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"
12 ## The patch application may fail in the middle. In which case:
13 ## (1) look at .dotest/patch and fix it up to apply
14 ## (2) re-run applymbox with -c .dotest/msg-number for the current one.
15 ## Pay a special attention to the commit log message if you do this and
16 ## use a Signoff_file, because applypatch wants to append the sign-off
17 ## message to msg-clean every time it is run.
19 ## git-am is supposed to be the newer and better tool for this job.
