Apache Buildr (attic-buildr)
Category: retired, build-management
Programming language: Ruby
We wanted something that's simple and intuitive to use, so we only need to tell it what to do, and it takes care of the rest.  But also something we can easily extend for those one-off tasks, with a language that's a joy to use.
Maintainer: Apache Buildr PMC
Release: 1.5.5 (2017-12-06)
