TortoiseHg is a graphical frontend for the Mercurial distributed revision control system. It integrates with the system’s file browser and provides context menu entries to manipulate files/folders under revision control. For example, users can right-click on a managed folder and select context menu entries to pull new changes from upstream sources, commit their local modifications, push their changes upstream, and more. Using Mercurial’s ‘foreign VCS system’ integrations, users can interact not just with Mercurial repositories, but also Perforce, Subversion, and Git repositories as well. The Quick Start Guide in the documentation provides a brief primer to get users up and running while the TortoiseHg in daily use section presents a detailed reference for common operations. In the Downloads section of the site, users can locate installers for Windows, macOS, and Linux systems.
