Typometer

First, extract the .zip file and then the .jar file.
Enter the newly created folder and open a terminal at that location. (Should be <download location>/typometer-x.x.x)
Enter the following line in the terminal:

java com.pavelfatin.typometer.Application

Important: Use BASH instead of FISH, as the colors in FISH confuse the program.
