+=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.
