# Introduction:
#   This is a small, very basic script I wrote a while back, but never released.
#   It allows for you to use the same type of commands you can use in event
#   "Show Message" commands, but within the descriptions of Weapons, Armors, and
#   Items. Review the commands below, they will be substituted in the actual
#   text to display the respective value.
#
# Commands:
#   \v[ID]  = Replaces with value of game variable with ID
#   \n[ID]  = Replaces with name of actor that has ID
#   \sw[ID] = Replaces with value of switch withg ID  (ON/OFF)
#   \g      = Replaces with amount of gold party has
#   \st     = Replaces with step count
#
# Author's Notes:
#   I can add more at request. Only values that are global to the RTP scripts
#   and cannot be easily accessed will be added to the script, though I can
#   still give someone a one line of code they can add themselves for custom
#   commands.
