can do so by setting [Transport.TLSNextProto] (for clients) or
[Server.TLSNextProto] (for servers) to a non-nil, empty
map. Alternatively, the following GODEBUG settings are
currently supported:

	GODEBUG=http2client=0  # disable HTTP/2 client support
	GODEBUG=http2server=0  # disable HTTP/2 server support
	GODEBUG=http2debug=1   # enable verbose HTTP/2 debug logs
	GODEBUG=http2debug=2   # ... even more verbose, with frame dumps

	{Name: "gocachehash", Package: "cmd/go"},
	{Name: "gocachetest", Package: "cmd/go"},
	{Name: "gocacheverify", Package: "cmd/go"},
	{Name: "gotypesalias", Package: "go/types", Changed: 23, Old: "0"},
	{Name: "http2client", Package: "net/http"},
	{Name: "http2debug", Package: "net/http", Opaque: true},
	{Name: "http2server", Package: "net/http"},
	{Name: "httplaxcontentlength", Package: "net/http", Changed: 22, Old: "1"},

The environment variable `GODEBUG`
can hold a comma-separated list of these settings.
For example, if a Go program is running in an environment that contains

	GODEBUG=http2client=0,http2server=0

then that Go program will disable the use of HTTP/2 by default in both
the HTTP client and the HTTP server.
It is also possible to set the default `GODEBUG` for a given program
(discussed below).
