Mercurial <1> <2>
Mercurial is a free, distributed version control system. Mercurial is a command line program but graphical user interface (GUI) extensions are available. All of Mercurial's operations are invoked as arguments to its driver program hg, a reference to the chemical symbol of the element mercury.
TortoiseHg is a Mercurial's GUI. Tortoise also provides GUI for other version control systems such as TortoiseCVS for Concurrent Version System (CVS), TortoiseSVN for Subversion, and TortoiseGit for Git.

- hg merge: join different lines in the history graph.
- hg commit -m "merge": commit all changes and update the history graph.
- hg push: push out all changes from your repository into another one.
Here's other useful Mercurial commands:
