These are some of the server engines built by the Revel team.
In order to use an engine you must import the module and set
the configuration option server.engine equal to the engine you want.
You may define your own engine by implementing revel.ServerEngine and
registering it with revel in an init
function revel.RegisterServerEngine(NAME, <function to return your server instance>). See
revel.GoHttpServer for an example
app.conf
server.engine Defaults to go. Specify the engine you wish to use
