+      pasteurize, customized 2to3-based scripts that helps you to convert

+Instead, rely on programs to be in PATH, as gluster already

-        python-future is the missing compatibility layer between Python 2 and
-        Python 3. It allows you to use a single, clean Python 3.x-compatible
-        codebase to support both Python 2 and Python 3 with minimal overhead.
-
-        It provides future and past packages with backports and forward ports
-        of features from Python 3 and 2. It also comes with futurize and
-        pasteurize, customized 2to3-based scripts that helps you to convert
-        either Py2 or Py3 code easily to support both Python 2 and 3 in a
-        single clean Py3-style codebase, module by module.
