open3.rb

open3.rb: Spawn a program like popen, but with stderr, too. You might also want to use this if you want to bypass the shell. (By passing multiple args, which IO#popen does not allow)

Usage:

      require "open3"

     stdin, stdout, stderr = Open3.popen3('nroff -man')
 or
      include Open3
     stdin, stdout, stderr = popen3('nroff -man')
