dir-compare.rb in the package is a tool kit for comparing plural
directories. For example, the recursive copy command is:

  require "dir-compare"
  require "ftools"

  class Cp < DirPairWalker
    def file_file(s, t)
      File.cp(s, t)
    end
  
    def file_non(s, t)
      File.cp(s, t)
    end
  
    def dir_non(s, t)
      File.mkpath(t)
    end
  end
  
  source, target = ARGV
  visitor = Cp.new
  dc = DirCompare.new(visitor)
  dc.run(source, target)

And the following is the command "rm -r":

  require "dir-compare"
  require "ftools"
  
  class Rm_r < DirWalker
    def file(s)
      File.unlink(s)
    end
  
    def dir_out(s)
      Dir.unlink(s)
    end
  end
  
  rm = Rm_r.new
  dc = DirCompare.new(rm)
  path = ARGV.shift
  dc.run(path)

The class DirCompare may assume to be an extension of Find.
Thank you.
