  36 ### The default rule
  37 #
  38 # Note: Target `all-local' must not depend on target '$(srcdir)$(PACKAGE).pot',
  39 # otherwise packages like GCC can not be built if only parts of the source have
  40 # been downloaded.
  41 #
  42 # Note 2: We aren't gcc, we are ELinks. And I want that dependency ;-). --pasky
  43 #
  44 # Note 3: I changed my mind, it is really annoying if you just insert one line
  45 # and suddenly you have tons of changes in all the .po files updating the line
  46 # informations. --pasky
  47 #
  48 # $(CATALOGS) is empty if --disable-nls. Beats using *-(yes|no) targets.

  53 ### Creating the template po template file
  54 #
  55 # This pulls in _all_ .c and .h files in the src directory. Even files that has
  56 # not been added to the git repo. Beware of junk entries!
