Xconfig
xconfig is short for the 'xconfig' target for the Linux Makefile. It is a graphical Linux compilation utility, which uses Qt. The xconfig utility is invoked by running 'make xconfig' in the base Linux source directory.
Qt has only been used since kernel 2.6. Kernel 2.4 uses a Tcl/Tk configuration interface. A GTK+ interface is also available since kernel 2.6.
Inside, there are options to display the configurations in 3 different hierarchies; single, split, full. A Find function is available to search for text within the config's titles.
