What does 'rc' stand for in all those .*rc files anyway? Why not Ronald Chase?

ronaldchase.rb

#!/usr/bin/env ruby

require 'fileutils'

path = File.expand_path('~/.*rc')
Dir[path].each do |file|
  next unless File.file?(file)
  destination = file.gsub(/rc$/, 'ronaldchase')
  puts "#{file} -> #{destination}"
  FileUtils.ln_s(file, destination)
end
