 You have some examples in lib/*. For example

   if File::exist? file and not File::readable? file

 must be written

   if File::exist?(file) && ! File::readable?(file)

 to do the same.

   destdir = CONFIG["prefix"].scan(drive)[0] and !destdir.empty?

 must be written

  (destdir = CONFIG["prefix"].scan(drive)[0]) && !destdir.empty?
