title: With Go's webserver where does the root of the website map onto the filesystem?
body: <p>Where is the filesystem "root" of a Go <code>net/http</code> webserver. It doesn't seem to be in the directory the executable is in.
  By "root" I mean the directory I would use for, say, the <code>src</code> attribute of an <code>img</code>, without any path. I don't plan to do this, but it would help me understand the structure if I knew.</p>
