Licensor's copyright notice,
 terms of service or by other reasonable means, the name of such party or
 parties; (ii) the title of the Work if supplied; (iii) to the extent
 reasonably practicable, the URI, if any, that Licensor specifies to be
 associated with the Work, unless such URI does not refer to the
 copyright notice or licensing information for the Work; and (iv) ,
 consistent with Section 3(b), in the case of an Adaptation, a credit
 identifying the use of the Work in the Adaptation (e.g., "French
 translation of the Work by Original Author," or "Screenplay based on
 original Work by Original Author"). The credit required by this Section
 4 (b) may be implemented in any reasonable manner; provided, however,
 that in the case of a Adaptation or Collection, at a minimum such credit
 will appear, if a credit for all contributing authors of the Adaptation
 or Collection appears, then as part of these credits and in a manner at
 least as prominent as the credits for the other contributing authors.
 For the avoidance of doubt, You may only use the credit required by this
 Section for the purpose of attribution in the manner set out above and,
 by exercising Your rights under this License, You may not implicitly or
 explicitly assert or imply any connection with, sponsorship or
 endorsement by the Original Author, Licensor and/or Attribution Parties,
 as appropriate, of You or Your use of the Work, without the separate,
 express prior written permission of the Original Author, Licensor and/or
 Attribution Parties.
 .
 c. Except as otherwise agreed in writing by the Licensor or as may be
 otherwise permitted by applicable law, if You Reproduce, Distribute or
 Publicly Perform the Work either by itself or as part of any Adaptations
 or Collections, You must not distort, mutilate, modify or take other
 derogatory action in relation to the Work which would be prejudicial to
 the Original Author's honor or reputation. Licensor agrees that in those
 jurisdictions (e.g. Japan), in which any exercise of the right granted
 in Section 3(b) of this License (the right to make Adaptations) would be
 deemed to be a distortion, mutilation, modification or other derogatory
 action prejudicial to the Original Author's honor and reputation, the
 Licensor will waive or not assert, as appropriate, this Section, to the
 fullest extent permitted by the applicable national law, to enable You
 to reasonably exercise Your right under Section 3(b) of this License
 (right to make Adaptations) but not otherwise.
 .
 5. Representations, Warranties and Disclaimer
 .
 UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
 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, MERCHANTIBILITY,
 FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
 LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
 WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE
 EXCLUSION OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
 .
 6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
 LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
 ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
 ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
 BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
 .
 7. Termination
 .
 a. This License and the rights granted hereunder will terminate
 automatically upon any breach by You of the terms of this License.
 Individuals or entities who have received Adaptations or Collections
 from You under this License, however, will not have their licenses
 terminated provided such individuals or entities remain in full
 compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
 survive any termination of this License.
 .
 b. Subject to the above terms and conditions, the license granted here
 is perpetual (for the duration of the applicable copyright in the Work).
 Notwithstanding the above, Licensor reserves the right to release the
 Work under different license terms or to stop distributing the Work at
 any time; provided, however that any such election will not serve to
 withdraw this License (or any other license that has been, or is
 required to be, granted under the terms of this License), and this
 License will continue in full force and effect unless terminated as
 stated above.
 .
 8. Miscellaneous
 .
 a. Each time You Distribute or Publicly Perform the Work or a
 Collection, the Licensor offers to the recipient a license to the Work
 on the same terms and conditions as the license granted to You under
 this License.
 .
 b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
 offers to the recipient a license to the original Work on the same terms
 and conditions as the license granted to You under this License.
 .
 c. If any provision of this License is invalid or unenforceable under
 applicable law, it shall not affect the validity or enforceability of
 the remainder of the terms of this License, and without further action
 by the parties to this agreement, such provision shall be reformed to
 the minimum extent necessary to make such provision valid and
 enforceable.
 .
 d. No term or provision of this License shall be deemed waived and no
 breach consented to unless such waiver or consent shall be in writing
 and signed by the party to be charged with such waiver or consent. This
 License constitutes the entire agreement between the parties with
 respect to the Work licensed here. There are no understandings,
 agreements or representations with respect to the Work not specified
 here. Licensor shall not be bound by any additional provisions that may
 appear in any communication from You.
 .
 e. This License may not be modified without the mutual written agreement
 of the Licensor and You.
 .
 f. The rights granted under, and the subject matter referenced, in this
 License were drafted utilizing the terminology of the Berne Convention
 for the Protection of Literary and Artistic Works (as amended on

 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.
 .

License: OFL-1.1
 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.
 .

 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

 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.

 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
