| ## "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. |
