// switch and embeds the dummy manifest file. The linker also generates
// the real manifest file based on the binaries that your binary depends
// on.

// manifest.
// If the final manifest is changed, then 6 and 7 are run, if not
// they are skipped, and it is done.
// 6. The resource compiler is invoked one more time.

// manifest it is a short link.
