%description
RVM is the Ruby Version Manager (rvm). It manages Ruby interpreter environments
and switching between them.

This package is meant for use by multiple users maintaining a shared copy of
RVM. Users added to the '%{rvm_group}' group will be able to modify all aspects
of RVM. These users will also have their default umask changed to g+w (0022) to
ensure correct permissions for the shared RVM content.

RVM is activated for all logins by default. To disable remove 
%{_sysconfdir}/profile.d/rvm.sh and source rvm from each users shell.
