The Tool Command Language implementation
Tcl(Tool Command Language) provides a powerful platform for creating integration applications that tie together diverse applications, protocols, devices, and frameworks. When paired with the Tk toolkit, Tcl provides the fastest and most powerful way to create GUI applications that run on linux, Unix, and Mac OS X. Tcl can also be used for a variety of web-related tasks and for creating powerful command languages for applications.

The graphical toolkit for the Tcl scripting language
TK is a widget toolkit that creates graphical user interface(GUI). It's especially easy to program a GUI application using tcl script language.
The GNU C Library project provides the core libraries for the GNU system and GNU/Linux systems, as well as many other systems that use Linux as the kernel. These libraries provide critical APIs including ISO C11, POSIX.1-2008, BSD, OS-specific APIs and more. These APIs include such foundational facilities as open, read, write, malloc, printf, getaddrinfo, dlopen, pthread_create, crypt, login, exit and more.
Extended Tcl (TclX) is a set of extensions to the Tcl programming language. Extended Tcl is oriented towards system programming tasks and large application development. TclX provides additional interfaces to the operating system, and adds many new programming constructs, text manipulation and debugging tools.
