   3 ## "dotest" is my stupid name for my patch-application script, which
   4 ## I never got around to renaming after I tested it. We're now on the
   5 ## second generation of scripts, still called "dotest".
   6 ##
   7 ## Update: Ryan Anderson finally shamed me into naming this "applymbox".
   8 ##
   9 ## You give it a mbox-format collection of emails, and it will try to
  10 ## apply them to the kernel using "applypatch"
  11 ##
  12 ## applymbox [ -c .dotest/msg-number ] [ -q ] mail_archive [Signoff_file]"
  13 ##
  14 ## The patch application may fail in the middle.  In which case:
  15 ## (1) look at .dotest/patch and fix it up to apply
  16 ## (2) re-run applymbox with -c .dotest/msg-number for the current one.
  17 ## Pay a special attention to the commit log message if you do this and
  18 ## use a Signoff_file, because applypatch wants to append the sign-off
  19 ## message to msg-clean every time it is run.
