Counts down for a duration (like sleep, but with progress)

1. Download the latest package for your platform from the Releases page.
2. Untar the package with tar -zxvf cachout*.tar.gz.
3. Move the extracted countdown file to a directory in your $PATH (for most systems, this will be /usr/local/bin/).

Or, if you have a Go development environment:

go get github.com/justincampbell/countdown

countdown 5m

The duration is parsed with Go's time.ParseDuration.

Example durations are 30s, 5m, 2h, or 1h30m. Omitting the time unit will default to seconds.
