//
//     directry [options] template
//
//     Displays a sorted listing of the given pathnames.  The template
//     may contain wildcard characters.
//
//     options:  One of the following
//
//     -sn        Sort by name
//
//     -sd        Sort by date
//
//     -ss        Sort by size
//
// Parameters
//
//     argc
//
//     The number of arguments passed on the command line.  There must
//     be at least 1 argument other than the command name.
//
//     argv
//
//     A vector of character strings which are the arguments to the
//     command line.
