 786         Add the given repository as a submodule at the given path
 787         to the changeset to be committed next to the current
 788         project: the current project is termed the "superproject".
 789 </p>
 790 <div class="paragraph"><p>&lt;repository&gt; is the URL of the new submodule&#8217;s origin repository.
 791 This may be either an absolute URL, or (if it begins with ./
 792 or ../), the location relative to the superproject&#8217;s default remote
 793 repository (Please note that to specify a repository <em>foo.git</em>
 794 which is located right next to a superproject <em>bar.git</em>, you&#8217;ll
 795 have to use <code>../foo.git</code> instead of <code>./foo.git</code> - as one might expect
 796 when following the rules for relative URLs - because the evaluation
 797 of relative URLs in Git is identical to that of relative directories).</p></div>
 798 <div class="paragraph"><p>The default remote is the remote of the remote-tracking branch
 799 of the current branch. If no such remote-tracking branch exists or
 800 the HEAD is detached, "origin" is assumed to be the default remote.
 801 If the superproject doesn&#8217;t have a default remote configured
 802 the superproject is its own authoritative upstream and the current
 803 working directory is used instead.</p></div>
 804 <div class="paragraph"><p>The optional argument &lt;path&gt; is the relative location for the cloned
 805 submodule to exist in the superproject. If &lt;path&gt; is not given, the
 806 canonical part of the source repository is used ("repo" for
 807 "/path/to/repo.git" and "foo" for "host.xz:foo/.git"). If &lt;path&gt;
 808 exists and is already a valid Git repository, then it is staged
 809 for commit without cloning. The &lt;path&gt; is also used as the submodule&#8217;s
 810 logical name in its configuration entries unless <code>--name</code> is used
 811 to specify a logical name.</p></div>
 812 <div class="paragraph"><p>The given URL is recorded into <code>.gitmodules</code> for use by subsequent users
 813 cloning the superproject. If the URL is given relative to the
 814 superproject&#8217;s repository, the presumption is the superproject and
 815 submodule repositories will be kept together in the same relative
 816 location, and only the superproject&#8217;s URL needs to be provided.
 817 git-submodule will correctly locate the submodule using the relative
 818 URL in <code>.gitmodules</code>.</p></div>

 830         does not match the SHA-1 found in the index of the containing

 850         a template. If the URL is relative, it will be resolved using

1030         of the immediate superproject.
1031         Note that to avoid conflicts with <em>$PATH</em> on Windows, the <em>$path</em>
1032         variable is now a deprecated synonym of <em>$sm_path</em> variable.
1033         Any submodules defined in the superproject but not checked out are
1034         ignored by this command. Unless given <code>--quiet</code>, foreach prints the name
1035         of each submodule before evaluating the command.
1036         If <code>--recursive</code> is given, submodules are traversed recursively (i.e.
1037         the given shell command is evaluated in nested submodules as well).
1038         A non-zero return from the command in any submodule causes
1039         the processing to terminate. This can be overridden by adding <em>|| :</em>
1040         to the end of the command.
