This is the standard Play template (play 2.2.0) bundled with a helper class (playpackager.Packager) to write out static versions of the site.
Since this is a standard Play 2.x application, feel free to use all the built-in play console commands.
To package the site, use run-main playpackager.Packager. This will create a timestamp directory inside output, with a copy of everything inside public, and all the static HTML files specified by Application.mapping and Application.extraMaps.
