+/**
+ * Spaceless widget removes whitespace characters between HTML tags. Whitespaces within HTML tags
+ * or in a plain text are always left untouched.
+ *
+ * Usage example:
+ *
+ * ```php
+ * <body>
+ *     <?php Spaceless::begin(); ?>
+ *         <div class="nav-bar">
+ *             <!-- tags -->
+ *         </div>
+ *         <div class="content">
+ *             <!-- tags -->
+ *         </div>
+ *     <?php Spaceless::end(); ?>
+ * </body>
+ * ```
+ *
+ * This example will generate the following HTML:
+ *
+ * ```html
+ * <body>
+ *     <div class="nav-bar"><!-- tags --></div><div class="content"><!-- tags --></div></body>
+ * ```
+ *
+ * This method is not designed for content compression (you should use `gzip` output compression to
+ * achieve it). Main intention is to strip out extra whitespace characters between HTML tags in order
+ * to avoid browser rendering quirks in some circumstances (e.g. newlines between inline-block elements).
+ *
+ * Note, never use this method with `pre` or `textarea` tags. It's not that trivial to deal with such tags
+ * as it may seem at first sight. For this case you should consider using
+ * [HTML Tidy Project](http://tidy.sourceforge.net/) instead.
+ *
