-- | This embeds just a single file; it embeds the source code file 
-- \"sample-embed.hs\" from the current directory so when you compile,
-- the sample-embed.hs file must be in the current directory.
--
-- Try toggling the development argument to 'mkEmbeddedStatic'. When the
-- development argument is true the file \"sample-embed.hs\" is reloaded
-- from disk on every request (try changing it after you start the server).
-- When development is false, the contents are embedded and the sample-embed.hs
-- file does not even need to be present during runtime.
