# = 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.
