  18 =head1 DESCRIPTION
  19
  20 Call as many C<git submodule add ...> commands as many submodules are defined in
  21 F<.gitmodules> file in the current repo's root.
  22 Automatically adding submodules this way.
  23
  24 An extra feature is to able to define on which name the submodule's remote should
  25 be called ("origin" or the tracking remote of superproject's current branch,
  26 see git-submodule(1) for details). Add B<remotename> option to the submodule's section
  27 in F<.gitmodules> to achieve this.
