There are two kinds of options that can be passed to Autodir. In the first type, options are for autodir itself and are common irrespective of which module is used. The other type of options are specific to the module being used. These options are called suboptions and are passed to the module being used; they are different from the main -o option. This is similar to the suboptions used with the mount command.
For example, suboptions to the example module autohome can be passed as follows:
Here realpath, level and noskel are suboptions for autohome module.
