- The `OPTION` command:
  - The `OPTION` command provides an easy way to create a simple option tree with the default directory structure. The easiest way to do this is :
    1. Choose a name for the option tree.
    2. Choose a directory for the option tree to be placed in (if the directory does not exist it will be created automatically).
    3. Use the `/CREATE` feature of the `OPTION` command to create (just the first time) the default directories and include a template command dictionary:

           nM> option/create <name> <path to option tree>

       For example:

           nM> option/create myopt /home/smith/myopt123/nxm/myopt

    4. NOTE: Subsequent times, you will define your option tree WITHOUT the /create switch, e.g.

           nM> option myopt /home/smith/myopt123/nxm/myopt

  - For other methods of creating an option tree using the `OPTION` command please see the `OPTION` explain file.
