# Generate makefile from qpidd --help
#
# Note: qiddd.1 is normally a _checked in_ pre-generated file, so that
# make dist does not have to build the entire source just for the man page.
#
# To update the checked-in file (e.g. for a new release) do the following:
#
# - start with a completely clean checkout.
# - make sure there are no modules installed in your configured prefix,
#   we don't want to pick up configuration from optional modules
# - do bootstrap; configure
# - in build-dir: cd src; make # build the broker
# - in source-dir: cd docs/man; rm qpidd.1 # remove checked-in man page.
# - in build-dir: cd docs/man; make # make new man page
# - edit qpidd.1 to remove all default values referring to file/directory locations.
#   these values will differ between builds depending on configuration.
# - if source-dir != build-dir: copy qpidd.1 from build-dir/docs/man to source-dir/docs/man
