 /**
  * Call the init function of each paraslash receiver.
+ *
+ * Receivers employ the user_data feature of the lopsub library: Each receiver
+ * of the recv_cmd suite defines a struct receiver as its user data.
+ * recv_init() obtains a pointer to this structure by calling lls_user_data().
+ * If the receiver has an init function (i.e., if ->init is not NULL), ->init()
+ * is called to initialize the receiver.
