If an option must be specified, but it need not be specified on the command line, then specify this attribute for the option.

Long-name prefix for enabling the option (invalid if disable not present). Only useful if long option names are being processed.

Prefix for disabling (inverting sense of) the option. Only useful if long option names are being processed.

If default is for option being enabled. (Otherwise, the OPTST_DISABLED bit is set at compile time.) Only useful if the option can be disabled.

For example, if you have a configurable feature, mumble that is indicated with the compile time define, WITH_MUMBLING, then add:


Note that case and spelling must match whatever you are using. Do not confuse these attributes with the AutoGen directives of the same names, See section 2.5 Controlling What Gets Processed. These cause C pre-processing directives to be inserted into the generated C text.
