=head1 NAME
ExtUtils::Config - A wrapper for perl's configuration
=head1 VERSION
version 0.008
=head1 SYNOPSIS
my $config = ExtUtils::Config->new();
$config->get('installsitelib');
=head1 DESCRIPTION
ExtUtils::Config is an abstraction around the %Config hash. By itself it is not a particularly interesting module by any measure, however it ties together a family of modern toolchain modules.
=head1 METHODS
=head2 new(\%config)
Create a new ExtUtils::Config object. The values in C<\%config> are used to initialize the object.
=head2 get($key)
Get the value of C<$key>. If not overridden it will return the value in %Config.
=head2 exists($key)
Tests for the existence of $key.
=head2 values_set()
Get a hashref of all overridden values.
=head2 all_config()
Get a hashref of the complete configuration, including overrides.
=head2 serialize()
This method serializes the object to some kind of string.
