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

/**
 * Main upgrade tasks to be executed on Moodle version bump
 *
 * This function is automatically executed after one bump in the Moodle core
 * version is detected. It's in charge of performing the required tasks
 * to raise core from the previous version to the next one.
 *
 * It's a collection of ordered blocks of code, named "upgrade steps",
 * each one performing one isolated (from the rest of steps) task. Usually
 * tasks involve creating new DB objects or performing manipulation of the
 * information for cleanup/fixup purposes.
 *
 * Each upgrade step has a fixed structure, that can be summarised as follows:
 *
 * if ($oldversion < XXXXXXXXXX.XX) {
 *     // Explanation of the update step, linking to issue in the Tracker if necessary
 *     upgrade_set_timeout(XX); // Optional for big tasks
 *     // Code to execute goes here, usually the XMLDB Editor will
 *     // help you here. See {@link http://docs.moodle.org/dev/XMLDB_editor}.
 *     upgrade_main_savepoint(true, XXXXXXXXXX.XX);
 * }
 *
 * All plugins within Moodle (modules, blocks, reports...) support the existence of
 * their own upgrade.php file, using the "Frankenstyle" component name as
 * defined at {@link http://docs.moodle.org/dev/Frankenstyle}, for example:
 *     - {@link xmldb_page_upgrade($oldversion)}. (modules don't require the plugintype ("mod_") to be used.
 *     - {@link xmldb_auth_manual_upgrade($oldversion)}.
 *     - {@link xmldb_workshopform_accumulative_upgrade($oldversion)}.
 *     - ....
 *
 * In order to keep the contents of this file reduced, it's allowed to create some helper
 * functions to be used here in the {@link upgradelib.php} file at the same directory. Note
 * that such a file must be manually included from upgrade.php, and there are some restrictions
 * about what can be used within it.
 *
 * For more information, take a look to the documentation available:
 *     - Data definition API: {@link http://docs.moodle.org/dev/Data_definition_API}
 *     - Upgrade API: {@link http://docs.moodle.org/dev/Upgrade_API}
 *
 * @param int $oldversion
 * @return bool always true
