A rebar3 plugin for auto running tasks on source file change.

Add the plugin to your rebar config, since it is a developer tool and not necessary for building any project you work on I put it in ~/config/.rebar3/rebar.config:
{plugins, [rebar3_auto]}.
Then just call your plugin directly in an existing application:
$ rebar3 auto
