Repeater – A tool which repeats commands

It repeats commands as quickly as it can. So it's not a cronjob manager.

Quite battletested on heavy devops tasks. The design is simple: every command is a subprocess spawned by in -n number of go routines. Then there's some extra fluff to tie the worker pattern together and deliver statistics.

Why not xargs? Ergonomics, and speed. Repeater is faster, see benchmarks.
