"""Example xend HTTP
Can be accessed from a browser or from a program.
Do 'python SrvServer.py' to run the server.
Then point a web browser at http://localhost:8000/xend and follow the links.
Most are stubs, except /domain which has a list of domains and a 'create domain'
button.
You can also access the server from a program.
Do 'python XendClient.py' to run a few test operations.
The data served differs depending on the client (as defined by User-Agent
and Accept in the HTTP headers). If the client is a browser, data
is returned in HTML, with interactive forms. If the client is a program,
data is returned in SXP format, with no forms.
The server serves to the world by default. To restrict it to the local host
change 'interface' in main().
