-// Package fd provides a simple API to pass file descriptors
-// between different OS processes.
-//
-// It can be useful if you want to inherit network connections
-// from another process without closing them.
-//
-// Example scenario:
-//
-//   1) Running server receives a "let's upgrade" message
-//   2) Server opens a Unix domain socket for the "upgrade"
-//   3) Server starts a new copy of itself and passes Unix domain socket name
-//   4) New copy starts reading for the socket
-//   5) Server sends its state over the socket, also sending the number
-//      of network connections to inherit, then it sends those connections
-//      using fd.Put()
-//   6) New copy reads the state and inherits connections using fd.Get(),
-//      checks that everything is OK and sends the "OK" message to the socket
-//   7) Server receives "OK" message and kills itself
