577     # Takes one first argument (called spec), which dictates how to parse and 
578     # the rest of the arguments are parsed. Outputs a piece of valid shell code 
579     # that can be passed to `eval` inside a function which creates the arguments 
580     # and their values as local variables. Suggested use is to set the defaults 
581     # to all arguments first and then eval the output of this function. 
582  
583     # Spec: Only long argument supported. No support for parsing short options. 
584     # The spec must have two sections, separated by a `;`.
