/* A demonstration of using HTTP basic authentication with XML-RPC.
**
** In general, you shouldn't write XML-RPC servers which require basic
** authenticaion. (Few XML-RPC clients are capable of it, and it's not part of
** any standard.) Instead, you should pass any authentication information
** as a regular XML-RPC parameter (or look into using SSL).
**
** But certain XML-RPC servers, including Zope, rely heavily on HTTP
** basic authentication. Here's how to talk to them. */
