# This makefile creates "wrapper" files that combine sets of
# individual DocBook source files. The purpose of combining the
# files is to speed up processing time. By default it puts 20
# files into each wrapper. Use CHUNKSIZE to configure the number
# of files per wrapper.
#
# Currently, this makefile has only a "man" target and is mainly
# intended to speed up processing of large numbers of individual
# refentry instances.

# What file extension do you use for DocBook source files?
