Committer
Look up committer in Wiktionary, the free dictionary.
A committer is an individual who is permitted to modify the source code of a software project, that will be used in the project's official releases. 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, such as triaging issues or organizing events. Typically, an author submits a software patch containing changes and a committer integrates the patch into the main code base of the project.
