### END INIT INFO

## instead of using the installed script at /usr/local/ruby/bin/thin which
## fires up thin without bundler, this will cd into each site found in
## /etc/thin and run 'bundle exec thin'. Not pretty, but it is necessary to
## launch thin with bundler to avoid gem versioning conflicts
