Consider command line

   my_prog --output=/tmp/log input.cpp

Here is the option with name "output" and value "/tmp/log". There's also
argument "input.cpp".

The term parameter is undefined yet :-( It's used only as the name of
'parameter' function, and there's something wrong with this name. For
example, when support for argument is added, the same mechanism should be
used to describe type of options and type of arguments. Using 'parameter'
function will became quite confusing, so I'll have to find a better name.
