+  #     ignored in update mode.
+  #   - Manifest.lock: A file contained in the Pods folder that keeps track of
+  #     the pods installed in the local machine. This files is used once the

+  #     is already installed. This file is not intended to be kept under source

-
-    # Specifies a dependency of the project.
-    #
-    # A dependency requirement is defined by the name of the Pod and _optionally_
-    # a list of version requirements.
-    #
-    #
-    # When starting out with a project it is likely that you will want to use the
-    # latest version of a Pod. If this is the case, simply omit the version
-    # requirements.
-    #
-    #   pod 'SSZipArchive'
-    #
-    #
-    # Later on in the project you may want to freeze to a specific version of a
-    # Pod, in which case you can specify that version number.
-    #
-    #   pod 'Objection', '0.9'
-    #
-    #
-    # Besides no version, or a specific one, it is also possible to use operators:
-    #
-    # * `> 0.1`    Any version higher than 0.1
-    # * `>= 0.1`   Version 0.1 and any higher version
-    # * `< 0.1`    Any version lower than 0.1
-    # * `<= 0.1`   Version 0.1 and any lower version
-    # * `~> 0.1.2` Version 0.1.2 and the versions upto 0.2, not including 0.2
-    #
-    # A list of version requirements can be specified for even more fine
-    # grained control.
-    #
-    #
-    # For more information, regarding versioning policy, see:
-    #
-    # * http://semver.org
-    # * http://docs.rubygems.org/read/chapter/7
-    #
-    #
-    # Finally, instead of a version, you can specify the `:head` flag. This will
-    # use the pod’s latest version spec version, but force the download of the
-    # ‘bleeding edge’ version. Use this with caution, as the spec might not be
-    # compatible anymore.
-    #
-    #
-    # ## Dependency on a library, outside those available in a spec repo.
-    #
-    # ### From a podspec in the root of a library repo.
-    #
-    # Sometimes you may want to use the bleeding edge version of a Pod. Or a
-    # specific revision. If this is the case, you can specify that with your
-    # pod declaration.
-    #
-    #
-    # To use the `master` branch of the repo:
-    #
-    #   pod 'TTTFormatterKit', :git => 'https://github.com/gowalla/AFNetworking.git'
-    #
-    #
-    # Or specify a commit:
-    #
-    #   pod 'TTTFormatterKit', :git => 'https://github.com/gowalla/AFNetworking.git', :commit => '082f8319af'
-    #
-    #
-    # It is important to note, though, that this means that the version will
-    # have to satisfy any other dependencies on the Pod by other Pods.
-    #
-    #
-    # The `podspec` file is expected to be in the root of the repo, if this
-    # library does not have a `podspec` file in its repo yet, you will have to
-    # use one of the approaches outlined in the sections below.
-    #
-    #
-    # ### From a podspec outside a spec repo, for a library without podspec.
-    #
-    # If a podspec is available from another source outside of the library’s
-    # repo. Consider, for instance, a podpsec available via HTTP:
-    #
-    #   pod 'JSONKit', :podspec => 'https://raw.github.com/gist/1346394/1d26570f68ca27377a27430c65841a0880395d72/JSONKit.podspec'
-    #
-    #
-    # ### For a library without any available podspec
-    #
-    # Finally, if no living soul has created a podspec, for the library you want
-    # to use, yet, you will have to specify the library yourself.
-    #
-    #
-    # When you omit arguments and pass a block to `pod`, an instance of
-    # Pod::Specification is yielded to the block. This is the same class which
-    # is normally used to specify a Pod.
-    #
-    # ```
-    #   pod do |spec|
-    #     spec.name         = 'JSONKit'
-    #     spec.version      = '1.4'
-    #     spec.source       = { :git => 'https://github.com/johnezang/JSONKit.git', :tag => 'v1.4' }
-    #     spec.source_files = 'JSONKit.*'
-    #   end
-    # ```
-    #
-    #
-    # For more info on the definition of a Pod::Specification see:
