+##
+## "dotest" is my stupid name for my patch-application script, which
+## I never got around to renaming after I tested it. We're now on the
+## second generation of scripts, still called "dotest".
+##
+## Update: Ryan Anderson finally shamed me into naming this "applymbox".
+##
+## You give it a mbox-format collection of emails, and it will try to
+## apply them to the kernel using "applypatch"
+##
+## The patch application may fail in the middle.  In which case:
+## (1) look at .dotest/patch and fix it up to apply
+## (2) re-run applymbox with -c .dotest/msg-number for the current one.
+## Pay a special attention to the commit log message if you do this and
+## use a Signoff_file, because applypatch wants to append the sign-off
+## message to msg-clean every time it is run.
+##
+## git-am is supposed to be the newer and better tool for this job.
