DESCRIPTION
Print version information.
You can format the output with a go template using the --format flag.
Typically, to only output a parsable version, call:
$ ` + os.Args[0] + ` version -f '{{.Version}}'
As reference, known attributes are:
- PackageLabel
- Version
- BuildTime
- GitCommit
- OS
- Arch
- GoVersion
