# File: Spinach.pm
#
# Purpose: Trivial game engine with a twist. Game is played in rounds. Each
# round players choose a category of questions. Then a random question from
# that category is shown. All players then privately submit a "lie" to the
# bot. Then all "lies" are revealed along with the true answer. Players
# gain points every time another player picks their lie. Very fun!
