basho/rebar
This system is a build tool and dependency manager for Erlang and related languages, designed to compile, test, and package software projects. It manages complex dependency resolution, including transitive dependencies and custom configurations, while supporting various compilation targets like Erlang, LFE, and ABNF grammars. The tool also facilitates release generation, Common Test integration, and project scaffolding through templates.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit cd55176009 — the exact code this score is about.
- Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
