specified on the command line, the user will be prompted with a ReadLine
enabled interface to provide the necessary information.
+There are two formats accepted for patch files:
+
+1. mbox format files
++
+This is what linkgit:git-format-patch[1] generates. Most headers and MIME
+formatting are ignored.
+
+2. The original format used by Greg Kroah-Hartman's 'send_lots_of_email.pl'

+This format expects the first line of the file to contain the "Cc:" value
+and the "Subject:" of the message as the second line.
