 ** Description
 
 This script provides a message code that allows you to change the face that
 will be displayed in the message box. This allows you to display different
 faces in the middle of a message.
 
 The message code is customizable so you can choose what code you want to use
 in case of conflicts with other scripts.
 
 This script can be used in conjunction with other scripts that treat
 certain face names in a special way. For example, you can use
 Placeholder Graphics to draw faces based on certain actors or party members.
 
--------------------------------------------------------------------------------
 ** Installation
 
 In the script editor, place this script below Materials and above Main

--------------------------------------------------------------------------------
 ** Usage
 
 The message code takes a name, which is the name of the face image to use.
 It also takes an index, which is the index of the face on the image.
 
 In the configuration, you choose the code and delimiter that you want to use
 for the message code. The delimiter is what separates the name from the index.
   
 By default, the code is MF and the delimiter is the comma (,).
 Use the message code
 
   \MF[name,index]
   
 To change the face that is shown in the message box.
 
--------------------------------------------------------------------------------
 ** Examples
 
 To change the face to the first face in the face sheet, use the code
 
 \MF[actor1,1]
 
 To change to the second face of the same sheet, use
 
 \MF[actor1,2]
