REDISTRIBUTION
--------------

This binary distribution contains the below components. Components listed under
the "required" section must be redistributed with all applications using CEF.
Components listed under the "optional" section may be excluded if the related
features will not be used.

Applications using CEF on OS X must follow a specific app bundle structure.
Replace "cefclient" in the below example with your application name.

The "Chromium Embedded Framework.framework" is an unversioned framework that
contains CEF binaries and resources. Executables (cefclient, cefclient Helper,
etc) must load this framework dynamically at runtime instead of linking it
directly. See the documentation in include/wrapper/cef_library_loader.h for
more information.

The "cefclient Helper" app is used for executing separate processes (renderer,
plugin, etc) with different characteristics. It needs to have a separate app
bundle and Info.plist file so that, among other things, it doesn’t show dock
icons.

Required components:

The following components are required. CEF will not function without them.

* CEF core library.
  * Chromium Embedded Framework.framework/Chromium Embedded Framework

* Unicode support data.
  * Chromium Embedded Framework.framework/Resources/icudtl.dat

* V8 snapshot data.
  * Chromium Embedded Framework.framework/Resources/natives_blob.bin
  * Chromium Embedded Framework.framework/Resources/snapshot_blob.bin
  * Chromium Embedded Framework.framework/Resources/v8_context_snapshot.bin

Optional components:

The following components are optional. If they are missing CEF will continue to
run but any related functionality may become broken or disabled.

* Localized resources.
  Locale file loading can be disabled completely using
  CefSettings.pack_loading_disabled.

  * Chromium Embedded Framework.framework/Resources/*.lproj/
    Directory containing localized resources used by CEF, Chromium and Blink. A
    .pak file is loaded from this directory based on the CefSettings.locale
    value. Only configured locales need to be distributed. If no locale is
    configured the default locale of "en" will be used. Without these files
    arbitrary Web components may display incorrectly.

* Other resources.
  Pack file loading can be disabled completely using
  CefSettings.pack_loading_disabled.

  * Chromium Embedded Framework.framework/Resources/cef.pak
  * Chromium Embedded Framework.framework/Resources/cef_100_percent.pak
  * Chromium Embedded Framework.framework/Resources/cef_200_percent.pak
    These files contain non-localized resources used by CEF, Chromium and Blink.
    Without these files arbitrary Web components may display incorrectly.

  * Chromium Embedded Framework.framework/Resources/cef_extensions.pak
    This file contains non-localized resources required for extension loading.
    Pass the `--disable-extensions` command-line flag to disable use of this
    file. Without this file components that depend on the extension system,
    such as the PDF viewer, will not function.

  * Chromium Embedded Framework.framework/Resources/devtools_resources.pak
    This file contains non-localized resources required for Chrome Developer
    Tools. Without this file Chrome Developer Tools will not function.

* Angle support.
  * Chromium Embedded Framework.framework/Libraries/libEGL.dylib
  * Chromium Embedded Framework.framework/Libraries/libGLESv2.dylib
  Without these files HTML5 accelerated content like 2D canvas, 3D CSS and WebGL
  will not function.

* SwiftShader support.
  * Chromium Embedded Framework.framework/Libraries/libswiftshader_libEGL.dylib
  * Chromium Embedded Framework.framework/Libraries/libswiftshader_libGLESv2.dylib
  Without these files WebGL will not function in software-only mode when the GPU
  is not available or disabled.
