   - initial release
--------------------------------------------------------------------------------   
 ** Terms of Use
 * Free to use in non-commercial projects
 * Contact me for commercial use
 * No real support. The script is provided as-is
 * Will do bug fixes, but no compatibility patches
 * Features may be requested but no guarantees, especially if it is non-trivial

 ** Description
 
 This script allows you to setup event graphics based on party member
 formation. This is useful for setting up cut-scenes based on who is
 in your party.
 
--------------------------------------------------------------------------------
 ** Usage
 
 This script uses placeholder images.
 The name of the images follow this format:
 
    party#
    
 Where # is an integer that represents in the party. For example,
 
 "party1" would be the graphic of the first member in the party,
 "party2" would be the graphic of the second member in the party.
 
 Face images should be placed in the "Faces" folder, while character images
 should be placed in the "Characters" folder.
