# Makefile to build the Handbook from DocBook source.
#
# Requires these ports from textproc
#
#    docbook
#    dsssl-docbook-modular
#    html
#    jade
#
# and probably one or two others. You can probably get everything you need
# with the new textproc/docproj meta-port. 
#
# Note that you need version 1.08 of dsssl-docbook-modular. In version 1.07
# the 'catalog' file is called 'CATALOG', and you will need to change the 
# definition below.
#
# THIS IS A QUICK HACK (!) so that others can get an idea of how the 
# Handbook will look after conversion. After typing "make", point your
# browser at book01.html and read on. This is still very much a work in
# progress, and the final formatting will be considerably different.
#
# Eventually I expect most of this will be folded back into bsd.sgml.mk.
#
# Any comments or suggestions about the conversion process should be sent
# to nik@FreeBSD.ORG
