Download the latest version at the project's homepage.

To build impact yourself, you will need the following:

1. Scala 2.11.x (I used 2.11.5)
2. SBT 0.13.x (I used 0.13.6)
3. JDK 8

Once these are all installed, cd into the root directory and run the following in your terminal:

>> chmod +x build.sh
>> ./build.sh

If everything works correctly, you should see impact.zip in dist/.
