# The help2man call
# =================
# Make the rules always dependant on source (thus on postgresql-setup.in, not on
# postgresql-setup), at least for distributed files.  Otherwise, the '*.1'
# manual page is regenerated even when distributed and no code change actually
# happened.  In case there exists some target generating other file directly
# depending on the generated manual page, we would need 'touch $@'.  But it
# seems better to keep warning user about non-existing help2man when '.in'
# changed.
# TODO: make it non-fatal for cross-compilation case also
# TODO: separate it to its own m4 module (for easier distribution)
