//Copy to Object(s) v4.5 -- CS,CS2
// "Multiple-object-replacement" hack by Iain Henderson
// iain@addition.com.au
//>=--------------------------------------
// User selects two (or more) objects:
// This script copies the top most object to the position and size of 
// all other selected objects.
//
//Version 2 update: now adjusts stroke based on difference in area.
//Version 3 update: now accepts multiple targets (Thanks Iain)
//Version 4 update: Deselects everything but source object 
//  --this makes it easy to delete the source object if you wish,
//  -- also this makes the older "Replace-Object" script obsolete.
// now allows user to choose whether to resize to target. (copies are centered to target.)
