  12 # m4 depends on lex which depends on m4.  Jeeze, gimme a break!  To break
  13 # this loop we manually lex tokenizer.l and installed it in the source
  14 # tree as manual_tokenizer.c.  Now we can build m4 without needing lex.
  15 #
  16 # To regenerate manual_tokenizer.c rename manual_tokenizer.c to tokenizer.l
  17 # and manual_tokenizer.o to tokenizer.o, build, copy tokenizer.c from the
  18 # obj dir to manual_tokenizer.c here, and then adjust the Makefile back to
  19 # using manual_tokenizer.c.
  20 #
  21 # A pox on whatever idiots who thought making lex depend on m4 was a good
  22 # idea.  m4 is such a piece of crap, nobody should be using it anymore.
