Installing Mono, F# and NUnit

These instructions allow you to install Mono and F# on Ubuntu 12.04.

Install the mono related tools in your system. At the command line type:
```
sudo apt-get install mono-dmcs mono-devel mono-utils
```
Create and move to the directory where you want to install F#. For example, in your $HOME directory, type the following at the command line:
```
mkdir Programs

cd Programs
```
Download the fsharp2.0.tgz file into the Programs directory. Extract the tarball file. At the command line type:
```
tar xvzf fsharp2.0.tgz
```
Move to the fsharp directory and run the installation script. Type at the command line:
```
cd fsharp

sudo ./install.sh
```
Edit the .bashrc file. At the command line type:
```
gedit $HOME/.bashrc
```
Go to very end of the file and add the following lines:
```
export FSHARP_HOME=$HOME/Programs/fsharp
export PATH=$FSHARP_HOME/bin:$PATH
```
Save the file.
Make sure your terminal window runs as a login shell. In the terminal's main menu select Edit/Profile Preferences. Select the Title and Command tab, and tick the "Run command as login shell" check-box.

Close all open terminal windows and open a new one.

Verify that F# was installed correctly. Type at the command line:
