+Sporks are a mechanism by which updated code is released to the network, but
+not immediately made active (or “enforced”). Enforcement of the updated code
+can be activated remotely. Should problems arise, the code can be deactivated
+in the same manner, without the need for a network-wide rollback or client update.
+
+The `spork` message tells the receiving peer the status of the spork defined by
+the SporkID field.
