+as the old BSD gethostbyname() standard API.  It was previously also maintained by ISC and distributed with BIND
 and libbind.  The handoff of the maintainership from ISC to NetBSD happened in July 2013.
+
+Bug fixes and development discussion for this code can be discussed on the tech-userlevel mailing list.
+
+Patches of NetBSD (June 2013 head) against libbind-6.0 are available at:
+<http://ftp.netbsd.org/pub/NetBSD/misc/reed/libbsdnet/>
+
+libbind provides portability headers: port_before.h and  port_after.h
+
+### port
+port directory provides portability headers for many operating sytems
+make directory provides common Makefile rules and mkdep
+
+### bsd
+bsd directory contains compatibility code, such as:
+daemon(), \_\_ftruncate(), isc\_\_gettimeofday(), gettimeofday(),
+mkstemp(), mktemp(), gettemp(), putenv(), \_\_readv(), setenv(),
+unsetenv(), findenv(), \_\_setitimer(), strcasecmp(), strncasecmp(),
+strdup(), isc_strerror(), strpbrk(), strsep(), strtoul(), \_\_utimes(),
+\_\_writev(), \_\_writev()
+
+### dst
+dst directory contains the Digital Signature Toolkit
+code for the DST API and crypto API.
+The dst code is not included in NetBSD's src. Probably the code in src/lib/libc using it actually is
+not used.
+
+### inet
+
+src/common/lib/libc/inet/inet_addr.c
+
+NetBSD adds \_inet_aton.c and \_inet_pton.c
+
+libbind has (and NetBSD does not have) inet_data in inet.
+
+### irs
+irs is the Information Retrieval System; it provides
+getaddrinfo, gethostbyname, and related.
+NetBSD doesn't include irs directory as is. But is comparable
+to some of what we have in src/lib/libc/net/
+
+NetBSD doesn't have
+dns.c top-level accessor function for the dns,
+dns_gr.c for hesiod, 
+gai_strerror.c,
+and more.
+
+### isc
+isc directory provides many portability functions
+primarily used for ISC software.
+
+NetBSD only ships with:
+src/lib/libc/include/isc/assertions.h
+src/lib/libc/include/isc/dst.h
+src/lib/libc/include/isc/list.h
+src/lib/libc/include/isc/memcluster.h
+src/lib/libc/include/isc/eventlib.h
+src/lib/libc/include/isc/heap.h
+src/lib/libc/isc/assertions.c
+src/lib/libc/isc/ev_streams.c
+src/lib/libc/isc/ev_timers.c
+src/lib/libc/isc/eventlib_p.h
+
+### nameser
+
+nameser provides the name resolver routines to parse DNS responses
+
+libbind has (and NetBSD does not have) in nameser:
+ns_date.c which provides ns_datetosecs(), isleap(), and datepart();
+ns_newmsg.c  for building DNS message packets;
+ns_rdata.c for unpacking or comparing rdata; and
+ns_sign.c and for ns_verify.c for tsig.
+
+### resolv
+
+NetBSD adds \_\_dn_comp.c, \_\_res_close.c, \_\_res_send.c,
+h_errno.c, res_compat.c, and res_state.c.
+
+libbind has (and NetBSD does not have) in resolv
+(even though NetBSD manual documents them):
+res_findzonecut.c,
+res_mkupdate.c,
+res_sendsigned.c,
+and
+res_update.c.
+
+### tests
+tests directory contains dig tool from bind8
