A static file server

# Serves a directory over HTTP, like `python -m http.server`.
#
#   sd run examples/serve.sd                 # the current directory, on port 8000
#   sd run examples/serve.sd 9000            # another port
#   sd run examples/serve.sd 9000 public     # another directory
#
# Each request is handled on a thread of its own (ThreadingHTTPServer), and
# SimpleHTTPRequestHandler gets its directory through functools.partial, as in Python.
# The same file runs under python3.
