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 .

PrintVersion outputs the version information, from Fprint, to stdout.

Package is the overall, canonical project import path under which the package was built.

Version indicates which version of the binary is running.
