Go Systems Programming

Using standard Go packages

You probably already know how to use the standard Go packages. However, what you may not be aware of is the fact that some packages have a structure. So, for example, the net package has several sub directories, named http, mail, rpc, smtp, textproto, and url, which should be imported as net/http, net/mail, net/rpc, net/smtp, net/textproto, and net/url, respectively. Go groups packages when this makes sense, but these packages could have also been isolated packages if they were grouped for distribution instead of functionality.

You can find information about a Go standard package with the help of the godoc utility. So, if you are looking for information about the net package, you should execute godoc net.
