Socket address convenience functions for Go. go-sockaddr is a convenience
library that makes doing the right thing with IP addresses easy. go-sockaddr is
loosely modeled after the UNIX sockaddr_t and creates a union of the family of
sockaddr_t types (see below for an ascii diagram). Library documentation is
available at https://godoc.org/github.com/hashicorp/go-sockaddr. The primary
intent of the library was to make it possible to define heuristics for selecting
the correct IP addresses when a configuration is evaluated at runtime. See the
docs, template package, tests, and CLI utility for details and hints as to how
to use this library.
