## Description

Git Gutter is an Emacs editor extension that displays version control change indicators in the margin and supports incremental staging of diff hunks. It tracks file modifications and differences across multiple backends including Git, Mercurial, Subversion, and Bazaar, providing real-time visual feedback directly within the editing environment.

The extension renders custom visual glyphs to highlight added, modified, and deleted lines relative to a repository revision. It includes capabilities for cycling through changed blocks, viewing detailed diff summaries, and interactively staging individual change hunks without leaving the text editor. 

Operations are supported by background worker processes and configurable idle timers to keep visual indicators synchronized while maintaining interface responsiveness during disk operations. An abstracted version control adapter layer delegates backend-specific commands through a unified interface.
