I though that requirement for all busybox contributions is GPL license. This was the \
reason why I licensed applet under GPLv2. If ISC license is acceptable for you, I'm \
also for it. Proposed patch is attached and after agreement, license can be copied to \
ntpd_simple.c...

Please note that I removed "portability layer" authors mentioned in OpenNTPd license \
because this portability layer code was never used by applet (everything was replaced \
by already existing libbb code).

All of them are CC-ed. If you don't agree with ISC-style license for ntpd.c (and \
attached patch), please tell us...

Subject: [PATCH] Relicense ntpd applet to ISC-style license

OpenNTPd is licensed under ISC-style license so it's good idea to keep ntpd
applet under same license to avoid mess.

Original authors copyrights were added.
