NAME
       git-mktag - Creates a tag object with extra validation

SYNOPSIS
       git mktag


DESCRIPTION
       Reads a tag’s contents on standard input and creates a tag object. The
       output is the new tag’s <object> identifier.

       This command is mostly equivalent to git-hash-object(1) invoked with -t
       tag -w --stdin. I.e. both of these will create and write a tag found in
       my-tag:

	   git mktag <my-tag
	   git hash-object -t tag -w --stdin <my-tag

       The difference is that mktag will die before writing the tag if the tag
       doesn’t pass a git-fsck(1) check.

       The "fsck" check done by mktag is stricter than what git-fsck(1) would
       run by default in that all fsck.<msg-id> messages are promoted from
       warnings to errors (so e.g. a missing "tagger" line is an error).

       Extra headers in the object are also an error under mktag, but ignored
       by git-fsck(1). This extra check can be turned off by setting the
       appropriate fsck.<msg-id> variable:

	   git -c fsck.extraHeaderEntry=ignore mktag <my-tag-with-headers

OPTIONS
       --strict
	   By default mktag turns on the equivalent of git-fsck(1) --strict
	   mode. Use --no-strict to disable it.

TAG FORMAT
       A tag signature file, to be fed to this command’s standard input, has a
       very simple fixed format: four lines of

	   object <hash>
	   type <typename>
	   tag <tagname>
	   tagger <tagger>

       followed by some optional free-form message (some tags created by older
       Git may not have a tagger line). The message, when it exists, is
       separated by a blank line from the header. The message part may contain
       a signature that Git itself doesn’t care about, but that can be
       verified with gpg.
