-      If the argument to <a href="/pkg/archive/tar#FileInfoHeader"><code>FileInfoHeader</code></a> implements the new <a href="/pkg/archive/tar#FileInfoNames"><code>FileInfoNames</code></a> interface, then the interface methods will be used to set the UID/GID of the file header. This allows applications to override the default UID/GID resolution.
