  32   * Main post-install tasks to be executed after the BD schema is available
  33   *
  34   * This function is automatically executed after Moodle core DB has been
  35   * created at initial install. It's in charge of perform the initial tasks
  36   * not covered by the {@link install.xml} file, like create initial users,
  37   * roles, templates, moving stuff from other plugins...
  38   *
  39   * Note that the function is only invoked once, at install time, so if new tasks
  40   * are needed in the future, they will need to be added both here (for new sites)
  41   * and in the corresponding {@link upgrade.php} file (for existing sites).
  42   *
  43   * All plugins within Moodle (modules, blocks, reports...) support the existence of
  44   * their own install.php file, using the "Frankenstyle" component name as
  45   * defined at {@link http://docs.moodle.org/dev/Frankenstyle}, for example:
  46   *     - {@link xmldb_page_install()}. (modules don't require the plugintype ("mod_") to be used.
  47   *     - {@link xmldb_enrol_meta_install()}.
  48   *     - {@link xmldb_workshopform_accumulative_install()}.
  49   *     - ....
  50   *
  51   * Finally, note that it's also supported to have one uninstall.php file that is
  52   * executed also once, each time one plugin is uninstalled (before the DB schema is
  53   * deleted). Those uninstall files will contain one function, using the "Frankenstyle"
  54   * naming conventions, like {@link xmldb_enrol_meta_uninstall()} or {@link xmldb_workshop_uninstall()}.
