  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()}.
