Re: getopt

Suppose you have:

#!/usr/bin/octave -qf

## Command line defaults
opt.help = false ;
opt.pdb = false ;
opt.fileA = "" ;
opt.fileB = "" ;

## Process command line options
args = argv() ;
i = 1 ;
while i <= length(args)
    option = args{i} ;
    switch option
    case {"-h" "--help"}
        opt.help = true ;
    case {"-p" "--pdb"}
        opt.pdb = true ;
    otherwise
        break ;
    endswitch
    i++ ;
endwhile

if opt.help
    opt
    disp("Usage") ;
    exit(1) ;
endif

opt.fileA = args{i++} ;
opt.fileB = args{i++} ;
opt
