Frontend tool

what´s a “frontend tool” (ie “CCD4 Profiler is a frontend tool for CloneCD 4.”. another in this: this ccd4 profiler isn´t just a copy of the alcoholer? or it was since from earlier versions of alcholer, when perhaps it was only designed for alcohol 120%)

a GUI so you have buttons and options to click on instead of running the program from a command line.

do not know a thing about clonecd
