+This mod adds a farebox that emmits a mesecons signal whenever a payment is accepted.
+
+It also adds faregates that open when a payment is received and close
+when they receive a mesecons signal, i.e. from a pressure pad right
+behind them that verifies that the player has passed through the
+faregate.
