Package is the overall, canonical project import path under which the package was built.
var Package = "github.com/docker/distribution"
Revision is filled with the VCS (e.g. git) revision being used to build the program at linking time.
var Revision = ""
Version indicates which version of the binary is running. This is set to the latest release tag by hand, always suffixed by "+unknown". During build, it will be replaced by the actual version. The value here will be used if the registry is run after a go get based install.
var Version = "v2.8.3+unknown"
func FprintVersion(w io.Writer)
FprintVersion outputs the version string to the writer, in the following format, followed by a newline:
<cmd> <project> <version>
For example, a binary "registry" built from github.com/docker/distribution with version "v2.0" would print the following:
registry github.com/docker/distribution v2.0
func PrintVersion()
PrintVersion outputs the version information, from Fprint, to stdout.
