/**
 * The GSettingsSchemaSource and GSettingsSchema APIs provide a
 * mechanism for advanced control over the loading of schemas and a
 * mechanism for introspecting their content.
 *
 * Plugin loading systems that wish to provide plugins a way to access
 * settings face the problem of how to make the schemas for these
 * settings visible to GSettings. Typically, a plugin will want to ship
 * the schema along with itself and it won't be installed into the
 * standard system directories for schemas.
 *
 * GSettingsSchemaSource provides a mechanism for dealing with this by
 * allowing the creation of a new 'schema source' from which schemas can
 * be acquired. This schema source can then become part of the metadata
 * associated with the plugin and queried whenever the plugin requires
 * access to some settings.
 *
 * Consider the following example:
 *
 * $(DDOC_COMMENT example)
 *
 * The code above shows how hooks should be added to the code that
 * initialises (or enables) the plugin to create the schema source and
 * how an API can be added to the plugin system to provide a convenient
 * way for the plugin to access its settings, using the schemas that it
 * ships.
 *
 * From the standpoint of the plugin, it would need to ensure that it
 * ships a gschemas.compiled file as part of itself, and then simply do
 * the following:
 *
 * $(DDOC_COMMENT example)
 *
 * It's also possible that the plugin system expects the schema source
 * files (ie: .gschema.xml files) instead of a gschemas.compiled file.
 * In that case, the plugin loading system must compile the schemas for
 * itself before attempting to create the settings source.
