  31 usage = [' [options] [<patch1>] [<patch2>] [<patch3>..<patch4>]']
  32 description = r"""
  33 Send a patch or a range of patches by e-mail using the SMTP server
  34 specified by the 'stgit.smtpserver' configuration option, or the
  35 '--smtp-server' command line option. This option can also be an
  36 absolute path to 'sendmail' followed by command line arguments.
  37
  38 The From address and the e-mail format are generated from the template
  39 file passed as argument to '--template' (defaulting to
  40 '.git/patchmail.tmpl' or '~/.stgit/templates/patchmail.tmpl' or
  41 '/usr/share/stgit/templates/patchmail.tmpl'). A patch can be sent as
  42 attachment using the --attach option in which case the
  43 'mailattch.tmpl' template will be used instead of 'patchmail.tmpl'.
  44
  45 The To/Cc/Bcc addresses can either be added to the template file or
  46 passed via the corresponding command line options. They can be e-mail
  47 addresses or aliases which are automatically expanded to the values
  48 stored in the [mail "alias"] section of GIT configuration files.
  49
  50 A preamble e-mail can be sent using the '--cover' and/or
  51 '--edit-cover' options. The first allows the user to specify a file to
  52 be used as a template. The latter option will invoke the editor on the
  53 specified file (defaulting to '.git/covermail.tmpl' or
  54 '~/.stgit/templates/covermail.tmpl' or
  55 '/usr/share/stgit/templates/covermail.tmpl').
  56
  57 All the subsequent e-mails appear as replies to the first e-mail sent
  58 (either the preamble or the first patch). E-mails can be seen as
  59 replies to a different e-mail by using the '--refid' option.
  60
  61 SMTP authentication is also possible with '--smtp-user' and
  62 '--smtp-password' options, also available as configuration settings:
  63 'smtpuser' and 'smtppassword'. TLS encryption can be enabled by
  64 '--smtp-tls' option and 'smtptls' setting.
  65
  66 The following variables are accepted by both the preamble and the
  67 patch e-mail templates:
  68
  69   %(diffstat)s     - diff statistics
  70   %(number)s       - empty if only one patch is sent or ' patchnr/totalnr'
  71   %(patchnr)s      - patch number
  72   %(sender)s       - 'sender'  or 'authname <authemail>' as per the config file
  73   %(totalnr)s      - total number of patches to be sent
  74   %(version)s      - ' version' string passed on the command line (or empty)
  75
  76 In addition to the common variables, the preamble e-mail template
  77 accepts the following:
  78
  79   %(shortlog)s     - first line of each patch description, listed by author
  80
  81 In addition to the common variables, the patch e-mail template accepts
  82 the following:
  83
  84   %(authdate)s     - patch creation date
  85   %(authemail)s    - author's email
  86   %(authname)s     - author's name
  87   %(commemail)s    - committer's e-mail
  88   %(commname)s     - committer's name
  89   %(diff)s         - unified diff of the patch
  90   %(fromauth)s     - 'From: author\n\n' if different from sender
  91   %(longdescr)s    - the rest of the patch description, after the first line
  92   %(patch)s        - patch name
  93   %(prefix)s       - 'prefix ' string passed on the command line
  94   %(shortdescr)s   - the first line of the patch description"""
