module Pod
  # The sandbox provides support for the directory that CocoaPods uses for an
  # installation. In this directory the Pods projects, the support files and
  # the sources of the Pods are stored.
  #
  # CocoaPods assumes to have control of the sandbox.
  #
  # Once completed the sandbox will have the following file structure:
  #
  #     Pods
  #     |
  #     +-- Headers
  #     |   +-- Private
  #     |   |   +-- [Pod Name]
  #     |   +-- Public
  #     |       +-- [Pod Name]
  #     |
  #     +-- Local Podspecs
  #     |   +-- External Sources
  #     |   +-- Normal Sources
  #     |
  #     +-- Target Support Files
  #     |   +-- [Target Name]
  #     |       +-- Pods-acknowledgements.markdown
  #     |       +-- Pods-acknowledgements.plist
  #     |       +-- Pods-dummy.m
