## NAME
       git-mailsplit - Simple UNIX mbox splitter program

## SYNOPSIS
       git mailsplit [-b] [-f<nn>] [-d<prec>] [--keep-cr] [--mboxrd]
                       -o<directory> [--] [(<mbox>|<Maildir>)...]

## DESCRIPTION
       Splits a mbox file or a Maildir into a list of files: "0001" "0002" ..
       in the specified directory so you can process them further from there.

           Important
           Maildir splitting relies upon filenames being sorted to output
           patches in the correct order.

## OPTIONS
       <mbox>
           Mbox file to split. If not given, the mbox is read from the
           standard input.

       <Maildir>
           Root of the Maildir to split. This directory should contain the
           cur, tmp and new subdirectories.

### -o<directory>
           Directory in which to place the individual messages.

### -b
           If any file doesn't begin with a From line, assume it is a single
           mail message instead of signaling error.

### -d<prec>
           Instead of the default 4 digits with leading zeros, different
           precision can be specified for the generated filenames.

### -f<nn>
           Skip the first <nn> numbers, for example if -f3 is specified, start
           the numbering with 0004.

### --keep-cr
           Do not remove \r from lines ending with \r\n.

### --mboxrd
           Input is of the "mboxrd" format and "^>+From " line escaping is
           reversed.
