libbind9 in BIND 9.3

[Stefan Puiu]

Hello,

I see there's a new directory in the BIND 9.3 source under lib/, namely 
lib/bind9 - and a new library that is being installed on both UNIX and 
Windows, libbind9.a or libbind9.dll. What is it used for? I see that 
check.c used to be in libisccfg in 9.2.3 and includes functions one can 
use to check BIND 9 configuration files, and getaddresses.c seems to 
provide a function for querying a nameserver for its IPv4 and IPv6 
addresses, but they don't have any comments inside to explain what 
they're supposed to, so the best I can do is guess. Is my guess right? 
Is it intended to grow into a replacement for the old libbind resolver 
library, or is it intended only to be used for simple address resolution 
(and configuration parsing)?

Thanks in advance.
