[Genparse-users] Descriptive name for long options

[<li...@mi...>]

Hi Mike,

the ls command has a parameter --block-size. If you invoke 
ls --help you see the following description:

...
      --block-size=SIZE      use SIZE-byte blocks
...

I want to make it possible to add such an optional designation 
like "=SIZE" in the ls example above after a long option in the 
Genparse file which can then be referred to in the following 
descriptive text on the help screen.

In the genparse file the following would be allowed:

NONE / block-size=SIZE		int	"use SIZE-byte blocks"

The corresponding line in the genparse style help screen would 
look like this

   [ --block-size=SIZE ] (type=INTEGER)
          use SIZE-byte blocks

This optional descriptive name could be stored in a new string 
_opt_name to the Clparam struct. It would only be used in the
usage() function, nowhere else. And everything stays compatible
because giving an opt_name string in the Genparse file is of 
course optional.

Michael
