This product includes software developed by third parties. The notices below
are the attribution those licences require. Each dependency's full licence text
ships inside its own package under node_modules, and inside the application
bundle where the dependency is bundled.

--------------------------------------------------------------------------------
Codicons
--------------------------------------------------------------------------------
Tortie's interface icons are the Codicon set from Microsoft.

  Icons are licensed under CC BY 4.0: https://creativecommons.org/licenses/by/4.0/
  Source code in that package is licensed under the MIT Licence.

CC BY 4.0 requires attribution, which is the reason this entry exists and the
reason the same credit appears in the application's About panel.

--------------------------------------------------------------------------------
Material Icon Theme
--------------------------------------------------------------------------------
Tortie's Explorer file icons are a curated subset of the Material Icon Theme.
The subset is extracted at build time by src/renderer/icons/generate-file-icons.mjs
into src/renderer/icons/file-icons.generated.ts, so that artwork ships inside
the application bundle rather than as a package of its own.

The MIT Licence requires that the notice above ship with the artwork, which is

Code copied from Visual Studio Code
--------------------------------------------------------------------------------
Two files contain algorithms copied or adapted from microsoft/vscode rather than
reimplemented, which is deliberate under the project rule to assemble rather than
reinvent.

Code copied from D3
--------------------------------------------------------------------------------
Two files contain algorithms copied from Mike Bostock's D3 rather than
reimplemented, vendored under the same assemble-rather-than-reinvent rule as
the VS Code extracts above. No d3 package ships in the application; only these
two transcriptions do.

Bundled fonts
--------------------------------------------------------------------------------
Tortie bundles two monospace families and offers them in Settings, Appearance,
Font. Neither is the default. The System preset ships no font bytes and draws
Menlo, which is already on the Mac. Four files ship, being the regular and the
bold member of each family.

  src/renderer/assets/fonts/JetBrainsMono-Regular.woff2       92,164 bytes
  src/renderer/assets/fonts/JetBrainsMono-Bold.woff2          94,588 bytes
  src/renderer/assets/fonts/SourceCodePro-Regular.otf.woff2   76,348 bytes
  src/renderer/assets/fonts/SourceCodePro-Bold.otf.woff2      77,372 bytes

Both families are licensed under the SIL Open Font License, Version 1.1. The
full licence text follows once and covers both. Neither family is modified and
neither is renamed.

  -----------------------------------------------------------
  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.

Bundled binaries
--------------------------------------------------------------------------------
The macOS application bundle carries three executables whose source is not this
repository. Each one runs as its own process. None of them is loaded into a
Tortie process.

  ripgrep, through @vscode/ripgrep     Andrew Gallant, MIT or Unlicense
  specstory                            SpecStory, bundled under a pinned release
  tmux                                 Nicholas Marriott and contributors, ISC

The tmux copy is built from source at packaging time by build/build-tmux.mjs,
from the three tarballs pinned in build/tmux-release.json. libevent and utf8proc
are linked into it as static archives, so no library of theirs is installed or
shipped as a separate file. ncurses comes from the operating system and is not
bundled.

--------------------------------------------------------------------------------
tmux
--------------------------------------------------------------------------------
Tortie bundles tmux 3.7b and runs it as a separate process on a private socket.
It never reads the user's own tmux configuration and never touches their default
server.

  libevent's LICENSE file carries one more notice, an MIT licence from
  BitTorrent, Inc. for the Windows timer code that came from libutp. This
  build is macOS only and does not compile that code, so the notice is named
  here and its text is not reproduced.

--------------------------------------------------------------------------------
utf8proc
--------------------------------------------------------------------------------
utf8proc 2.10.0 is linked into the bundled tmux as a static archive. It gives
tmux correct character widths, which Apple's own tables no longer provide.
