-// SwapToP2pMultiaddrs is a function to make the transition from /ipfs/...
-// multiaddrs to /p2p/... multiaddrs easier
-// The first stage of the rollout is to ship this package to all users so
-// that all users of multiaddr can parse both /ipfs/ and /p2p/ multiaddrs
-// as the same code (P_P2P). During this stage of the rollout, all addresses
-// with P_P2P will continue printing as /ipfs/, so that older clients without
-// the new parsing code won't break.
-// Once the network has adopted the new parsing code broadly enough, users of
-// multiaddr can add a call to this method to an init function in their codebase.
-// This will cause any P_P2P multiaddr to print out as /p2p/ instead of /ipfs/.
-// Note that the binary serialization of this multiaddr does not change at any
-// point. This means that this code is not a breaking network change at any point
-//
-// DEPRECATED: this is now the default
