"""Extend Python's built in HTTP server to save files
curl or wget can be used to send files with options similar to the following
  curl -X PUT --upload-file somefile.txt http://localhost:8000
  wget -O- --method=PUT --body-file=somefile.txt http://localhost:8000/somefile.txt
__Note__: curl automatically appends the filename onto the end of the URL so
the path can be omitted.
