31 Send a patch or a range of patches by e-mail using the 'smtpserver'
32 configuration option. The From address and the e-mail format are
33 generated from the template file passed as argument to '--template'
34 (defaulting to '.git/patchmail.tmpl' or
35 '~/.stgit/templates/patchmail.tmpl' or or
36 '/usr/share/stgit/templates/patchmail.tmpl'). The To/Cc/Bcc addresses
37 can either be added to the template file or passed via the
38 corresponding command line options.
40 A preamble e-mail can be sent using the '--cover' and/or
41 '--edit-cover' options. The first allows the user to specify a file to
42 be used as a template. The latter option will invoke the editor on the
43 specified file (defaulting to '.git/covermail.tmpl' or
44 '~/.stgit/templates/covermail.tmpl' or
45 '/usr/share/stgit/templates/covermail.tmpl').
47 All the subsequent e-mails appear as replies to the first e-mail sent
48 (either the preamble or the first patch). E-mails can be seen as
49 replies to a different e-mail by using the '--refid' option.
51 SMTP authentication is also possible with '--smtp-user' and
52 '--smtp-password' options, also available as configuration settings:
53 'smtpuser' and 'smtppassword'.
55 The patch e-mail template accepts the following variables:
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 %(diff)s - unified diff of the patch
62 %(diffstat)s - diff statistics
63 %(version)s - ' version' string passed on the command line (or empty)
64 %(prefix)s - 'prefix ' string passed on the command line
65 %(patchnr)s - patch number
66 %(totalnr)s - total number of patches to be sent
67 %(number)s - empty if only one patch is sent or ' patchnr/totalnr'
68 %(authname)s - author's name
69 %(authemail)s - author's email
70 %(authdate)s - patch creation date
71 %(commname)s - committer's name
72 %(commemail)s - committer's e-mail
74 For the preamble e-mail template, only the %(maintainer)s,
75 %(version)s, %(patchnr)s, %(totalnr)s and %(number)s variables are
