# libbind2netbsd:  convert abind tree into a
# netbsd libbind source tree, under src/external/bsd,
# based on bind2netbsd by Bernd Ernesti and changes by Simon Burge
#
# Rough instructions for importing new bind release:
#
#	$ cd /some/where/temporary
#	$ tar xpfz /new/bind/release/tar/file
#	$ sh /usr/src/external/bsd/libbind/dist/libbind2netbsd libbind-6.x.y `pwd`
#	$ cd src/external/bsd/libbind/dist
#	$ cvs import -m "Import libbind 6.x.y" src/external/bsd/libbind/dist ISC libbind-6-x-y
#	$ cd ../../../../../libbind-6.x.y
#	$ run ./configure
#	$ run make
#	- use the binclude4netbsd to create and import the new headers in
#	  /usr/src/usr.sbin/bind/include
#	- check makefiles to see if any extra sources have been added.
#	- update distrib/sets if necessary.
