<title>GSettings</title>

  <p>GSettings is the part of <link xref="tech-glib">GLib</link> that allows
  applications to save their configuration settings and user's preferences in a
  standard way.</p>

  <p>
    An application that uses GSettings defines a <em>schema</em> of
    configuration keys.  The schema for each key contains the key's name, a
    human-readable description of what the key is for, a type for the key
    (string, integer, etc.), and a default value.
  </p>

  <p>
    GSettings uses the operating system's storage for configuration data.  On
    GNU systems this is DConf; on Windows it is the Registry, and on Mac OS it
    is the NextStep property list mechanism.
  </p>

  <p>
    GSettings lets you monitor changes in keys' values, so your application can
    respond dynamically to global changes in configuration.  For example, all
    applications that display clocks can respond to a global setting for
    12-hour/24-hour display immediately, without having to restart.
