/*
name - applet name as it is typed on command line
name2 - applet name, converted to C (ether-wake: name2 = ether_wake)
main - <applet>_main part (e.g. for bzcat: main = bunzip2)
l - location ([/usr]/[s]bin)
s - suid type:
_BB_SUID_ALWAYS: will complain if busybox isn't suid
and is run by non-root (applet_main() will not be called at all)
_BB_SUID_NEVER: will drop suid prior to applet_main()
_BB_SUID_MAYBE: neither of the above
