   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.
