# $(srcdir)/$(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 $(GMOFILES) are empty.
# In this case, stamp-po is a nop (i.e. a phony target).
# 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 via CVS, and the $(DOMAIN).pot file is not in CVS,
# "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.

# Note: Target 'all' must not depend on target '$(DOMAIN).pot-update',

# 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.
