+ * before opping a user, deopping a user, kicking a user, etc.
+ * There are several values for access_type which indicate for what reason access is being checked.
+ * These are:<br><br>
+ * AC_KICK (0) - A user is being kicked<br>
+ * AC_DEOP (1) - a user is being deopped<br>
+ * AC_OP (2) - a user is being opped<br>
+ * AC_VOICE (3) - a user is being voiced<br>
+ * AC_DEVOICE (4) - a user is being devoiced<br>
+ * AC_HALFOP (5) - a user is being halfopped<br>
+ * AC_DEHALFOP (6) - a user is being dehalfopped<br>
+ * AC_INVITE (7) - a user is being invited<br>
+ * AC_GENERAL_MODE (8) - a user channel mode is being changed<br><br>
+ * Upon returning from your function you must return either ACR_DEFAULT, to indicate the module wishes
+ * to do nothing, or ACR_DENY where approprate to deny the action, and ACR_ALLOW where appropriate to allow
+ * the action. Please note that in the case of some access checks (such as AC_GENERAL_MODE) access may be
+ * denied 'upstream' causing other checks such as AC_DEOP to not be reached. Be very careful with use of the
+ * AC_GENERAL_MODE type, as it may inadvertently override the behaviour of other modules. When the access_type
+ * is AC_GENERAL_MODE, the destination of the mode will be NULL (as it has not yet been determined).
