// Name: rd_CompRenamer
// Version: 3.0
// 
// Description:
// This script displays a palette with controls for renaming the 
// selected compositions in the Project panel. You can use this 
// script to, for example, remove the " Comp #" suffix (or 
// localized equivalent in German and French versions of After 
// Effects) added to new compositions whose footage was 
// previously dragged to the New Composition button.
// 
// Notes: Expressions that refer to the existing composition 
// names are not updated, so it's best to use this script after 
// creating a composition.
// 
// Note: This version of the script requires After Effects CS5 
// or later. It can be used as a dockable panel by placing the 
// script in a ScriptUI Panels subfolder of the Scripts folder, 
// and then choosing this script from the Window menu.
// 
// Legal stuff:
// This script is provided "as is," without warranty of any kind, expressed
// or implied. In no event shall the author be held liable for any damages 
// arising in any way from the use of this script.
// 
// In other words, I'm just trying to share knowledge with and help out my
// fellow AE script heads, so don't blame me if my code doesn't rate. :-)
