8.4.2 Option Attributes

For each option you wish to specify, you must have a block macro named flag defined. It MUST contain at least two defined text values named name and descrip. If any options do not have a value macro, then the long-opts global text macro must 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.

There are four categories of option attributes. The fifth section below describes what data are available for writing option processing code.
