### The default rule
#
# Note: Target `all-local' must not depend on target '$(srcdir)$(PACKAGE).pot',
# otherwise packages like GCC can not be built if only parts of the source have
# been downloaded.
#
# Note 2: We aren't gcc, we are ELinks. And I want that dependency ;-). --pasky
#
# Note 3: I changed my mind, it is really annoying if you just insert one line
# and suddenly you have tons of changes in all the .po files updating the line
# informations. --pasky
#
# $(CATALOGS) is empty if --disable-nls. Beats using *-(yes|no) targets.
all-local: $(CATALOGS)
### Creating the template po template file
#
# This pulls in _all_ .c and .h files in the src directory. Even files that has
# not been added to the git repo. Beware of junk entries!

# either <lang> or <lang>.po when calling make. Example: make update-po PO=is
