+=head1 NAME
+
+NOTES_NAME - Configuration for MODULE_NAME
+
+=head1 SYNOPSIS
+
+ use NOTES_NAME;
+ $value = NOTES_NAME->config('foo');
+ $value = NOTES_NAME->feature('bar');
+
+ @names = NOTES_NAME->config_names;
+ @names = NOTES_NAME->feature_names;
+
+ NOTES_NAME->set_config(foo => $new_value);
+ NOTES_NAME->set_feature(bar => $new_value);
+ NOTES_NAME->write; # Save changes
+
+
+=head1 DESCRIPTION
+
+This module holds the configuration data for the C<MODULE_NAME>
+module. It also provides a programmatic interface for getting or
+setting that configuration data. Note that in order to actually make
+changes, you'll have to have write access to the C<NOTES_NAME>
+module, and you should attempt to understand the repercussions of your
+actions.
+
+
+=head1 METHODS
+
+=over 4
+
+=item config($name)
+
+Given a string argument, returns the value of the configuration item
+by that name, or C<undef> if no such item exists.
+
+=item feature($name)
+
+Given a string argument, returns the value of the feature by that
+name, or C<undef> if no such feature exists.
+
+=item set_config($name, $value)
+
+Sets the configuration item with the given name to the given value.
+The value may be any Perl scalar that will serialize correctly using
+C<Data::Dumper>. This includes references, objects (usually), and
+complex data structures. It probably does not include transient
+things like filehandles or sockets.
+
+=item set_feature($name, $value)
+
+Sets the feature with the given name to the given boolean value. The
+value will be converted to 0 or 1 automatically.
+
+=item config_names()
+
+Returns a list of all the names of config items currently defined in
+C<NOTES_NAME>, or in scalar context the number of items.
+
+=item feature_names()
+
+Returns a list of all the names of features currently defined in
+C<NOTES_NAME>, or in scalar context the number of features.
+
+=item auto_feature_names()
+
+Returns a list of all the names of features whose availability is
+dynamically determined, or in scalar context the number of such
+features. Does not include such features that have later been set to
+a fixed value.
+
+=item write()
+
+Commits any changes from C<set_config()> and C<set_feature()> to disk.
+Requires write access to the C<NOTES_NAME> module.
