=head1 NAME
Config::Onion::Simple - Simple interface to a Config::Onion singleton
=head1 VERSION
version 1.007
=head1 SYNOPSIS
use Config::Onion::Simple qw( cfg cfg_obj );
cfg_obj->load('myapp');
my $setting = cfg->{setting};
=head1 DESCRIPTION
It is often useful for a single master configuration to be shared across
multiple modules in an application. Config::Onion::Simple provides an
interface to do this without requiring any of those modules to know about
each other.
=head1 EXPORTABLE FUNCTIONS
Config::Onion::Simple exports nothing by default. The following functions
are exported only on request.
=head2 cfg
Returns a reference to the complete configuration hash managed by the
Config::Onion singleton. This hash should be treated as read-only, as any
changes will be lost if the configuration is altered using the underlying
Config::Onion instance's methods.
Calling C<cfg> is equivalent to calling C<< cfg_obj->get >>.
=head2 cfg_obj
Returns a reference to the Config::Onion singleton. Use this object's methods
to make any changes to the configuration.
