  args.pop if Hash===args.last
  cmd = args.join(' ')
  if RUBY_PLATFORM =~ /win32|mingw|mswin/
    cmd.gsub!('/','\\') # Replace / with \\
    cmd.gsub!(/^cd /,'cd /D ') # Replace cd with cd /D
    cmd.gsub!(/&& cd /,'&& cd /D ') # Replace cd with cd /D
    logger.trace "executing locally: #{cmd}"
    Kernel.system cmd

    logger.trace "executing locally: #{cmd}"
    Kernel.system cmd
