getopt-like behavior in Go

Question

How do I nicely parse a list of program parameters and automate handling \"--help\" and/or \"--version\" (such as \"program [-d value] [--abc] [FILE1]\") in Go?

Answer 1

Use the 'flag' package: http://golang.org/pkg/flag/. It doesn't do double-dash arguments, however. There isn't anything that exactly mimics GNU getopt behaviour (yet.)
