   made by: Silverwind (Metaclaw)
-----------------------------------------------------------------------


 Instructions:

 1) To show some text above an event, add a script command, saying:
    text = "place your text here"
    popup(text)

 2) To show an icon in the popup, add a script command, saying:
    text = "place your text here" *
    icon = "the icon's name" **
    popup(text, icon)

   Notes:
   *  To show only an icon, set the text to ""
   ** The icon-name should not include ".png", ".jpg" etc.
      Please use "my_icon" instead of "my_icon.png"
