      $output .= "<p>The sidebar each block appears in depends on both which theme you're using (some are left-only, some right, some both), and on the settings in block management.</p><p>Whether a block is visible in the first place depends on three things:</p><ul><li>It must have its \"enabled\" box checked in block management.</li><li>If it has its \"custom\" box checked in block management, the user must have chosen to display it in their user preferences.</li><li>If the \"path\" field in block management is set, the visitor must be on a page that matches the path specification (more on this later).</li></ul>";

Lighter blocks (smaller weight) \"float up\" towards the top of the sidebar. Heavier ones \"sink down\" towards the bottom of it. Once you've positioned things just so, you can preview what the layout will look like in different types of themes by clicking the preview placement link in the menu to the left.</p>";

      $output .= "<p>If the block should only show up on blog pages, use &lt;/blog&gt;.  To display on all node views use &lt;/node/view&gt;.  The angular brackets are used as delimiters of the regular expression.  To show up on either forum or book pages use &lt;(/forum|/book)&gt;.  The round brackets form a group of expressions, divided by the | character. It matches if any of the expressions in it match.  A more complicated example is &lt;/node/add/(story|blog|image)&gt;. Blocks which have their paths set to this expression will show up on story, block, or image composition pages.  If you want to show a block an all pages, but not the search page, use &lt;(^/$|[^(search)$/]+)&gt;</p>";

Each custom block consists of a title, a description, and a body containing text, HTML, or PHP code which can be as long as you wish. The Drupal engine will 'render' the content of the custom block.</p>";

      $output .= "<p>If you know how to script in PHP, Drupal gives you the power to embed any script you like inside a block. It will be executed when the page is viewed and dynamically embedded into the page. This gives you amazing flexibility and power, but of course with that comes danger and insecurity if you don't write good code. If you are not familiar with PHP, SQL or with the site engine, avoid experimenting with PHP custom blocks because you can corrupt your database or render your site insecure or even unusable! If you don't plan to do fancy stuff with custom blocks then you're probably better off with straight HTML.</p>";
      $output .= "<p>Remember that the code within each PHP custom block must be valid PHP code - including things like correctly terminating statements with a semicolon so that the parser won't die. It is highly recommended that you develop your cusom blocks separately using a simple test script on top of a test database before migrating to your production environment.</p>";
      $output .= "<p>Notes:</p><ul><li>You can use global variables, such as configuration parameters, within the scope of a PHP box but remember that variables which have been given values in a PHP box will retain these values in the engine or module afterwards.</li><li>register_globals is now set to <b>off</b> by default. If you need form information you need to get it from the \"superglobals\" \$_POST, \$_GET, etc.</li><li>You can use the <code>return</code> statement to return the actual content for your block as well.</li></ul>";
