  30 Send a patch or a range of patches by e-mail using the 'smtpserver'
  31 configuration option. The From address and the e-mail format are
  32 generated from the template file passed as argument to '--template'
  33 (defaulting to '.git/patchmail.tmpl' or
  34 '~/.stgit/templates/patchmail.tmpl' or or
  35 '/usr/share/stgit/templates/patchmail.tmpl'). The To/Cc/Bcc addresses
  36 can either be added to the template file or passed via the
  37 corresponding command line options.
  38
  39 A preamble e-mail can be sent using the '--cover' and/or '--edit'
  40 options. The first allows the user to specify a file to be used as a
  41 template. The latter option will invoke the editor on the specified
  42 file (defaulting to '.git/covermail.tmpl' or
  43 '~/.stgit/templates/covermail.tmpl' or
  44 '/usr/share/stgit/templates/covermail.tmpl').
  45
  46 All the subsequent e-mails appear as replies to the first e-mail sent
  47 (either the preamble or the first patch). E-mails can be seen as
  48 replies to a different e-mail by using the '--refid' option.
  49
  50 SMTP authentication is also possible with '--smtp-user' and
  51 '--smtp-password' options, also available as configuration settings:
  52 'smtpuser' and 'smtppassword'.
  53
  54 The template e-mail headers and body must be separated by
  55 '%(endofheaders)s' variable, which is replaced by StGIT with
  56 additional headers and a blank line. The patch e-mail template accepts
  57 the following variables:
  58
  59   %(patch)s        - patch name
  60   %(maintainer)s   - 'authname <authemail>' as read from the config file
  61   %(shortdescr)s   - the first line of the patch description
  62   %(longdescr)s    - the rest of the patch description, after the first line
  63   %(endofheaders)s - delimiter between e-mail headers and body
  64   %(diff)s         - unified diff of the patch
  65   %(diffstat)s     - diff statistics
  66   %(date)s         - current date/time
  67   %(version)s      - ' version' string passed on the command line (or empty)
  68   %(prefix)s       - 'prefix ' string passed on the command line
  69   %(patchnr)s      - patch number
  70   %(totalnr)s      - total number of patches to be sent
  71   %(number)s       - empty if only one patch is sent or ' patchnr/totalnr'
  72   %(authname)s     - author's name
  73   %(authemail)s    - author's email
  74   %(authdate)s     - patch creation date
  75   %(commname)s     - committer's name
  76   %(commemail)s    - committer's e-mail
  77
  78 For the preamble e-mail template, only the %(maintainer)s, %(date)s,
  79 %(endofheaders)s, %(version)s, %(patchnr)s, %(totalnr)s and %(number)s
  80 variables are supported."""
