+  Following popular libraries like Ruby's <https://capistranorb.com Capistrano>,
+  Hapistrano does the work of building the application
   with dependencies into a distinct folder, and then atomically moves
   a symlink to the latest complete build.
   .
   This allows for atomic switchovers to new application code after the
   build is complete. Rollback is even simpler, since Hapistrano can
   just point the `current` symlink to the previous release.
