### Using the `v2` branch
There is currently a long-lived branch named `v2` that is intended to land as
the new `master` branch once development there has settled down. The current
`master` branch (what will become `v1`) is being manually merged into `v2` on an
irregular human schedule, but generally if one wants to "upgrade" to `v2` *now*
and accept the volatility (read: "awesomeness") that comes along with that,
please use whatever version pinning of your preference, such as via `gopkg.in`:
```
$ go get gopkg.in/codegangsta/cli.v2
```
``` go
...
import (
"gopkg.in/codegangsta/cli.v2" // imports as package "cli"
)
...
```
## Getting Started
One of the philosophies behind cli is that an API should be playful and full of discovery. So a cli app can be as little as one line of code in `main()`.
