People commented so nicely on my first build tool FBU that I decided to push it to the Elixir package manager Hex.pm. I renamed it, though, since people pointed out that it could be used to build anything, not just the front end. So now it’s called (still unimaginatively) MBU: Mix Build Utilities.

EDIT 2017-04-04: I have since renamed the project to MBU: Mix Build Utilities and published it on Hex.pm: hex.pm/packages/mbu. I have edited the links and code examples in this post to reflect that.
tl;dr I wrote my own build tool using Elixir’s Mix: Nicd/mbu.
