# i am using in the project's folder a file named .config-rvm which contains on each line the branches that 
# we want for to have different gemsets. 
#The branches that are not in the fle will usee the project's gemset. 
# If you don't need this functionality you will not need to create the file .
#Please be careful that the branch name is escaped and only small letters and numbers are allowed. 
#So if you have a branch like
#feature/rails_upgrade_23   it will have to put like this "featurerailsupgrade23" inside the file.
