  52 ## --- Some hacking for the bootstrapping process ---
  53 ##
  54 ## The outputtable library gets built from `qqlib.c'.  I therefore have to
  55 ## build a `quine' which can do this.  This is `xquine'.  Then, I can
  56 ## build a `yquine' which is capable of writing full `qqout.c' files, with
  57 ## which I can build the final glorious `quine'.

  69 ## --- The `qqlout.c' file ---
  70 ##
  71 ## The contents of `qqlib.c' are included in every `qqout.c' file we write.
  72 ## But I've got to get it from somewhere so that I can write it to the first
  73 ## `qqout.c' file.  The solution is, as described above, to use a cut-down
  74 ## `quine' program which can just about build `qqlout.c' which contains only
  75 ## the library.
