  29
  30 Send a patch or a range of patches (defaulting to the applied patches)
  31 by e-mail using the 'smtpserver' configuration option. The From
  32 address and the e-mail format are generated from the template file
  33 passed as argument to '--template' (defaulting to .git/patchmail.tmpl
  34 or /usr/share/stgit/templates/patchmail.tmpl). The To/Cc/Bcc addresses
  35 can either be added to the template file or passed via the
  36 corresponding command line options.
  37
  38 A preamble e-mail can be sent using the '--cover' and/or '--edit'
  39 options. The first allows the user to specify a file to be used as a
  40 template. The latter option will invoke the editor on the specified
  41 file (defaulting to .git/covermail.tmpl or
  42 /usr/share/stgit/templates/covermail.tmpl).
  43
  44 All the subsequent e-mails appear as replies to the first e-mail sent
  45 (either the preamble or the first patch). E-mails can be seen as
  46 replies to a different e-mail by using the '--refid' option.
  47
  48 SMTP authentication is also possible with '--smtp-user' and
  49 '--smtp-password' options, also available as configuration settings:
  50 'smtpuser' and 'smtppassword'.
  51
  52 The template e-mail headers and body must be separated by
  53 '%(endofheaders)s' variable, which is replaced by StGIT with
  54 additional headers and a blank line. The patch e-mail template accepts
  55 the following variables:
  56
  57   %(patch)s        - patch name
  58   %(maintainer)s   - 'authname <authemail>' as read from the config file
  59   %(shortdescr)s   - the first line of the patch description
  60   %(longdescr)s    - the rest of the patch description, after the first line
  61   %(endofheaders)s - delimiter between e-mail headers and body
  62   %(diff)s         - unified diff of the patch
  63   %(diffstat)s     - diff statistics
  64   %(date)s         - current date/time
  65   %(version)s      - ' version' string passed on the command line (or empty)
  66   %(patchnr)s      - patch number
  67   %(totalnr)s      - total number of patches to be sent
  68   %(number)s       - empty if only one patch is sent or ' patchnr/totalnr'
  69   %(authname)s     - author's name
  70   %(authemail)s    - author's email
  71   %(authdate)s     - patch creation date
  72   %(commname)s     - committer's name
  73   %(commemail)s    - committer's e-mail
  74
  75 For the preamble e-mail template, only the %(maintainer)s, %(date)s,
  76 %(endofheaders)s, %(version)s, %(patchnr)s, %(totalnr)s and %(number)s
  77 variables are supported."""
