Update git submodules

* Update docs/submodules/joid from branch 'master'
  - Simplify argument parsing and add usage info

    The code for initial parsing of the script arguments was simplified and
    added better checks of the arguments. For clearer information, usage
    information can be printed out.

    Pod special cases were removed (can be directly specified using custom).
