$this: download binaries for {{ $.Release.GitHub.Owner }}/{{ $.Release.GitHub.Name }}

Usage: $this [-b bindir] [-d] [tag]
  -b sets bindir or installation directory, Defaults to ./bin
  -d turns on debug logging
  [tag] is a tag from
  https://github.com/{{ $.Release.GitHub.Owner }}/{{ $.Release.GitHub.Name }}/releases
  If tag is missing, then the latest release will be used.
