+ * This class provides an easy way to link commands to inputs.
+ *
+ * It is very easy to link a polled input to a command.  For instance, you could
+ * link the trigger button of a joystick to a "score" command or an encoder reaching
+ * a particular value.
+ *
+ * It is encouraged that teams write a subclass of Trigger if they want to have
+ * something unusual (for instance, if they want to react to the user holding
+ * a button while the robot is reading a certain sensor input).  For this, they
+ * only have to write the {@link Trigger#Get()} method to get the full functionality
+ * of the Trigger class.
