+  #
+  #  Specify the authors of the library, with email addresses. Email addresses

+  #  accepts just a name if you'd rather not provide an email address.

+  # ――― 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.

+  #
+  #  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.

+  #
+  #  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.
