  // Function :
  //   create($p_filelist, $p_add_dir="", $p_remove_dir="")
  //   create($p_filelist, $p_option, $p_option_value, ...)
  // Description :
  //   This method supports two different synopsis. The first one is historical.
  //   This method creates a Zip Archive. The Zip file is created in the
  //   filesystem. The files and directories indicated in $p_filelist
  //   are added in the archive. See the parameters description for the
  //   supported format of $p_filelist.
  //   When a directory is in the list, the directory and its content is added
  //   in the archive.
  //   In this synopsis, the function takes an optional variable list of
  //   options. See below the supported options.
  // Parameters :
  //   $p_filelist : An array containing file or directory names, or
  //                 a string containing one filename or one directory name, or
  //                 a string containing a list of filenames and/or directory
  //                 names separated by spaces.
  //   $p_add_dir : A path to add before the real path of the archived file,
  //                in order to have it memorized in the archive.
  //   $p_remove_dir : A path to remove from the real path of the file to archive,
  //                   in order to have a shorter path memorized in the archive.
  //                   When $p_add_dir and $p_remove_dir are set, $p_remove_dir
  //                   is removed first, before $p_add_dir is added.
  // Options :
  //   PCLZIP_OPT_ADD_PATH :
  //   PCLZIP_OPT_REMOVE_PATH :
  //   PCLZIP_OPT_REMOVE_ALL_PATH :
  //   PCLZIP_OPT_COMMENT :
  //   PCLZIP_CB_PRE_ADD :
  //   PCLZIP_CB_POST_ADD :
  // Return Values :
  //   0 on failure,
  //   The list of the added files, with a status of the add action.
  //   (see PclZip::listContent() for list entry format)

/**
 * WordPress Filesystem Class for implementing SSH2
 *
 * To use this class you must follow these steps for PHP 5.2.6+
 *
 * {@link http://kevin.vanzonneveld.net/techblog/article/make_ssh_connections_with_php/ - Installation Notes}
 *
 * Compile libssh2 (Note: Only 0.14 is officially working with PHP 5.2.6+ right now, But many users have found the latest versions work)
 *
 * cd /usr/src
 * wget https://www.libssh2.org/download/libssh2-0.14.tar.gz
 * tar -zxvf libssh2-0.14.tar.gz
 * cd libssh2-0.14/
 * ./configure
 * make all install
 *
 * Note: Do not leave the directory yet!
 *
 * Enter: pecl install -f ssh2
 *
 * Copy the ssh.so file it creates to your PHP Module Directory.
 * Open up your PHP.INI file and look for where extensions are placed.
 * Add in your PHP.ini file: extension=ssh2.so
 *
 * Restart Apache!
 * Check phpinfo() streams to confirm that: ssh2.shell, ssh2.exec, ssh2.tunnel, ssh2.scp, ssh2.sftp  exist.
 *
 * Note: As of WordPress 2.8, this utilizes the PHP5+ function `stream_get_contents()`.

		 * Filters which site status tests are run on a site.

		 * checks may be handled by a host, and are therefore disabled in core.
		 * Or maybe you want to introduce a new test, is caching enabled/disabled/stale for example.
		 *
		 * Tests may be added either as direct, or asynchronous ones. Any test that may require some time
		 * to complete should run asynchronously, to avoid extended loading periods within wp-admin.
		 *
		 * @since 5.2.0
		 * @since 5.6.0 Added the `async_direct_test` array key for asynchronous tests.

