 COMMANDS
 --------
+add::
+       Add the given repository as a submodule at the given path
+       to the changeset to be committed next.  In particular, the
+       repository is cloned at the specified path, added to the
+       changeset and registered in .gitmodules.   If no path is
+       specified, the path is deduced from the repository specification.
+       If the repository url begins with ./ or ../, it is stored as
+       given but resolved as a relative path from the main project's
+       url when cloning.

 status::
