mgpnet is a small http server to be executed on the presenter's notebook computer. It lets audience read
MagicPoint presentation foils on her notebook computers, over the net.
When a presenter performs a presentation, she should invoke mgpnet instead of mgp, with the same
argument. mgpnet will become an http server running on tcp port 9999 (by default), and invokes mgp as a
child process. By accessing URL http://hostname:9999/, audience will be able to read the MagicPoint
window currently displayed on the presenter's notebook. The webpage provided by mgpnet is designed in
"client pull" manner; audience's notebook will reload the page, several times a minute.
If no option is specified, mgpnet will print the URL to be accessed by the audience to the standard
output. This is useful for indicating the URL to be accessed on the presentation, like:
%filter "mgpnet"
