Tcl

Tcl is a scripting language written by John Ousterhout. When Eggdrop was first written, Tcl was a strong choice to extend Eggdrop's functionality. It is a standalone scripting language (different than "built-in" script languages such as the one in ircII or mirc) The file "tcl-commands.doc" in the doc directory contains a list of Tcl added by Eggdrop. There are also several example scripts in the scripts/ directory, and one in the doc directory called first_script.txt, as well as hundreds of scripts that can be found on www.tclarchive.net or a quick Google search
