pub fn print_version_info()Expand description
Print rich version & system environment details for -v / -V / –version.
This, not clap, is what devp --version actually runs — [normalize_args] catches the
flag first. The author and repository are printed here because a copy of this binary
found on a machine with no package manager record should still be able to say where it
came from, and --version is the first thing anyone runs on an unknown executable.
