-  # This description is used to generate tags and improve search results.

-  #
-  #  Licensing your code is important. See http://choosealicense.com for more info.

-  #  Popular ones are 'MIT', 'BSD' and 'Apache License, Version 2.0'.

-  # ――― Author Metadata  ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
-  #
-  #  Specify the authors of the library, with email addresses. Email addresses
-  #  of the authors are extracted from the SCM log. E.g. $ git log. CocoaPods also
-  #  accepts just a name if you'd rather not provide an email address.

-  #  Specify a social_media_url where others can refer to, for example a twitter
-  #  profile URL.

-
-  # ――― Platform Specifics ――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
-  #

-
-  # ――― Source Location ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #

-  #  Specify the location from where the source should be retrieved.
-  #  Supports git, hg, bzr, svn and HTTP.

-
-
-  # ――― Source Code ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
-  #
-  #  CocoaPods is smart about how it includes source code. For source files
-  #  giving a folder will include any swift, h, m, mm, c & cpp files.
-  #  For header files it will include any header in the folder.
-  #  Not including the public_header_files will make all headers public.
-  #
-
-  #s.public_header_files  = "/*.h"
-
-  # s.public_header_files = "Classes/**/*.h"
-
-
-  # ――― Resources ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
-  #
-  #  A list of resources included with the Pod. These are copied into the
-  #  target bundle with a build phase script. Anything else will be cleaned.
-  #  You can preserve files from being cleaned, please don't preserve
-  #  non-essential files like tests, examples and documentation.
-  #
-
-  # s.resource  = "icon.png"
-  # s.resources = "Resources/*.png"
-
-  # s.preserve_paths = "FilesToSave", "MoreFilesToSave"
   s.preserve_paths = "Cronet.framework"
   s.public_header_files = "Cronet.framework/Headers/**/*{.h}"
-
-
-  # ――― Project Linking ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
-  #
-  #  Link your library with frameworks, or libraries. Libraries do not include
-  #  the lib prefix of their name.
-  #
-
-  # s.framework  = "SomeFramework"
-  # s.frameworks = "SomeFramework", "AnotherFramework"
-
-  # s.library   = "iconv"
-  # s.libraries = "iconv", "xml2"
-
-
-  # ――― Project Settings ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
-  #
-  #  If your library depends on compiler flags you can set them in the xcconfig hash
-  #  where they will only apply to your library. If you depend on other Podspecs
-  #  you can include multiple dependencies to ensure it works.
-
-  # s.requires_arc = true
-
-  # s.xcconfig = { "HEADER_SEARCH_PATHS" => "$(SDKROOT)/usr/include/libxml2" }
