  31
  32 Send a patch or a range of patches by e-mail using the SMTP server
  33 specified by the 'stgit.smtpserver' configuration option, or the
  34 '--smtp-server' command line option. The From address and the e-mail
  35 format are generated from the template file passed as argument to
  36 '--template' (defaulting to '.git/patchmail.tmpl' or
  37 '~/.stgit/templates/patchmail.tmpl' or
  38 '/usr/share/stgit/templates/patchmail.tmpl'). A patch can be sent as
  39 attachment using the --attach option in which case the 'mailattch.tmpl'
  40 template will be used instead of 'patchmail.tmpl'.
  41
  42 The To/Cc/Bcc addresses can either be added to the template file or
  43 passed via the corresponding command line options. They can be e-mail
  44 addresses or aliases which are automatically expanded to the values
  45 stored in the [mail "alias"] section of GIT configuration files.
  46
  47 A preamble e-mail can be sent using the '--cover' and/or
  48 '--edit-cover' options. The first allows the user to specify a file to
  49 be used as a template. The latter option will invoke the editor on the
  50 specified file (defaulting to '.git/covermail.tmpl' or
  51 '~/.stgit/templates/covermail.tmpl' or
  52 '/usr/share/stgit/templates/covermail.tmpl').
  53
  54 All the subsequent e-mails appear as replies to the first e-mail sent
  55 (either the preamble or the first patch). E-mails can be seen as
  56 replies to a different e-mail by using the '--refid' option.
  57
  58 SMTP authentication is also possible with '--smtp-user' and
  59 '--smtp-password' options, also available as configuration settings:
  60 'smtpuser' and 'smtppassword'. TLS encryption can be enabled by
  61 '--smtp-tls' option and 'smtptls' setting.
  62
  63 The following variables are accepted by both the preamble and the
  64 patch e-mail templates:
  65
  66   %(diffstat)s     - diff statistics
  67   %(number)s       - empty if only one patch is sent or ' patchnr/totalnr'
  68   %(patchnr)s      - patch number
  69   %(sender)s       - 'sender'  or 'authname <authemail>' as per the config file
  70   %(totalnr)s      - total number of patches to be sent
  71   %(version)s      - ' version' string passed on the command line (or empty)
  72
  73 In addition to the common variables, the preamble e-mail template
  74 accepts the following:
  75
  76   %(shortlog)s     - first line of each patch description, listed by author
  77
  78 In addition to the common variables, the patch e-mail template accepts
  79 the following:
  80
  81   %(authdate)s     - patch creation date
  82   %(authemail)s    - author's email
  83   %(authname)s     - author's name
  84   %(commemail)s    - committer's e-mail
  85   %(commname)s     - committer's name
  86   %(diff)s         - unified diff of the patch
  87   %(fromauth)s     - 'From: author\\n\\n' if different from sender
  88   %(longdescr)s    - the rest of the patch description, after the first line
  89   %(patch)s        - patch name
  90   %(prefix)s       - 'prefix ' string passed on the command line
  91   %(shortdescr)s   - the first line of the patch description"""
