Programming Contest: Efficient Editor Usage

Fred (a.k.a. The POTM-MASTER) writes "Anyone can write editors, but it's surprisingly hard to write a program to USE an editor. This latest Programming challenge asks you to write a program that will change one block of text into another using a simple set of 'vim-like' editor commands." (Find the details here.) "Deadline is May 31, 2005 so you've got plenty of time. The POTM is the 'Programmer Of The Month' contest - newly revived and active with about 1000 folks registered for the forums. It is completely for fun - unsponsored and prize-less except for the fame!"
