#    So Makefile rules to update them should put the updated files in the

all-local: $(srcdir)/stamp-po

# $(srcdir)/$(DOMAIN).pot is only created when needed. When xgettext finds no
# internationalized messages, no $(srcdir)/$(DOMAIN).pot is created (because
# we don't want to bother translators with empty POT files). We assume that
# LINGUAS is empty in this case, i.e. $(POFILES) and $(PROPERTIESFILES) are
# empty. In this case, $(srcdir)/stamp-po is a nop (i.e. a phony target).

# $(srcdir)/stamp-po is a timestamp denoting the last time at which the CATALOGS
# have been loosely updated. Its purpose is that when a developer or translator
# checks out the package from a version control system, and the $(DOMAIN).pot
# file is not under version control, "make" will update the $(DOMAIN).pot and
# the $(CATALOGS), but subsequent invocations of "make" will do nothing. This
# timestamp would not be necessary if updating the $(CATALOGS) would always
# touch them; however, the rule for $(POFILES) has been designed to not touch
# files that don't need to be changed.

# have been downloaded.

# This target rebuilds $(DOMAIN).pot; it is an expensive operation.
# Note that $(DOMAIN).pot is not touched if it doesn't need to be changed.
# The determination of whether the package xyz is a GNU one is based on the
# heuristic whether some file in the top level directory mentions "GNU xyz".
# If GNU 'find' is available, we avoid grepping through monster files.
