=head1 pclient - Crossfire+ and Crossfire game client

Pclient is a Crossfire+ and Crossfire game client.

=head2 Features

=over 4

=item Fullscreen Map

PClient can uses a fullscreen map, which greatly enhances how much of the
game world you can see.

=item Persistent Map Cache (Crossfire+ only)

PClient can persistently cache all map data it received from the
server. This not only allows it to display an overview map, but also
ensures that once-explored areas will be available the next time you want
to explore more.

=item Hardware acceleration

Unlike most Crossfire clients, PClient take advantage of OpenGL hardware
acceleration. Most modern graphics cards have difficulties with 2D
acceleration, while 3D graphics is accelerated well.

=item No arbitrary limits

Unlike other Crossfire clients, pclient does not suffer from arbitrary
limits (like a fixed amount of face numbers). There are still limits, but
they are not arbitrarily low :)

=back

=head1 USAGE

=head2 The Map

The map is always displayed in the background, behind all other windows and UI elements.

Starting to type enters the I<completion mode>. In that mode, you can type
abbreviations or commands and have them executed as soon as they match a
valid command. This is best explained by a few examples:

Typing B<climb> will display a list of commands with I<climb> in their
name, such as I<ready_skill climbing> and I<use_skill climbing>.

You can abbreviate commands by typing only the first character of every
word. For example, typing I<iwor> will likely select I<invoke word of
recall>, while I<ccfo> will select I<cast create food>. Likewise, I<rscli>
will likely select I<ready_skill climbing> and I<usl> will give you
I<use_skill levitation>.

=item The client is very sluggish and slow, what can I do about this?

Most likely, you don't have accelerated OpenGL support. Try to find a
newer driver, or a driver from your hardware vendor, that features OpenGL
support.

If this is not an option, the following Setup options reduce the load and
will likely make the client playable with sofwtare rendering (it will
still be slow, though):
