+This is an experimental framework for comparing version control merging algorithms.
+It runs each merge tool on 6045 real-world merges.
+It classifies each merge as a conflict, a correct merge, or an incorrect merge.
+It uses each project's test suite to determine whether the merge was correct,
+and it penalizes merge tools for creating incorrect merges.
+
+The paper [Evaluation of Version Control Merge
+Tools](https://homes.cs.washington.edu/~mernst/pubs/merge-evaluation-ase2024-abstract.html)
+evaluates 16 merge algorithms, including
+[Hires-Merge](https://github.com/paulaltin/git-hires-merge),
+[IntelliMerge](https://github.com/Symbolk/IntelliMerge),
+[Plume-lib Merging](https://github.com/plume-lib/merging), and
+[Spork](https://github.com/ASSERT-KTH/spork).
+Since then, the framework has been expanded to evaluate newer algorithms,
+such as
+[Mergiraf](https://mergiraf.org/).
