"""Python Web Server with upload functionality and SSL.

This module builds on BaseHTTPServer by implementing the standard GET
and HEAD requests in a fairly straightforward manner.

For initial version, see: https://gist.github.com/UniIsland/3346170

Updated by midnightseer to include the ssl wrapper and command line options
