There are several programs that make Linux easy to setup and configure. Some
are becoming sort of standard: Red Hat, Caldera and other distributions ship
with apps like printtool, netcfg, usertool, etc,
while S.u.S.E. ships with a comprehensive configuration program called YAST.
Other useful programs are:
emacs, bash, procmail and more. Its
