# <tt>require "highline/import"</tt> adds shortcut methods to Kernel, making
# agree(), ask(), choose() and say() globally available. This is handy for
# quick and dirty input and output. These methods use the HighLine object in
# the global variable <tt>$terminal</tt>, which is initialized to used
# <tt>$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.
