Comment 5 for bug 1377566

Thanks for the advice on the version code. Looking closer I can see now I missed this because I was working off of version 1.4, and master does include a cleaner more elegant solution.

If I wasn't focused on the file format I'd probably be trying to fix Pinta to include the command line arguments --help and --version that gnu always recommends, and it helps to have a properly abstracted version number there too. https://www.gnu.org/prep/standards/html_node/Command_002dLine-Interfaces.html
