+because it provides a process-less architecture.  Instead, Mint is based on a
+functional and immutable data structure that represents an HTTP connection.
+
+This data structure wraps a TCP or SSL socket.  This allows for more
+fine-tailored architectures where the developer is responsible for wrapping the
+connection struct, such as having one process handle multiple connections or
+having different kinds of processes handle connections.")
