# heimdal2netbsd:  convert a heimdal source tree into a
# netbsd heimdal source tree, under src/crypto/external/bsd/heimdal/dist
# based on bind2netbsd by Bernd Ernesti and changes by Simon Burge
#
# Rough instructions for importing new heimdal release from their git
# repository:
#
#	$ export SRCDIR=/usr/src
#	$ export HEIMDAL_SRCDIR=src/crypto/external/bsd/heimdal
#	$ cd /some/where/temporary
#	$ git clone git@github.com:heimdal/heimdal.git
#	$ sh $SRCDIR/../$HEIMDAL_SRCDIR/heimdal2netbsd heimdal `pwd`
#	$ cd $HEIMDAL_SRCDIR/dist
#       $ cvs -d ... import $HEIMDAL_SRCDIR/dist HEIMDAL head-20110317
#	>>> if any conflicts, merge, fix and commit them.
#	$ cd /some/where/temporary/heimdal
#	$ autoreconf -f -i
#	$ ./configure
#	$ make
#	>>> merge newly generated config.h
#	>>> with $HEIMDAL_SRCDIR/include/config.h
#	>>> and check out diffs in generated headers
#	>>> and C files.
#	$ cd ..
#	$ rm -r src heimdal
#	$ cd $SRCDIR/$HEIMDAL_SRCDIR
#	$ cvs commit -m "Updated generated files for Heimdal head-20110317"
#
#	- check makefiles to see if any extra sources have been added.
#	- update distrib/sets if necessary.
