Comments on new config system patch

[Matt Sergeant <ma...@sergeant.org>]

Docs:

- Could use some more examples early on e.g. in the paragraph that  
starts "Regular settings consist of..." it should be interspersed  
with some examples.

- The description of the "format" should be moved to later in the  
docs as it's only going to be used as a reference - the most common  
use of these docs will be to lookup the options themselves.

Code:

- Not sure I like globals being $_foo rather than $FOO. I think I'd  
like to see that changed.

- In sub new(), you use indirect object syntax in "my $parser = new  
AxKit2::Config::Parser;" which is frowned on.


Other than that I'm very pleased with the changes. I noted a couple  
of places the docs need fleshed out but you've marked them as such,  
so we can work on that before 1.2.

Matt.
