option_is_set
Checks whether an option has been explicitly set by a script or from the command line or whether the option has a default value or computed value (return value of a func).
parse
Reads options from the command line, an environment variable, or a configuration file and transforms the option into appropriate data structures for validation.
validate
Ensures that input values (from the command line, an environment variable, or a configuration file) are complete, consistent, and valid.
