What the heck is Tcl?
Tcl is a scripting language written by John Ousterhout. It’s much better than most “built-in” script languages (like the one in ircII) and is meant to be linked with anything needing a scripting language, so I linked it with Eggdrop. Eggdrop Tcl Commands contains a list of additional Tcl commands provided by Eggdrop. There are also several example scripts in the scripts/ directory, and one in the doc directory called first_script.txt. There are also hundreds of scripts floating around on the ftp/web sites if you like working by example (which is typically the best way).
