-- * Creates the route datatype ~sitearg~Route. Every valid URL in your

-- type instance Route ~sitearg~ = ~sitearg~Route

-- mkYesodDispatch

-- ~sitearg~. Creating that instance requires all of the handler functions

-- for our application to be in scope. However, the handler functions
|
|
-- usually require access to the ~sitearg~Route datatype. Therefore, we
|
|
-- split these actions into two functions and place them in separate files.
