TortoiseHg is a Windows shell extension and a series of applications for the Mercurial distributed revision control system. It also includes a Gnome/Nautilus extension and a CLI wrapper application so the TortoiseHg tools can be used on non-Windows platforms.
Note that Mercurial on Windows is known to be incompatible with Avira Antivir Personal and AVG free.
