|The index of the entry in the arguments array that should be used for this option's argument. |
|The flag bit that represents this option. |
Application 'options' are single-character flags that can be supplied to the application to affect its behavior; they can also optionally accept arguments enclosed in parenthesis.
These structures are used by the ast_app_parse_options function, uses this data to fill in a flags structure (to indicate which options were supplied) and array of argument pointers (for those options that had arguments supplied).
