SW-Devs: do you use VERSION files?

[MBaas]

...and how do you update them?

I'm asking because I'm a victim myself and committed updated code without updating VERSION at the same time one too many times - so I finally developed a tool to deal with it. And before going public, I wanted to collect a bit of feedback from a group of friends So if you're interested, please have a look and lemme know what you think!
