# We normally write our documents from top to bottom and it is no different with
# Prawn. Even if the origin is on the bottom left corner we still fill the page
# from the top to the bottom. In other words the cursor for inserting content
# starts on the top of the page.
#
# Most of the functions that insert content on the page will start at the
# current cursor position and proceed to the bottom of the page.
#
# The following snippet shows how the cursor behaves when we add some text to
# the page and demonstrates some of the helpers to manage the cursor position.
# The <code>cursor</code> method returns the current cursor position.
#
require File.expand_path(File.join(File.dirname(__FILE__),
%w[.. example_helper]))
