The GNU Hello program produces a familiar, friendly greeting.
Yes, this is another implementation of the classic program that
prints “Hello, world!” when you run it.
However, unlike the minimal version often seen, GNU Hello processes
its argument list to modify its behavior, supports greetings in many
languages, and so on. The primary purpose of GNU Hello is to
demonstrate how to write other programs that do these things; it
serves as a model for GNU coding standards and GNU maintainer
practices.
