Debian Backporting

It is easy to install packages on Debian. All you have to do is "apt-get install package". But what if we would like to install a newer version package? For example, git-core version on Debian stable is 1.4.4. It is too old and does not have basic commands such as git config, init,... etc. We may install git from Debian Backports. It is a easier way than building from source for most people.
