I had this idea where there is just one command to install something (e.g. docker) on any machine, be it Ubuntu or Fedora or Mac, for development purposes. More information in the readme:
> you mean like a package manager? what's wrong with apt, brew etc
Yes, like a universal package manager, but only for quick and dirty dev environment setup. The problem with apt, brew etc is that brew is for Mac only, and APT is for debian-like distros only.
the script at https://get.docker.com/ is exactly what I was thinking of building. Thanks for the pointer. Now I can't think of anything for which Xin-like thing would be useful apart from Vagrant installation.
also there already is a command to install docker on any machine
curl -sSL https://get.docker.com/ | sh
and as a bonus:
