.Sh NAME
.Nm mgpnet
.Nd MagicPoint Netserver (provide MagicPoint presentation over the net)
.Sh SYNOPSIS
.Nm mgpnet
.Op arguments to mgp
.Sh DESCRIPTION
.Nm 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.
.Pp
When a presenter performs a presentation, she should invoke
.Nm mgpnet
instead of
.Nm mgp ,
with the same argument.
.Nm mgpnet
will become an http server running on tcp port 9999 (by default),
and invokes
.Nm mgp
as a child process.
By accessing URL
.Fa http://hostname:9999/ ,
audience will be able to read the MagicPoint window currently displayed
on the presenter's notebook.
The webpage provided by
.Nm mgpnet
is designed in "client pull" manner;
audience's notebook will reload the page, several times a minute.
.Pp
If no option is specified,
.Nm 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:
.Bd -literal
%filter "mgpnet"
%endfilter
.Ed
.Sh TODO
Be network conscious.
Current implementation is too naive about CPU/network usage.
Presenter's notebook may be overloaded if there's too many audiences.
