Using capistrano 3.2.1 the old #{varname} syntax no longer worked, switched to using capistrano's fetch(...) in example file.
Swopped capistrano default methods into regular "#{method_name} type calls. Using fetch to retrieve variables previously set using set.
Merge branch 'master' of github.com:platanus/capistrano3-nginx into usingfetch
Merge pull request #9 from jjabba/usingfetch
