# <tt>require "highline/import"</tt> adds shortcut methods to Kernel, making
# {HighLine#agree}, {HighLine#ask}, {HighLine#choose} and {HighLine#say}
# globally available. This is handy for
# quick and dirty input and output. These methods use HighLine.default_instance
# which is initialized to use <tt>$stdin</tt> and <tt>$stdout</tt> (you are free
# to change this).
# Otherwise, these methods are identical to their {HighLine} counterparts,
# see that class for detailed explanations.
