// Package Profiles, and its children, provide implementations of the
// v23.Profile function. These implementations should import all of the
// packages that they require to implement Profile-specific functionality.
//
// The taxonomy used to organise Profiles may be arbitrary and the directory
// structure used here is just one convention for how to do so. This directory
// structure reflects the generality of a Profile at any given depth in the
// hierarchy, with higher levels of the directory structure being more
// generic and lower levels more specific.
//
// Profiles register themselves by calling v.io/v23/rt.RegisterProfile in their
// init function and are hence are chosen by importing them into an
// applications main package. It is an error to import more than one profile,
// and the registration mechanism will panic if this is attempted.
// Commonly used functionality and pre-canned profiles are in profiles/internal.
//
// This top level directory contains a 'generic' Profile and utility routines
// used by other Profiles. It should be imported whenever possible and
// particularly by tests.
//
// The 'roaming' Profile adds operating system support for varied network
// configurations and in particular dhcp. It should be used by any application
// that may 'roam' or any may be behind a 1-1 NAT. The 'static' profile
// does not provide dhcp support, but is otherwise like the roaming profile.
