# ▼ Updates
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# 2011.12.20 - Started Script and Finished.
# 
#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script allows for classes to be unlocked after a class reaches a certain
# level. Note that this script is made for the Class System script and not
# using the MAINTAIN_LEVELS feature. Requirements for unlocking a class can be
# multiple level requirements as well.
# 
#==============================================================================
# ▼ Instructions
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# To install this script, open up your script editor and copy/paste this script
# to an open slot below ▼ Materials/素材 but above ▼ Main. Remember to save.
# 
# -----------------------------------------------------------------------------
# Class Notetags - These notetags go in the class notebox in the database.
# -----------------------------------------------------------------------------
# <level unlock requirements>
#   class x: level y
#   class x: level y
# </level unlock requirements>
# Sets the requirements for unlocking that particular class. The unlocking of
# the class will require classes x to be at level y. Insert multiple of the
# strings in between the two opening and closing notetags to require all of the
# class levels to be met.
# 
#==============================================================================
# ▼ Compatibility
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script is made strictly for RPG Maker VX Ace. It is highly unlikely that
# it will run with RPG Maker VX without adjusting.
# 
# This script requires Yanfly Engine Ace - Class System v1.01+.
# 
#==============================================================================
# ▼ Editting anything past this point may potentially result in causing
# computer damage, incontinence, explosion of user's head, coma, death, and/or
# halitosis so edit at your own risk.
