This repository provides the downloadable example programs for the book, "The Go Programming Language"; see http://www.gopl.io.

Hello, 世界
Many of the programs contain comments of the form //!+ and //!-.
These comments bracket the parts of the programs that are excerpted in the
book; you can safely ignore them. In a few cases, programs
have been reformatted in an unnatural way so that they can be presented
in stages in the book.
