def description # :nodoc:
    <<-EOF
The owner command lets you add and remove owners of a gem on a push
server (the default is https://rubygems.org).

The owner of a gem has the permission to push new versions, yank existing
versions or edit the HTML page of the gem.  Be careful of who you give push
permission to.
