 `./wait-for` is a script designed to synchronize services like docker containers. It is [sh](https://en.wikipedia.org/wiki/Bourne_shell) and [alpine](https://alpinelinux.org/) compatible. It was inspired by [vishnubob/wait-for-it](https://github.com/vishnubob/wait-for-it), but the core has been rewritten at [Eficode](http://eficode.com/) by [dsuni](https://github.com/dsuni) and [mrako](https://github.com/mrako).
 
 When using this tool, you only need to pick the `wait-for` file as part of your project.

-## Testing

-Ironically testing is done using [bats](https://github.com/sstephenson/bats), which on the other hand is depending on [bash](https://en.wikipedia.org/wiki/Bash_(Unix_shell)).
