+NAME
+----
+git-mktag - Creates a tag object
+
+
+SYNOPSIS
+--------
+[verse]
+'git mktag'
+
+DESCRIPTION
+-----------
+Reads a tag contents on standard input and creates a tag object
+that can also be used to sign other objects.
+
+The output is the new tag's <object> identifier.
+
+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 <sha1>
+  type <typename>
+  tag <tagname>
+  tagger <tagger>
+
+followed by some 'optional' free-form message (some tags created
+by older Git may not have `tagger` line).  The message, when
+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.
