-* Some files in the automake package are not owned by automake (many by
-  gnulib, https://gnu.org/s/gnulib); these files are listed in the
-  $(FETCHFILES) variable in Makefile.am.  They should never be edited
-  here.  All but one of them can be updated from respective upstreams
-  with "make fetch" (this should be done especially before releases).
-  The only exceptions are help2man (install the current version) and
-  'lib/COPYING' (from FSF), which should be updated by hand whenever the
-  GPL gets updated (which shouldn't happen that often anyway :-).
