9. About Revision Control.. is the process of managing multiple versions of a piece of information. In its simplest form, this is something that many people do by hand :- ◦ every time you modify a file, save it under a new name that contains a number, each one higher than the number of the preceding version. Examples :  GIT.  Mercurial.

13. Installing Mercurial on your system Linux : ◦ Debian :  apt-get install mercurial ◦ Fedora Core :  yum install mercurial ◦ OpenSUSE :  yum install mercurial ….

14. Installing Mercurial on your system.. Solaris : ◦ Sun FreeWare, at http://www.sunfreeware.com http://www.sunfreeware.com Windows : ◦ Mercurial for Windows at http://mercurial.berkwood.com http://mercurial.berkwood.com ◦ This package has no external dependencies; it “just works”.

15. Getting started ! To begin, we'll use the hg version command to find out whether Mercurial is actually installed properly. ◦ $ hg version Mercurial Distributed SCM (version -) Copyright (C) 2005-2008 Matt Mackall and others This is free software; see the source for copying conditions.
