The git-am script is nowhere called and nowhere (including itself) explained, and the name isn't helpful either. For those like me who will wonder what is it about, add some documentation stub for it to the documentation. I probably got something wrong and I don't feel like investigating all the options - this is just kind of "emergency" docs.

## "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.
