Creating group 'rvm'

Installing RVM to /usr/local/rvm/

Installation of RVM in /usr/local/rvm/ is almost complete:

  * First you need to add all users that will be using rvm to 'rvm' group,

    and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.

  * To start using RVM you need to run `source /etc/profile.d/rvm.sh`

    in all your open shell windows, in rare cases you need to reopen all shell windows.

  * Please do NOT forget to add your users to the rvm group.

     The installer no longer auto-adds root or users to the rvm group. Admins must do this.

     Also, please note that group memberships are ONLY evaluated at login time.

     This means that users must log out then back in before group membership takes effect!

Thanks for installing RVM [0m
