7.3.4 Option Attributes

For each option you wish to specify, you must have a block macro named flag defined. There are two required attributes: name and descrip. If any options do not have a value (traditional flag character) attribute, then the long-opts global text macro must also be defined. As a special exception, if no options have a value and long-opts is not defined and argument is not defined, then all arguments to the program are named. In this case, the - and -- command line option markers are optional.
