Installing on ArchLinux with

sudo pip install shutit # defaults to pip3

and then running

shutit skeleton

results in the following error: NameError: name 'raw_input' is not defined

I then installed with pip2.7 and it’s working now, but I was unable to see this anywhere other than your setup.py file. Shouldn’t it be documented somewhere more visible, eg. the Readme or your website? I almost gave up experimenting with this tool, maybe other people would too.
