VistaIO Version 1.2.14                            24 April 1993                            VistaIOReportUsage(3)

VistaIOReportUsage prints, to the standard error stream, information about how to use a program. It first
       prints a line of the form:

              Usage:program<options>other_args,where<options>includes:

       The program argument supplies the program component of this line, and the  other_args  argument  supplies
       the  other_args  component.  If  the program accepts no options other than those described in the options
       table, other_args should be NULL.

       VistaIOReportUsage then calls VistaIOReportValidOptions to print a summary of the  options  described  by
       noptions and options.

       VistaIOReportValidOptions  prints  a  description  of  each  option in a table of option descriptors. The
       description is intended to advise a program  user.   It  indicates  what  keyword  signals  the  option's
       presence  in  the  command  line, whether it is optional, how many values must follow it, what type those
       values should have, what keywords may be used as values for the option, and  what  default  value(s)  the
       option  has.  The description will also include any ``blurb'' string of help information that is found in
       the option's table entry. The information is printed to the standard error stream.
