MakeMKV is software to convert blu-ray and dvd to mkv, whilst it is in development it is currently free as shareware for Linux. As a consequence it updates every other month and you have to install and update it manually. You will occasionally need grab a new licence key for the shareware version which is avaiable from the MakeMKV forums. I started to write my own script to download, install and keep up to date MakeMKV. However, after getting my own script to work I found this far more elegant solution that I wanted to share. All kudos to Jeff Bower at ebower.com...
