This plugin originally started life as a shell script (lfetool -- there's even a T-shirt for it!), then it toyed with integrating with rebar (the original). Around that time, though, rebar3 was under initial development, and LFE took a chance on it as an early adopter. This lead to a whole series of LFE plugins, but after a few years momentum was lost.

Those early rebar3 efforts have been combined into a single plugin in this project, with many updates and using all the latest approaches developed in rebar3's now mature ecosystem.
