# likewise require
# by Pat Nakajima
# because I've been drinking more than Jack Barnette
# and
# to annoy John Susser and Aaron Peterson
#
# use to require files relative to the current file:
#
# likewise do
#   require "foo"         # require current-dir/lib
#   require "lib/foo"     # require current-dir/lib/foo
