Python webserver that supports PUT method to receive and save files.

put-webserver.py

#!/usr/bin/env python

"""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.
