Agreed. The current implementation uses atoi(value), which just returns
zero on failure, and doesn't output a warning to the user.
Concering -v, I now changed the png2swf/jpeg2swf syntax to the -v, -vv,
-vvv syntax used by all the other tools anyway, but it probably still
needs to be fixed for things like -q <quality>.

I only break things into option/value where the command itself dictates
(in one of the callback functions), that it needs a value.
I'm not sure why you think the argument processing itself is flawed-
Could you elaborate?
