This is the library formerly known as
github.com/codegangsta/cli -- Github will automatically redirect requests to this repository, but we recommend updating your references for clarity.
cli is a simple, fast, and fun package for building command line apps in Go. The goal is to enable developers to write fast and distributable command line applications in an expressive way.
Command line apps are usually so tiny that there is absolutely no reason why your code should not be self-documenting. Things like generating help text and parsing command flags/options should not hinder productivity when writing a command line app.
This is where cli comes into play. cli makes command line programming fun, organized, and expressive!
