[3] To contribute source code to most large software projects, one must make modifications and then "commit" those changes to a central version control system, such as Git (or CVS).
In open-source software development, the committer role may be used to distinguish commit access, a specific type of responsibility, from other forms of contribution,[4] such as triaging issues or organizing events.
[7] The commit bit represents the permission to contribute to the shared code of a software project.
It can be resigned or may be removed due to inactivity in the project, as dormant committer accounts can represent security risks.
[9] Relatedly, committers are usually responsible for the review of patches submitted by members of the community for inclusion into the software.
