+ * Compiles less files.
+ *
+ * ```php
+ * <?php
+ * $this->taskLess([
+ *     'less/default.less' => 'css/default.css'
+ * ])
+ * ->run();
+ * ?>
+ * ```
+ *
+ * Use one of both less compilers in your project:
+ *
+ * ```
+ * "leafo/lessphp": "~0.5",
+ * "oyejorge/less.php": "~1.5"
+ * ```
+ *
+ * Specify directory (string or array) for less imports lookup:
+ *
+ * ```php
+ * <?php
+ * $this->taskLess([
+ *     'less/default.less' => 'css/default.css'
+ * ])
+ * ->importDir('less')
+ * ->compiler('lessphp')
+ * ->run();
+ * ?>
+ * ```
+ *
+ * You can implement additional compilers by extending this task and adding a
+ * method named after them and overloading the lessCompilers() method to
+ * inject the name there.
