It's definitely something only targeted to Ruby devs. If you use ruby, you know what RVM is.
To answer your question, RVM is a version manager for Ruby. http://rvm.io/
I assume that if you don't know (like me), you're not in the target audience of people willing to chip in to get the conversion done, but it still manages to frustrate me.
