content: ------------------------------------------------------------------------------
  -- | This module contains primitives and helper functions for handling
  -- requests with @Content-type: multipart/form-data@, i.e. HTML forms and file
  -- uploads.
  --
  -- Typically most users will want to use 'handleFileUploads', which writes
  -- uploaded files to a temporary directory before sending them on to a handler
  -- specified by the user.
  --
  -- Users who wish to handle their file uploads differently can use the
  -- lower-level interface called 'handleMultipart'. That function takes
  -- uploaded files and streams them to a consumer of the user's choosing.
  --
  -- Using these functions requires making \"policy\" decisions which Snap can't
  -- really make for users, such as \"what's the largest PDF file a user is
  -- allowed to upload?\" and \"should we read form inputs into the parameters
  -- mapping?\". Policy is specified on a \"global\" basis (using
  -- 'UploadPolicy'), and on a per-file basis (using 'PartUploadPolicy', which
  -- allows you to reject or limit the size of certain uploaded
  -- @Content-type@s).
  --
  -- Example usage:
  --
  -- @
  -- {-\# LANGUAGE OverloadedStrings #-}
  --
  -- module Main where
  --
  -- import qualified Data.ByteString.Char8 as B8
  -- import           Data.Functor          ((\<$>))

  -- import           Snap.Http.Server      (quickHttpServe)
  -- import           "Snap.Util.FileUploads"
  -- import           System.Posix          (FileOffset, fileSize, getFileStatus)

  --     \\\<\/form>\"
