Installing tmux 2.2

Problem:
How to install tmux 2.2 from source. (I am installing this on a vagrant box running Ubuntu 14.0).

Solution:
The read me works. Installing from the git version did not work for me.

1. Check the current version of tmux if installed. Remove it.

$ tmux -V
1.8
$ sudo apt-get remove tmux

2. Install the dependencies.

$ sudo apt-get install libevent-dev
$ sudo apt-get install ncurses-dev

3. Download and install tmux

$ cd ~
$ wget https://github.com/tmux/tmux/releases/download/2.2/tmux-2.2.tar.gz
$ tar -zxf tmux-2.2.tar.gz
$ cd tmux-2.2
$ ./configure && make

4. Create a symlink to new version of tmux

$ sudo ln -s /home/vagrant/tmux-2.2/tmux /usr/local/bin/tmux

5. Confirm that you now have the new version of tmux.

$ tmux -V
2.2

Alternatively:
You could use this script. (I have not tried it for 2.2 but I am guessing that it would work)
