  18DESCRIPTION
  19-----------
  20Splits mail messages in a mailbox into commit log message,
  21authorship information and patches, and applies them to the
  22current branch.
  23
  24OPTIONS
  25-------
  26<mbox>|<Maildir>...::
  27        The list of mailbox files to read patches from. If you do not
  28        supply this argument, reads from the standard input. If you supply
  29        directories, they'll be treated as Maildirs.
  30
  31-s, --signoff::
  32        Add `Signed-off-by:` line to the commit message, using
  33        the committer identity of yourself.
  34
  35-d=<dir>, --dotest=<dir>::
  36        Instead of `.dotest` directory, use <dir> as a working
  37        area to store extracted patches.
  38
  39-k, --keep::
  40        Pass `-k` flag to `git-mailinfo` (see linkgit:git-mailinfo[1]).
  41
  42-u, --utf8::
  43        Pass `-u` flag to `git-mailinfo` (see linkgit:git-mailinfo[1]).
  44        The proposed commit log message taken from the e-mail
  45        is re-coded into UTF-8 encoding (configuration variable
  46        `i18n.commitencoding` can be used to specify project's
  47        preferred encoding if it is not UTF-8).
  48+
  49This was optional in prior versions of git, but now it is the
  50default.   You could use `--no-utf8` to override this.
  51
  52--no-utf8::
  53        Pass `-n` flag to `git-mailinfo` (see
  54        linkgit:git-mailinfo[1]).
  55
  56-3, --3way::
  57        When the patch does not apply cleanly, fall back on
  58        3-way merge, if the patch records the identity of blobs
  59        it is supposed to apply to, and we have those blobs
  60        available locally.
  61
  62-b, --binary::
  63        Pass `--allow-binary-replacement` flag to `git-apply`
  64        (see linkgit:git-apply[1]).
  65
  66--whitespace=<option>::
  67        This flag is passed to the `git-apply` (see linkgit:git-apply[1])
  68        program that applies
  69        the patch.
  70
  71-C<n>, -p<n>::
  72        These flags are passed to the `git-apply` (see linkgit:git-apply[1])
  73        program that applies
  74        the patch.
  75
  76-i, --interactive::
  77        Run interactively.
  78
  79--skip::
  80        Skip the current patch.  This is only meaningful when
  81        restarting an aborted patch.
  82
  83-r, --resolved::
  84        After a patch failure (e.g. attempting to apply
  85        conflicting patch), the user has applied it by hand and
  86        the index file stores the result of the application.
  87        Make a commit using the authorship and commit log
  88        extracted from the e-mail message and the current index
  89        file, and continue.
  90
  91--resolvemsg=<msg>::
  92        When a patch failure occurs, <msg> will be printed
  93        to the screen before exiting.  This overrides the
  94        standard message informing you to use `--resolved`
  95        or `--skip` to handle the failure.  This is solely
  96        for internal use between `git-rebase` and `git-am`.
  97
  98DISCUSSION
  99----------
 100
 101The commit author name is taken from the "From: " line of the
 102message, and commit author time is taken from the "Date: " line
 103of the message.  The "Subject: " line is used as the title of
 104the commit, after stripping common prefix "[PATCH <anything>]".
 105It is supposed to describe what the commit is about concisely as
 106a one line text.
 107
 108The body of the message (iow, after a blank line that terminates
 109RFC2822 headers) can begin with "Subject: " and "From: " lines
 110that are different from those of the mail header, to override
 111the values of these fields.
 112
 113The commit message is formed by the title taken from the
 114"Subject: ", a blank line and the body of the message up to
 115where the patch begins.  Excess whitespaces at the end of the
 116lines are automatically stripped.
 117
 118The patch is expected to be inline, directly following the
 119message.  Any line that is of form:
 120
 121* three-dashes and end-of-line, or
 122* a line that begins with "diff -", or
 123* a line that begins with "Index: "
 124
 125is taken as the beginning of a patch, and the commit log message
 126is terminated before the first occurrence of such a line.
 127
 128When initially invoking it, you give it names of the mailboxes
 129to crunch.  Upon seeing the first patch that does not apply, it
 130aborts in the middle,.  You can recover from this in one of two ways:
 131
 132. skip the current patch by re-running the command with '--skip'
 133  option.
 134
 135. hand resolve the conflict in the working directory, and update
 136  the index file to bring it in a state that the patch should
 137  have produced.  Then run the command with '--resolved' option.
 138
 139The command refuses to process new mailboxes while `.dotest`
 140directory exists, so if you decide to start over from scratch,
 141run `rm -f -r .dotest` before running the command with mailbox
 142names.
