        skillsets, YOU can make the world a better place!
        \_ So, um, I've monkeyed with all those tools, except nc, what's
           nc?
           \_ Netcat, likely.  -John
              \- you forgot xargs, mapcar and apply
                 \_ these are really basic, "small steps" skillsets
                    like ls, man, less. -op
                 \_ He didn't ask about tools.   He asked about nc. -John
        \_ Knowing gdb is a lot more important than ddd
