First: you need a Java runtime on your computer. Then, if not already done: download the application here and then execute in a terminal
java [-Xmx512m] -jar tint.jarThe parameter -Xmx is not neccessary, but sets the maximum memory consumed by Java. Here is is set to 512MB. If the application hangs, it could be neccessary to encrease the value (like -Xmx1024m). You can place the tint.jar file whereever you want, but then you have to provide the path, too, like
java [-Xmx512m] -jar /path/to/tint.jarYou can also put this command in a shell script called "tint" and then execute on command line just the tint command.
