[Coin-discuss] parameter parser

[Matthew Galati]

Hi --

I looked at your OptionsList class. I think I see how to register 
options and how to read options from a file. Is it possible to read from 
a file, but then override an option at the command line?

For example - how would I do something like:

opts.txt:
optionA = 2
optionB= "ddd"

./myapp --param opts.txt --optionA 4

which would read opts.txt, but then override option1 to 4 based on 
command line?

Thanks,
Matt
