It is most commonly used for rapid prototyping, scripted applications, GUIs and testing. Tcl is used extensively on embedded systems platforms, both in its full form and in several other small-footprinted versions. Tcl is also used for CGI scripting and as the scripting language for eggdrop bots. [...]

Most servers allow users to connect at all times 24/7. There is a possibility to attach the programs by using the GNU screen terminal multiplexer. [...]