/**
 * WordPress Plugin Install Administration API

 * @subpackage Administration
 */

/**
 * Retrieves plugin installer pages from the WordPress.org Plugins API.
 *
 * It is possible for a plugin to override the Plugin API result with three
 * filters. Assume this is for plugins, which can extend on the Plugin Info to
 * offer more choices. This is very powerful and must be used with care when
 * overriding the filters.
 *
 * The first filter, {@see 'plugins_api_args'}, is for the args and gives the action
 * as the second parameter. The hook for {@see 'plugins_api_args'} must ensure that
 * an object is returned.
 *
 * The second filter, {@see 'plugins_api'}, allows a plugin to override the WordPress.org
 * Plugin Installation API entirely. If `$action` is 'query_plugins' or 'plugin_information',
 * an object MUST be passed. If `$action` is 'hot_tags', an array MUST be passed.
 *
 * Finally, the third filter, {@see 'plugins_api_result'}, makes it possible to filter the
 * response object or array, depending on the `$action` type.
 *
 * Supported arguments per action:
 *
 * | Argument Name        | query_plugins | plugin_information | hot_tags |
 * | -------------------- | :-----------: | :----------------: | :------: |
 * | `$slug`              | No            |  Yes               | No       |
 * | `$per_page`          | Yes           |  No                | No       |
 * | `$page`              | Yes           |  No                | No       |
 * | `$number`            | No            |  No                | Yes      |
 * | `$search`            | Yes           |  No                | No       |
 * | `$tag`               | Yes           |  No                | No       |
 * | `$author`            | Yes           |  No                | No       |
 * | `$user`              | Yes           |  No                | No       |
 * | `$browse`            | Yes           |  No                | No       |
 * | `$locale`            | Yes           |  Yes               | No       |
 * | `$installed_plugins` | Yes           |  No                | No       |

 *          located in.
 *     Network: Optional. Specify "Network: true" to require that a plugin is activated

/**
 * Retrieves theme installer pages from the WordPress.org Themes API.
 *
 * It is possible for a theme to override the Themes API result with three
 * filters. Assume this is for themes, which can extend on the Theme Info to
 * offer more choices. This is very powerful and must be used with care, when
 * overriding the filters.
 *
 * The first filter, {@see 'themes_api_args'}, is for the args and gives the action
 * as the second parameter. The hook for {@see 'themes_api_args'} must ensure that
 * an object is returned.
 *
 * The second filter, {@see 'themes_api'}, allows a plugin to override the WordPress.org
 * Theme API entirely. If `$action` is 'query_themes', 'theme_information', or 'feature_list',
 * an object MUST be passed. If `$action` is 'hot_tags', an array should be passed.
 *
 * Finally, the third filter, {@see 'themes_api_result'}, makes it possible to filter the
 * response object or array, depending on the `$action` type.
 *
 * Supported arguments per action:
 *
 * | Argument Name      | 'query_themes' | 'theme_information' | 'hot_tags' | 'feature_list'   |
 * | -------------------| :------------: | :-----------------: | :--------: | :--------------: |

 * The files in the `$_old_files` list will be removed and the new files
 * copied from the zip file after the database is upgraded.
 *
 * The files in the `$_new_bundled_files` list will be added to the installation
 * if the version is greater than or equal to the old version being upgraded.
 *
 * The steps for the upgrader for after the new release is downloaded and
 * unzipped is:
 *
 *   1. Test unzipped location for select files to ensure that unzipped worked.
 *   2. Create the .maintenance file in current WordPress base.
 *   3. Copy new WordPress directory over old WordPress files.
 *   4. Upgrade WordPress to new version.
 *      1. Copy all files/folders other than wp-content
 *      2. Copy any language files to `WP_LANG_DIR` (which may differ from `WP_CONTENT_DIR`
 *      3. Copy any new bundled themes/plugins to their respective locations
 *   5. Delete new WordPress directory path.
 *   6. Delete .maintenance file.
 *   7. Remove old files.
 *   8. Delete 'update_core' option.
 *
 * There are several areas of failure. For instance if PHP times out before step
 * 6, then you will not be able to access any portion of your site. Also, since
 * the upgrade will not continue where it left off, you will not be able to
 * automatically remove old files and remove the 'update_core' option. This
 * isn't that bad.
 *
 * If the copy of the new WordPress over the old fails, then the worse is that
 * the new WordPress directory will remain.
 *
 * If it is assumed that every file will be copied over, including plugins and
 * themes, then if you edit the default theme, you should rename it, so that
 * your changes remain.
