   9 SYNOPSIS
  10 --------
  11 [verse]
  12 'git mktag'
  13
  14 DESCRIPTION
  15 -----------
  16
  17 Reads a tag's contents on standard input and creates a tag object. The
  18 output is the new tag's <object> identifier.
  19
  20 This command is mostly equivalent to linkgit:git-hash-object[1]
  21 invoked with `-t tag -w --stdin`. I.e. both of these will create and
  22 write a tag found in `my-tag`:
  23
  24     git mktag <my-tag
  25     git hash-object -t tag -w --stdin <my-tag
  26
  27 The difference is that mktag will die before writing the tag if the
  28 tag doesn't pass a linkgit:git-fsck[1] check.
  29
  30 The "fsck" check done by mktag is stricter than what linkgit:git-fsck[1]
  31 would run by default in that all `fsck.<msg-id>` messages are promoted
  32 from warnings to errors (so e.g. a missing "tagger" line is an error).
  33
  34 Extra headers in the object are also an error under mktag, but ignored
  35 by linkgit:git-fsck[1]. This extra check can be turned off by setting
  36 the appropriate `fsck.<msg-id>` variable:
  37
  38     git -c fsck.extraHeaderEntry=ignore mktag <my-tag-with-headers
  39
  40 OPTIONS
  41 -------
  42
  43 --strict::
  44         By default mktag turns on the equivalent of
  45         linkgit:git-fsck[1] `--strict` mode. Use `--no-strict` to
  46         disable it.
  47
  48 Tag Format
  49 ----------
  50 A tag signature file, to be fed to this command's standard input,
  51 has a very simple fixed format: four lines of
  52
  53   object <hash>
  54   type <typename>
  55   tag <tagname>
  56   tagger <tagger>
  57
  58 followed by some 'optional' free-form message (some tags created
  59 by older Git may not have a `tagger` line).  The message, when it
  60 exists, is separated by a blank line from the header.  The
  61 message part may contain a signature that Git itself doesn't
  62 care about, but that can be verified with gpg.
