7.3.7 Library of Standard Options

AutoOpts has developed a set of standardized options. You may incorporate these options in your program simply by first adding a #define for the options you want, and then the line,

#include stdoptions.def

in your option definitions. The supported options are specified thus:

#define DEBUG #define DIRECTORY #define DRY_RUN #define INPUT #define INTERACTIVE #define OUTPUT #define WARN #define SILENT #define QUIET #define BRIEF #define VERBOSE

By default, only the long form of the option will be available. To specify the short (flag) form, suffix these names with _FLAG. e.g.,

#define DEBUG_FLAG

--silent, --quiet, --brief and --verbose are related in that they all indicate some level of diagnostic output. These options are all designed to conflict with each other. Instead of four different options, however, several levels can be incorporated by #define-ing VERBOSE_ENUM. In conjunction with VERBOSE, it incorporates the notion of 5 levels in an enumeration: silent, quiet, brief, informative and verbose; with the default being brief.
