	Short:     "print Go environment information",
	Long: `
Env prints Go environment information.

By default env prints information as a shell script
(on Windows, a batch file). If one or more variable
names is given as arguments, env prints the value of
each named variable on its own line.

The -json flag prints the environment in JSON format
instead of as a shell script.

The -u flag requires one or more arguments and unsets
the default setting for the named environment variables,
if one has been set with 'go env -w'.

The -w flag requires one or more arguments of the
form NAME=VALUE and changes the default settings
of the named environment variables to the given values.

The -changed flag prints only those settings whose effective
value differs from the default value that would be obtained in
an empty environment with no prior uses of the -w flag.

For more about environment variables, see 'go help environment'.
