    # = Apt Package Installer
    #
    # The Apt package installer uses the +apt-get+ command to install
    # packages. The apt installer has only one option which can be
    # modified which is the +dependencies_only+ option. When this is
    # set to true, the installer uses +build-dep+ instead of +install+
    # to only build the dependencies.
    # 
    # == Example Usage
    #
    # First, a simple installation of the magic_beans package:
    #
    #   package :magic_beans do
    #     description "Beans beans they're good for your heart..."
    #     apt 'magic_beans_package'
    #   end
    #
    # Second, only build the magic_beans dependencies:
    #
    #   package :magic_beans_depends do
    #     apt 'magic_beans_package' { dependencies_only true }
    #   end
    #
    # As you can see, setting options is as simple as creating a
    # block and calling the option as a method with the value as 
    # its parameter.
