This is a first shot guide to running xtet42 in two-player mode.

To start xtet42 om some friend's display, you need permissions to open the
window on her display. This can be achieved several ways, but the simplest
is for your friend to type:

	xhost +your.host.somewhere.net

WARNING: this allows ANY user on your.host.somewhere.net to open windows
on her display. Use with caution! Permissions can be used for naughty
things, so only give people you TRUST access to your display.

She should NEVER do "xhost +" (no host specified). This gives ANY user on
ANY host on the network access to your display.

Now it is time to start xtet42. You could type:

	xtet42 -p1 YourName -p2 Friend -m2 friends.host.somewhere.net:0

-p1 and -p2 are used to set nicknames. These names will appear in the
hi-score file.
-m1 and -m2 are used to set display or host names for the players.

-p1 and -m1 defaults to the loginname and $DISPLAY or the player who is
starting the game.

As soon as the window opens, your friend should type:

	xhost -your.host.somewhere.net

to undo the access rights for her display given earlier. 

Then, have fun. (To do this, you can win the game)
