module Sym

  # The {Sym::App} Module is responsible for handing user input and executing commands.
  # Central class in this module is the {Sym::App::CLI} class. However, it is
  # recommended that ruby integration with the {Sym::App} module functionality
  # is done via the {Sym::Application} class.
  #
  # Methods in this module are responsible for reporting errors and
  # maintaining the future exit code class-global variable.
  #
  # It also contains several helpers that enable some additional functionality
  # on Mac OS-X (such as using KeyChain for storing encryption keys).
