+//===== Hercules Plugin ======================================
+//= Maximum Level Exp Gain
+//===== By: ==================================================
+//= Originally By AnnieRuru
+//= Modifed by Dastgir[Hercules]
+//===== Current Version: =====================================
+//= 1.3
+//===== Compatible With: ===================================== 
+//= Hercules 2017-06-21
+//===== Description: =========================================
+//= stop players from gaining exp after certain level
+//===== Topic ================================================
+//= http://herc.ws/board/topic/11587-maxlvexpgain/
+//===== Additional Comments: =================================
+//= this plugin DOES
+//= 1. stop players gain exp through killing monsters, mvp exp, or share party experience
+//= 2. allows to gain exp by *getexp script command or BaseExp++ / JobExp++
+//= 3. allows players to pay guild tax exp after they hit your capped level value
+//= 4. if your server has heal_exp, resurrection_exp or shop_exp enable,
+//=    they will stop gain exp from these action after they hit your cap level
+//= 5. if the player do SA_LEVELUP ( a random skill from Hocos-Pocus ) after the cap level, they can't gain exp, or pay guild tax using this skill
+//= ... it seems like SA_LEVELUP skill and guild->payexp hate each other ...
