SLEX
slex is a simple binary that allows you to run a command on multiple hosts via SSH.
It is very similar to fabric except that it is written in Go so you don't have to
have python installed on your system and you don't have to write a script or
configuration files if you do not want to.

go get -u github.com/crosbymichael/slex
