Tortoise HG lets you access the Mercurial version control system from within Windows
Explorer letting you do your work with right clicks. HG is the atomic symbol for
Mercury, named after the Latin word for mercury hydrargyrum (water-silver). So much of Tortoise HG simply duplicates Windows Explorer (My
Computer) functions. Tortoise HG does them in the exact same way in the exact same
places you are used to.
