+    // Use the PRE_VALID header. This means less output source since we don't have to output &nbsp;
+    // everywhere. Of course it also means you can't set the tab width.
+    // HEADER_PRE_VALID puts the <pre> tag inside the list items (<li>) thus producing valid HTML markup.
+    // HEADER_PRE puts the <pre> tag around the list (<ol>) which is invalid in HTML 4 and XHTML 1
+    // HEADER_DIV puts a <div> tag arount the list (valid!) but needs to replace whitespaces with &nbsp
+    //            thus producing much larger overhead. You can set the tab width though.
+    $geshi->set_header_type(GESHI_HEADER_PRE_VALID);
+
+    // Enable CSS classes. You can use get_stylesheet() to output a stylesheet for your code. Using
+    // CSS classes results in much less output source.

+
+    // Enable line numbers. We want fancy line numbers, and we want every 5th line number to be fancy
+    $geshi->enable_line_numbers(GESHI_FANCY_LINE_NUMBERS, 5);
+
+    // Set the style for the PRE around the code. The line numbers are contained within this box (not

+    // you don't want this. So the set_code_style reverts styles for the line (by using a <div> on the line).
+    // So the source output looks like this:
+    //
+    // <pre style="[set_overall_style styles]"><ol>
