KildClient is a MUD Client written with the GTK+ windowing toolkit. It supports many common features of other clients, such as triggers, gags, aliases, macros, timers, and much more. But its main feature is the built-in Perl interpreter. You can at any moment execute Perl statements and functions to do things much more powerful than simply sending text the the mud. Perl statements can also be run, for example, as the action of a trigger, allowing you to do complex things. Some built-in functions of KildClient allow interaction with the world, such as sending commands to it.
You can specify the name of one or more saved Worlds in the command line, this/these World(s) will be automatically opened. If you do not specify any World, you are prompted for the MUD to connect to. You can enter the host and port directly, or you can select from a list of saved MUDs. Once connected, type commands in the separate entry box and press ENTER to send them to the MUD. You can edit the commands before sending, since they only get sent when ENTER is pressed. You can recall previous commands with the arrow keys, or by pressing the button to the right of the command entry box.
There are many more features, many options for configuring the program's behaviour. For more details, see the KildClient manual, which is usually installed in the /usr/share/doc/kildclient directory.
The full manual, in HTML and PDF formats, is included with the package. It can generally be found in the /usr/share/doc/kildclient directory.
