RVM is my preferred way of setting up ruby projects. It is very easy to have multiple gemsets, multiple versions, update your current ruby versions etc. I wanted to automate the procedure of selecting gemset per project so after a little search, I found a way to have an auto-select way.
Just create two files, the .ruby-version and .ruby-gemset inside your project-folder and set the ruby version and your gemset name. For example, if you put these specific two files from the repository, inside your project-folder, it will automatically change your rvm ruby version to ruby-2.0.0-p353 and gemset to crowdunding.
Do not forget to add them in your .gitignore, otherwise everyone with RVM will have a fit! Now when you navigate in this folder inside your console, your version and gemset will change automatically. Thanks Eleni for the tip!
