If possible you could try docopt. That should be able to do it quite easily.

You could write literally:

    My-Script

    Usage:
      my-script (-a -b VALUE-B | -c -d VALUE-D)

    Options:
      -b VALUE-B  Description
      -d VALUE-D  Description

as the grammar, but:

    My-Script

    Usage:
      my-script -a -b VALUE-B
      my-script -c -d VALUE-D

    Options:
      -b VALUE-B  Description
      -d VALUE-D  Description

would be preferred.
